How to delete duplicate photos on Android step by step

Informatec Digital » Resources » How to delete duplicate photos on Android step by step

If you've been using the same phone for a while, chances are your Android gallery is full of duplicate photos , repeated WhatsApp images, and a good number of nearly identical screenshots. All of this translates to something very simple: wasted phone storage space . It's worth knowing which files are taking up space and, in the long run, can lead to a slower phone and problems installing apps or taking new photos.

The good news is that nowadays there are very reliable tools for finding and deleting duplicate photos on Android without driving yourself crazy checking them one by one. Some come pre-installed (like Files by Google or Google Photos), while others are dedicated apps like Remo Duplicate Photos Remover or other similar "duplicate photo remover" programs. Let's look, step by step and in detail, at all the practical ways to locate duplicate images and safely delete them , avoiding accidentally deleting important originals.

Why do Android phones get filled with duplicate photos?

If you use your phone for everything, it's normal to accumulate hundreds or thousands of images spread across your camera, WhatsApp, Telegram, Instagram, and other apps . Each application saves copies, edits, and downloads in its own folders, causing the number of photos to multiply without us even realizing it.

Often, we also take several nearly identical photos in burst mode , try different filters, crop, edit, or forward images. The result is that storage space fills up with duplicate or very similar versions of the same photo, taking up room without adding anything new.

In addition, messaging apps like WhatsApp automatically download photos and videos sent by contacts, even if you've already saved them manually or forwarded them. You might also download the same image from social media more than once.

All that chaos makes managing your gallery manually almost impossible over time . That's why it's so useful to use apps that analyze your internal memory and SD card, group identical or similar photos, and make it easy to delete copies you no longer need.

Use Files by Google to delete duplicate photos on Android

One of the easiest and safest ways to clean up duplicates is to use Files by Google , Google's official file management app, which comes pre-installed on many modern Android phones. In addition to organizing folders, it also includes a smart cleanup feature that detects duplicate files, including photos.

It works very easily because the app itself tells you which are the copies and which is the original file . The main file is marked with a small badge that says "Original," so you know which photo you should keep to avoid losing the reference version.

To use it, the basic process is very straightforward: open Files by Google and go to the cleanup section , where the system will show you various recommendation cards. One of these cards is called something like "Duplicate Files," and that's where you can review and delete repeated images.

Within this card, you can tap the " Select files" option . You'll see the photos grouped into sets, making it easy to identify which is the original (with its corresponding badge) and which are the copies that are unnecessarily taking up space on your Android phone.

Once you've decided which items you want to remove, select the photos by checking their boxes and, from the bottom of the screen, use the option to move the selected files to the trash . Files will display a confirmation message, usually indicating the total number of files you're sending to the trash, to ensure you're not deleting anything by mistake.

After that final confirmation, Files by Google moves the copies to the trash and frees up the corresponding storage space . For a while, you can still recover those files from the trash if you change your mind, but after that period they are permanently deleted from your device.

In short, Files by Google provides a fairly secure cleanup: it recognizes the original, highlights it, and encourages you to keep it , while deleting the copies you don't really need. It's ideal if you want to do it quickly without getting bogged down in too many advanced options.

Remove duplicate photos with Remo Duplicate Photos Remover

If you're looking for a more specialized tool, one of the most highly recommended apps is Remo Duplicate Photos Remover . It's free, almost entirely translated into Spanish, and focuses exclusively on one goal: detecting and deleting duplicate or very similar photos stored on your Android phone.

Remo's biggest advantage is that it performs a deep scan of your gallery . It doesn't just check the file name or size, but compares the image content, allowing it to find even similar photos that might otherwise go unnoticed . This includes burst shots, photos taken just milliseconds apart, or nearly identical versions with slight variations.

Upon opening the application, its use is quite intuitive: you'll see a main button to start scanning . Press it, and Remo begins analyzing all the photos it finds on the device. The first phase focuses primarily on images that are exactly identical , meaning they are the same file duplicated in different locations or repeated copies without changes.

