Browse and search collection.media to insert images into cards, replace or rename files across every reference, and find unused or duplicate media for recoverable cleanup.
Automatically converts and resizes pasted or dragged images to WebP or AVIF, bulk-converts existing media, renames files, and removes duplicate media.
Clones a deck and its subdecks in place, retaining media references but not tags, and deletes duplicate notes whose fields are completely identical.
Extracts and deduplicates inline CSS from selected note fields, moves it to a shared media file, then inserts import links—optionally handling repeated inline styles, base64 images and Yomitan media references—to shrink collections.
Displays byte sizes for the collection and individual notes, including attachments, and lets users sort notes by size and view deck or search-result sizes.
Downloads externally referenced images and audio from a selected deck into Anki's local storage and updates the notes' HTML and sound references.
Safely consolidate byte-for-byte identical files in Anki's collection.media folder.
Anki Media Deduplicator finds media files with exactly identical content, rewrites note references to one canonical filename, and moves redundant copies to Anki's trash through the official media API. It is designed especially for collections affected by AnkiDroid's historical temporary-file naming behavior.
_, and latex- files are protected.Important: Applying moves redundant files to Anki's media trash first; this alone does not free disk space. To actually reclaim the space, open Tools → Check Media and permanently delete the files from the media trash.
This add-on removes exact duplicate media. It does not replace Anki's Check Media feature for finding unused or missing files.
Anki 媒体去重会查找内容逐字节完全相同的媒体文件，将笔记中的引用统一改写为一个规范文件名，然后通过 Anki 官方媒体 API 把多余副本移入回收站。本插件主要用于处理受 AnkiDroid 历史临时文件命名行为影响的媒体库。
_ 开头的文件及 latex- 文件都会受到保护。重要： 应用去重只会先将多余媒体移入 Anki 回收站，不会立即释放磁盘空间。要真正释放空间，请打开 工具 → 检查媒体，在其中实际删除回收站里的媒体文件。
本插件处理的是内容完全相同的重复媒体，并不替代 Anki 自带的 检查媒体；后者用于查找未使用或缺失的媒体文件。

An Anki Desktop add-on that safely removes media files whose contents are exactly identical.
It is especially useful for collections affected by AnkiDroid imports that saved the same audio or image repeatedly under different filenames.
This add-on removes duplicate media. It does not replace Anki's Check Media tool, which finds unused or missing files.

Applying moves redundant files to Anki's media trash; this alone does not free disk space. To actually reclaim the space, open Tools → Check Media and permanently delete the files from the media trash.
The add-on does not run automatically and does not start a sync.
Files are verified again when you apply a scan result. If a file has changed or disappeared, its duplicate group is skipped. A canonical file is always made available and note references are migrated before redundant copies are trashed.
As with any tool that modifies a collection, make sure your collection has a current backup before applying changes. Files moved to Anki's media trash remain on disk until they are permanently deleted in Check Media.
