## Description

MiCompress adds one-click compression to your WordPress Media Library, powered by
the
 [micompress.com](https://micompress.com/?utm_source=wordpress&utm_medium=plugin&utm_campaign=extend)
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](https://micompress.com/compress-jpeg?utm_source=wordpress&utm_medium=plugin&utm_campaign=extend),
[PNG](https://micompress.com/compress-png?utm_source=wordpress&utm_medium=plugin&utm_campaign=extend),
WebP, GIF, AVIF, TIFF, SVG, [PDF](https://micompress.com/compress-pdf?utm_source=wordpress&utm_medium=plugin&utm_campaign=extend),
DOCX/XLSX/PPTX, MP4, MP3, ZIP and more.

Curious how much each format shrinks? See the [compression benchmark](https://micompress.com/compression-benchmark?utm_source=wordpress&utm_medium=plugin&utm_campaign=extend),
built from thousands of real compressions.

### 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 from `https://micompress.com/downloads/…`.

## Installation

 1. Upload the `micompress` folder to `/wp-content/plugins/`, or install via the Plugins
    screen.
 2. Activate the plugin.
 3. (Optional) Choose a preset under **Settings  MiCompress**.
 4. Go to **Media**, and use the _Compress with MiCompress_ row or bulk action.

## 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.
