The metadata that is erased depends on the image's file type:

* **JPEG**: ICC Profile, Exif, Photoshop Image Resources and XMP/ExtendedXMP metadata will be erased if it exists.
* **PNG**: ICC Profile, Exif and XMP metadata will be erased if it exists.
* **WebP**: ICC Profile, Exif and XMP metadata will be erased if it exists.

After processing the images, ExifEraser provides you with a full report about what exactly was removed from each image.

The app offers multiple ways to erase metadata from images. 17.1 e 18.1 característica GrapheneOS por rede completa [randomização MAC](https://en.wikipedia.org/wiki/MAC_address#Randomization) opção, e [`ptrace_scope`](https://www.kernel.org/doc/html/latest/admin-guide/LSM/Yama.html) controlo, e reinicialização automática/Wi-Fi/Bluetooth [opções de timeout](https://grapheneos.org/features).

* You can share an image from another application with ExifEraser.
* Through the app itself, you can select a single image, multiple images at once, or even an entire directory.
* It features a "Camera" option, which uses your operating system's camera app to take a photo, and then it removes the metadata from it.
* It allows you to drag photos from another app into ExifEraser when they are both open in split-screen mode.
* Lastly, it allows you to paste an image from your clipboard.
