![MAT2 logo](assets/img/data-redaction/mat2.svg){ align=right }

**MAT2** is free software, which allows the metadata to be removed from image, audio, torrent, and document file types. It provides both a command line tool and a graphical user interface via an extension for [Dolphin](https://0xacab.org/jvoisin/mat2/-/tree/master/dolphin), the default file manager of [KDE](https://kde.org).

On Linux, a third-party graphical tool [Metadata Cleaner](https://gitlab.com/rmnvgr/metadata-cleaner) powered by MAT2 exists and is [available on Flathub](https://flathub.org/apps/details/fr.romainvigier.MetadataCleaner).

</div>

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.

<p class="admonition-title">Warning</p>

You should **never** use blur to redact [text in images](https://bishopfox.com/blog/unredacter-tool-never-pixelation). If you want to redact text in an image, draw a box over the text. For this, we suggest apps like [Pocket Paint](https://github.com/Catrobat/Paintroid).

## Criteria

**Please note we are not affiliated with any of the projects we recommend.** In addition to [our standard criteria](about/criteria.md), we have developed a clear set of requirements to allow us to provide objective recommendations. We suggest you familiarize yourself with this list before choosing to use a project, and conduct your own research to ensure it's the right choice for you.

<div class="admonition example" markdown>
<p class="admonition-title">This section is new</p>

We are working on establishing defined criteria for every section of our site, and this may be subject to change. If you have any questions about our criteria, please [ask on our forum](https://discuss.privacyguides.net/latest) and don't assume we didn't consider something when making our recommendations if it is not listed here. There are many factors considered and discussed when we recommend a project, and documenting every single one is a work-in-progress.
