|

|
||
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. chú ý
|
||
|
||
* 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.
