🖼Format preserved
PNG stays PNG. JPG stays JPG. WebP stays WebP. We use PHP GD library for real per-format compression — the same approach used by professional tools.
🎛Quality control
Slide from 10% (maximum compression) to 95% (near lossless). The quality setting applies differently per format — JPG and WebP are lossy, PNG uses lossless stream compression.
🗑️Instantly deleted
Your image is permanently deleted from our server the moment your download starts. We never store, view or share uploaded files.
🌐Better Core Web Vitals
Smaller images mean faster page loads, better LCP scores and higher Google rankings. Aim for under 200KB per image on your website.
Frequently asked questions
Does PNG compression reduce quality?
PNG uses lossless compression — the quality slider controls the compression level (how hard the algorithm works to find smaller representations), not image quality. A PNG compressed at any setting will look identical to the original. Typical size reduction is 20–50% depending on image content.
What quality setting should I use for JPG?
For web images, 75–85% gives 50–70% file size reduction with no visible quality difference on screen. For product photography or images you plan to print, use 88–92%. For thumbnails, 60–70% is fine.
Are my images uploaded to your server?
Yes — server-side compression is what allows PNG to stay PNG and JPG to stay JPG. Your image is uploaded over HTTPS, compressed in under a second, returned to you, and then permanently and automatically deleted. We have no system to store or view your files.
What happens to GIF and BMP files?
GIF is already internally compressed to its maximum — compression will have minimal effect. BMP has no compression at all, so we re-encode it as PNG which gives typically 60–80% smaller output while keeping identical quality.
Does compression change image dimensions?
No. Width and height are never changed — only the file size is reduced. To also resize dimensions, use our Image Resizer tool.
