About this plugin
PuffPix Compress automatically optimizes every image you upload to WordPress — reducing file sizes by 40–80% without visible quality loss. Faster pages, lower bandwidth, better Core Web Vitals scores.
It works by connecting to the PuffPix image compression API. When you upload an image, PuffPix compresses it server-side using industry-leading encoders (mozjpeg, pngquant, cwebp) and returns the optimized file, which replaces the original in your media library.
Why PuffPix?
- No server load — compression happens on PuffPix servers, not yours
- Better encoders than GD — mozjpeg and pngquant produce noticeably smaller files at the same visual quality compared to PHP’s built-in GD library
- All thumbnail sizes — automatically compresses every generated thumbnail, not just the original
- EXIF stripping — removes GPS coordinates and device metadata for privacy
- Bulk optimization — compress your entire existing media library in one click with a live progress log
- Per-image stats — see exactly how much each image was reduced, right in the media library
- Free trial — 100 compressions included, no credit card required
How does it compare?
Most WordPress image plugins use your server’s GD library or charge a premium for better encoders. PuffPix uses mozjpeg and pngquant on every plan — including free.
99/mo for unlimited use. 50/mo.
vs Imagify — Imagify’s free tier limits you to 20MB/month, which most sites burn through in one upload session. PuffPix gives 20 compressions/day with no data cap, and a 100-credit free trial to get started.
vs TinyPNG — TinyPNG charges per compression above 500 credits/month — costs spiral on busy sites. 50/mo with no per-image fees.
vs Smush — Smush Pro requires a WPMU Dev membership bundled with tools you may not need. PuffPix is a standalone plugin — pay only for image compression, nothing else.
io? PuffPix is a drop-in replacement — same concept (API-based compression, replaces files in your media library), actively maintained, with a free trial to get started.
Compression Engines
- Standard (GD) — PHP’s built-in image library. Fast and universally compatible. Quality 85 (balanced) or 72 (aggressive).
- Pro (mozjpeg + pngquant) — significantly better compression than GD at the same visual quality. JPEGs typically 20–30% smaller than GD output.
- Max — maximum compression using the best available encoder per format. Smallest possible file size. Requires Pro or Trial plan.
Supported Formats
JPEG, PNG, WebP, GIF. SVG compression is available on the PuffPix web tool.
Free Trial
New users get 100 free compressions that never expire — no credit card required. php.
