Are my images uploaded to a server?

No. OPTIMIZE IMAGE runs the entire compression inside your browser using the Canvas and Blob APIs. Your photo never leaves your device, so there is nothing for us to store, log or leak.

The result looks blurry — what now?

Crop the image smaller, or switch the output format to WebP. Both give the encoder more room to preserve detail within 50KB.

Is it really free and unlimited?

Yes. There is no sign-up, no watermark and no per-file limit. Because the work happens on your own device, there are no server costs to pass on to you.

Compress Image to 50KB

50KB is a strict limit, usually found on older government and exam portals. The tool below is preset to 50KB and will reduce dimensions automatically if quality alone is not enough.

Everything happens on your device, so you can experiment freely with formats and sizes.

Making 50KB look good

At this size, pixel count is your budget. A 400×500 crop at 70% quality looks far better than a 3000×4000 image squeezed to the same 50KB. Crop first, then compress.

When 50KB isn't achievable losslessly

PNG cannot usually reach 50KB for a photograph. The tool will report this honestly and suggest JPG or WebP output, or a smaller dimension.
