分享檔案時，請務必移除相關的中繼資料。 映像文件通常包含 [Exif](https://en.wikipedia.org/wiki/Exif) 數據。 照片有時甚至在文件元數據中包含GPS坐標。

**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 Nautilus](https://0xacab.org/jvoisin/mat2/-/tree/master/nautilus), the default file manager of [GNOME](https://www.gnome.org), and [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).

被清除的元資料取決於影像的檔案類型：
|
|||
|
|
|
|||
|
|
* **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.
|
|||
|
|
|
|||
|
|
處理完影像後， ExifEraser會為您提供一份完整的報告，說明每張影像中究竟刪除了哪些內容。
|
|||
|
|
|
|||
|
|
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.

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).

**ExifTool** is the original perl library and command-line application for reading, writing, and editing meta information (Exif, IPTC, XMP, and more) in a wide variety of file formats (JPEG, TIFF, PNG, PDF, RAW, and more).
|
|||
|
|
|
|||
|
|
It's often a component of other Exif removal applications and is in most Linux distribution repositories.

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.
