Description
MiCompress adds one-click compression to your WordPress Media Library, powered by the
micompress.com
engine (mozjpeg, pngquant, gifski, Ghostscript and more).
- Row action — hover any image or PDF and click Compress with MiCompress.
- Bulk action — select several items and compress them in one go.
- Presets — Lossless, Recommended or Extreme (Settings MiCompress).
- Files are only replaced when the compressed version is actually smaller; thumbnails are regenerated.
Supported: JPEG, PNG, WebP, GIF, AVIF, TIFF, SVG, PDF, DOCX/XLSX/PPTX, MP4, MP3, ZIP and more.

External services
This plugin relies on the MiCompress compression service (micompress.com), operated by MiCompress.
It is needed to compress files: compression happens on the service, not on your server.
- What is sent: the selected Media Library file (its contents and file name) and the chosen preset.
Nothing else — no site URL, user data or analytics. - When: only when an administrator clicks Compress with MiCompress (row action) or runs the bulk action.
The plugin makes no requests in the background. - Where:
https://micompress.com/<category>-compressors/compress; the compressed result is then
downloaded fromhttps://micompress.com/downloads/….

FAQ
-
Where are my files processed?
-
Files are sent over HTTPS to micompress.com for compression and the optimized version is
returned. Anonymous use is supported within per-type size limits. -
Does it keep a backup?
-
No. The attachment file is replaced in place only when the compressed result is smaller.
Keep your own backups if required. -
Why is the file replaced in place instead of saved as a new file?
-
So that the attachment keeps its file name and URL: every post, page or link that already embeds
it keeps working and immediately serves the smaller file. Only files inside the uploads directory
are written, through the WordPress Filesystem API.
