Compress an image to 50KB
Reduce any photo to under 50KB in a couple of seconds. This is one of the strictest limits you will encounter, and the tool is preset to hit it exactly.

Compression happens inside your browser, so even large photos are never uploaded.

Getting under a very tight limit
A 50KB ceiling is severe for a photograph. It appears most often on older government examination portals, where signature and photograph uploads are capped aggressively. Expect visible quality loss on a detailed photo — that is the nature of the limit, not a fault in the tool.
Get a better result by resizing first
The single most effective trick for a tight limit is to reduce the pixel dimensions before compressing. A 4000-pixel-wide photo squeezed into 50KB looks far worse than the same photo resized to 600 pixels wide and then compressed, because the smaller version has far fewer pixels competing for the same data budget. Use our image resizer first, then come back here.
Frequently asked questions
Why does my photo look blurry at 50KB?
There is only so much information that fits in 50KB. If the image still needs to be recognisable, reduce its pixel dimensions first — a smaller image at 50KB looks considerably sharper than a large one squeezed to the same size.
Is 50KB enough for a signature scan?
Yes, easily. Signatures are mostly white space with thin dark lines, which compresses extremely efficiently. Signature uploads are usually well under 50KB without any visible loss at all.
