How to Change the File Extension on Android Devices

Quick Tips

• You can easily change a file’s extension on your Android by renaming it.
• Use the default file manager app on your phone, such as Files by Google or Samsung My Files, to rename files.

Method 1: Change File Extension Using the Files by Google App

Most Android phones come with the Files by Google app as the default file manager, which offers several useful features for managing, sharing, and backing up files. Here’s how you can use it to change the file type (extension) on your Android phone.

Step 1: Open the Files by Google app. If you can’t find it, download it from the Play Store.

Step 2: Locate the file whose extension you wish to change. Tap the three-dot menu icon next to it and select Rename.

Step 3: Replace the existing file extension with a new, compatible one and tap OK. Then, tap Rename to confirm.

Method 2: Change File Extension Using the Samsung My Files App

If you have a Samsung Galaxy phone, you may be using the built-in My Files app to manage your files. In that case, you can use these steps to change a file’s type or extension on your Samsung Galaxy phone.

Step 1: Open the My Files app on your phone and navigate to the file whose extension you need to change.

Step 2: Long press on the file to select it. Tap the three-dot menu icon at the bottom and select Rename.

Step 3: Replace the extension with a new one and tap Rename. Then, tap Change to confirm.

Things to Keep in Mind While Changing the File Format or Extension on Android

• It’s important to note that changing the file extension by simply renaming the file can sometimes result in compatibility issues. For example, replacing the .pdf extension with .jpg doesn’t magically transform the file into an image.
• If you convert to a file type unsupported by the apps on your Android, the file may fail to open. In such cases, you may need to download an app capable of reading and opening that specific file type on your phone.
