Image files commonly include [Exif](https://en.wikipedia.org/wiki/Exif) data. Photos sometimes even include GPS coordinates in the file metadata. ## Desktop ### MAT2
![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).

## Mobile ### ExifEraser (Android)
![ExifEraser logo](assets/img/data-redaction/exiferaser.svg){ align=right } **ExifEraser** is a modern, permissionless image metadata erasing application for Android. It currently supports JPEG, PNG and WebP files. [:octicons-repo-16: Repository](https://github.com/Tommy-Geenexus/exif-eraser){ .md-button .md-button--primary } [:octicons-info-16:](https://github.com/Tommy-Geenexus/exif-eraser#readme){ .card-link title=Documentation} [:octicons-code-16:](https://github.com/Tommy-Geenexus/exif-eraser){ .card-link title="Source Code" }

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. ### Metapho (iOS)
![Metapho logo](assets/img/data-redaction/metapho.jpg){ align=right } **Metapho** is a simple and clean viewer for photo metadata such as date, file name, size, camera model, shutter speed, and location.

Warning

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).
## Command-line ### ExifTool
