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. Namely:
- 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.

Warning
You should never use blur to redact text in images. If you want to redact text in an image, draw a box over the text. For this, we suggest apps like Pocket Paint.