This initial scan is usually quite quick, as it only compares identical files. Depending on the number of photos you have, it can be completed in about a minute on most current mobile phones, although if you have a very large gallery it might take a little longer.

Once it finishes, the app displays a very clear summary with the number of duplicate photos detected and the storage space they are occupying . From there, you can tap "accept" to go to the detailed list and see all the repeated images it has found grouped together.

Remo groups duplicates into sets, showing you different copies of the same scene in a single view . You can use the three-dot menu (the typical ⋮ menu) to automatically select all but one copy, or you can manually check the box next to each duplicate photo you want to delete.

Once you've made your selection, simply tap the trash can icon at the bottom of the screen. The app will ask you to confirm that you want to delete the selected files , and once you accept, it will remove all those identical photos that were just taking up space from your phone.

Search for very similar and repeated photos with Rowing

In addition to the mode for identical photos, Remo Duplicate Photos Remover includes a much more in-depth analysis to detect similar photos that aren't exactly the same . This is especially useful in cases where you've taken several photos in quick succession, tried different editing techniques, or cropped the same image with different apps.

To access this additional feature, within the app you'll find a section or tab called something like "Similar" or "Similar Photos ." Once there, you'll see a button to start the search process, usually labeled "Scan Now" or something similar, which begins a deep scan for similar images.

In this mode, the app takes its time, as it has to review and compare all the photos in much greater detail . In fact, it can take considerably longer than a simple duplicate analysis, especially if you have thousands of photos stored on your phone or SD card. It's best to do this with your phone charging or, at least, with a good battery.

Once the analysis is complete, Remo shows you similar photos grouped into sets . Within each group, you'll see several images that essentially represent the same scene: slight changes in framing, a subtle blur in one, a filter applied to another, and so on. From there, you can decide which ones you want to keep and which ones can be discarded without remorse.

It's important to understand that, in this mode, the photos aren't identical, but very similar . Therefore, it's recommended to take a few minutes to carefully review each group to ensure you don't delete the version you're most interested in (perhaps the one that came out in better focus, the one with better exposure, or the one you used on social media).

Once you've selected the unnecessary copies in each set, the process is the same as before: tap the delete button, confirm, and let the app erase all those duplicate photos . The space you free up can be considerable if you often take a lot of photos in burst mode or if you frequently edit the same image multiple times.

Other “Duplicate Photo Remover” apps for Android

Besides Remo, there are many apps on Google Play with names like "Duplicate Photo Remover," "Duplicate Photos Cleaner," and similar. They all have a very similar purpose: to scan your device's memory, locate duplicate or similar photos, and help you delete them quickly.

These apps are generally quite simple to use. When you launch them, they usually offer a large button to scan your phone for duplicate photos . After the scan, they display the results grouped into sets, so you can see all the copies of the same image in a single block.

Almost all of them include options to preview each photo before deleting it , review its details (size, resolution, folder location), and, of course, select one or more copies to send to the trash. This way, you can control at all times what is being deleted and what remains in your gallery.

One thing to keep in mind is that not all of these apps work equally well with similar photos . Some focus only on exact duplicates, while others try to detect nearly identical images. It's worth trying them out, checking user reviews, and making sure they aren't too aggressive in suggesting what to delete.

In any case, these types of apps are designed so that, in just a few taps, you can find and delete most of the duplicate photos that have accumulated over time. If you combine their use with official tools like Files by Google or Google Photos, your gallery will be much more organized.

Remove duplicate photos with Google Photos

Another very useful way to free up space on your phone, especially if you use cloud backups, is to take advantage of Google Photos . Although this app doesn't have a specific "delete duplicates" button, it does include automatic tools that help prevent duplicate photos and free up device memory.

Google Photos manages all the multimedia content associated with your Google account: photos, videos, albums, memories, facial recognition, smart search, and many other features. One of the most interesting for our purposes is the option to free up space when images are already backed up to the cloud.

