Description
JaziTech Image Compressor automatically compresses your images when you upload them to WordPress — no API key, no external service, no monthly fees. Everything happens on your own server using the PHP GD library.
Free features:
- Auto-compress on upload — JPEG, PNG and GIF files are compressed the moment they are uploaded, before WordPress generates thumbnails.
- Adjustable quality — set JPEG quality from 1 to 100 (default 82, a great balance of size and quality).
- Strip EXIF / metadata — remove embedded metadata from images for smaller files and more privacy.
- Backup originals — keep a backup copy of every original image and restore it any time from the Media Library.
- Bulk optimize — compress all existing images in your media library with AJAX batch processing and a live progress bar.
- Savings column — the Media Library shows original size, compressed size and percentage saved for every image.
- Max dimensions — optionally resize oversized images on upload.
Privacy: This plugin does not phone home. It sends no data anywhere — all compression happens locally on your server using PHP GD.
Want more? JaziTech Pro adds WebP & AVIF conversion, scheduled background optimization, unlimited priority bulk processing and a global image CDN. See Settings Go Pro inside the plugin.

FAQ
-
Will this work without an API key?
-
Yes. Unlike many image optimizers, this plugin compresses images locally on your server with PHP GD. No account, no API key, no usage limits.
-
Will it slow down my uploads?
-
Compression adds a fraction of a second per image on typical hosting. Bulk optimization processes images in small batches so it never times out.
-
Can I restore the original images?
-
Yes — if “Keep backup of originals” is enabled (the default), every original is backed up before compression. Use the “Restore original” link in the Media Library list.
-
Does it convert to WebP?
-
WebP and AVIF conversion are Pro features. The free version compresses JPEG, PNG and GIF in their original formats.
-
Does the plugin send my images anywhere?
-
No. All processing happens on your own server. The plugin makes zero external requests.
