Compress to 500 KB

Add an image to enable compression.

Compress an image to 500KB free, right in your browser. Half a megabyte is a common ceiling for email-friendly photos, blog images, newsletters and document attachments — big enough to keep a photo looking sharp, small enough that pages load fast and inboxes don't choke.

Drop an image in and the tool finds the highest JPEG quality that fits under 500KB — at this size, almost every photo keeps its full dimensions and looks indistinguishable from the original. The compression runs entirely on your device with nothing uploaded, so it's safe for personal photos and client work alike.

Frequently asked questions

Will a 500KB photo look different from the original?

Almost never on screen. 500KB is a generous budget — most photos fit at high JPEG quality with their full dimensions intact, so the compressed version looks identical to the original in normal viewing.

Why compress images to 500KB for email or a website?

Attachments and page images add up fast: five 5MB photos make a 25MB email that many providers reject, and slow every page they're on. At 500KB each, the same photos send instantly and pages stay quick, with no visible quality cost.

Are my photos uploaded?

No. Everything happens in your browser using the Canvas API — the image never leaves your device. Free to use, no sign-up, no watermarks.