The trick here is that, if you have backups enabled on your Google account, many of the photos you see in your Google Photos gallery are stored both on your phone and on Google's servers . This means you can delete the local copy from your device without losing the photo, because it will still be accessible in the cloud when you have an internet connection.

To use this option, open the Google Photos app and scroll down to the Library section . There you'll find a tools section, usually called "Utilities" or something similar, which groups together various automatic functions, such as creating collages, animations, and, most importantly for us, managing storage space.

Within Utilities, if you scroll down, you'll see a tool called something like "Free up space ." When you tap it, the app will tell you how many megabytes or gigabytes you can free up on your device by deleting photos and videos that are already backed up to the cloud. Just tap the button to confirm and allow it when prompted.

After that step, Google Photos removes the images and videos backed up to the cloud from your phone's internal storage, freeing up that space. It's important to know that you're not losing your photos; they're simply kept online and don't take up space on your local storage.

If you haven't enabled backups or haven't uploaded any photos yet, this "Free up space" feature won't appear or won't have any content to delete. In that case, before using it, you'll need to configure photo backups in your Google account , choosing the upload quality and the network you want to use.

How to get the most out of the Gallery app on Samsung phones

If you have a Samsung Galaxy phone, you have a very interesting extra feature: the Samsung Gallery app . Besides organizing your albums and offering different views, this app includes a suggestion system that, among other things, can detect duplicate images and suggest cleaning them up.

Unlike Google Photos, which is available for virtually any Android device, Samsung's Gallery app is exclusive to Samsung phones. This means you can only take advantage of its specific duplicate removal features if your device belongs to the Galaxy family.

To access the recommendations, first open the Gallery app and you'll usually see a menu icon in one of the corners, often in the bottom right. From there you can access a suggestions section , where the app analyzes your content and shows you possible actions to free up space.

Among these suggestions, you'll often find an option called something like "Remove duplicate images" within a cleaning or organizing section. Selecting it will display a list of duplicate photos the app has detected, with the option to select all copies or review each one in more detail.

Samsung Gallery lets you, for example, tap "Delete Duplicates" to automatically select all copies and keep the originals . For more precise control, you can also deselect photos you want to keep by tapping the corresponding circle next to each image in the list.

Once you're happy with your selection, simply tap the delete button at the bottom and confirm sending the images to the trash. This will remove the duplicate images from your gallery, freeing up space on your phone, while the originals remain safe.

Safety tips before deleting duplicate photos

While these tools are very useful, it's wise to be careful not to accidentally delete important photos or versions you really want to keep . A small oversight could cause you to delete the best shot from a series or the only copy of a valuable image.

Before performing a massive cleanup, consider activating or checking your cloud backup, whether with Google Photos, Samsung Cloud, or other services . This way, even if you accidentally delete something from internal storage, you'll have an additional chance of recovering it, provided it was previously backed up.

Another very practical tip is to always check groups of similar photos with your own eyes , especially when apps show you sets of similar but not identical images. Taking a few seconds to compare can save you regrets later.

It's also advisable, when using third-party applications like Remo or any "duplicate photo remover," to read the settings and confirmation messages . This will help you understand whether the files go to an internal recycle bin, are deleted directly, or if some kind of backup is created.

Finally, although it might be a hassle, it's helpful to occasionally disable automatic image downloads in messaging apps , or at least limit them to Wi-Fi networks. This will reduce the number of photos downloaded without your knowledge and prevent you from accumulating piles of duplicates simply by forwarding the same content repeatedly.

With all these tools and recommendations, keeping duplicate photos under control on Android is much easier. By combining Files by Google, Google Photos, your phone's native features (like Samsung's Gallery app), and specialized apps like Remo , you can reclaim a considerable amount of space, slightly speed up your device's performance, and, incidentally, have a much more organized gallery without having to manually review each photo.
