About this image compressor
Most compressors shrink a photo and hope for the best. This image compressor is built around the exact file sizes that exam and job portals demand — 20 KB, 50 KB, 100 KB and the like — with a live readout as you drag the quality and size sliders, so you land inside the allowed range before you upload. It works on JPG, PNG and WebP images, and your photo is processed on your own device.

How do I compress an image to exactly 50 KB?
Add your image, then move the quality slider and watch the size readout. Nudge the slider until the size sits just under your target, then download. If quality alone is not enough, reduce the size (dimensions) slider a little as well.
Will my photo lose quality?
Compression always trades a little quality for size, but at form sizes like 20–100 KB a normal photo still looks clear. The live preview lets you check before you download.
Which image formats can I compress?
JPG, PNG and WebP. JPG is the best choice for most exam and form uploads.
Is there a limit on the image size?
The tool runs in your browser, so very large photos from high-end phones may take a few seconds. There is no upload, so there is no server limit either.
