How it works
We binary-search the optimal quality so your image lands just under 500KB with the best possible sharpness. At 500KB you can usually keep full resolution and excellent detail.
When 500KB matters
Many content systems, marketplaces, and forums cap uploads around 500KB. It's also a sweet spot for fast-loading hero images on the web. Need smaller? Pick 200KB or 100KB in the options.
Free forever, no strings
Squishpix is free with no login, no watermark, and no file limits. Because processing happens in your browser, we have no server costs to pass on to you. If it saves you time, you can support the project with a donation.
FAQ
Will 500KB look noticeably worse?
Rarely. For most photos 500KB is enough to keep near-original quality, especially at typical web resolutions. We always pick the highest quality that still fits the limit.
Can I compress several images to 500KB at once?
Yes. Drop multiple files and each is compressed to fit under 500KB, then you can download them all as a ZIP.
