Frequently asked questions

How do I get my photo under 50 KB without ruining it?

Don't guess with quality sliders. This tool automatically finds the highest quality (and, if needed, the largest dimensions) that still fits 50 KB — the result is the best-looking image that passes the limit.

Is my photo uploaded to your server?

No. Compression happens entirely inside your browser using its built-in image engine. Your photo never leaves your device — there is nothing to upload, and nothing for us to store.

What formats can I compress?

JPG, PNG and WebP input. Output is JPG (works everywhere) or WebP (smaller, supported by all modern browsers and portals). PNG output isn't offered because PNG can't hit small size targets for photos.

Need a different image size?

Every limit below uses the same tool with a different target, so you can go straight to the one your form or inbox actually asks for. If you only need a smaller file size in general and no exact number, pick the next limit up from where you are now and keep more quality.

Not sure which limit you need, or want to type an exact number of your own? The image compressor takes any target you give it.

The 50 KB sweet spot for form photos

50 KB is the classic passport-size photo limit. You'll see it on visa applications, and on competitive-exam and recruitment portals — SSC, UPSC, banking and railway forms in particular tend to cap the candidate photo at exactly 50 KB. It's tight enough to force real compression but generous enough that a properly cropped headshot still looks clean.

What quality to expect

A standard passport-style headshot fits comfortably into 50 KB with good clarity, provided it's cropped to the face and shoulders rather than left as a full-scene photo. The tool finds the best JPEG quality under the cap automatically; for most portrait photos that lands in a range where skin tones and edges stay smooth and natural.

Getting an accepted photo the first time

Match the required proportions. Most exam portals want a roughly 3.5×4.5 cm ratio — crop to that before compressing so the tool spends its quality budget only on pixels you'll keep.
Use even, front-on lighting. Harsh shadows add detail that eats file size and often fails photo checks.
Watch the minimum too. Some forms demand between, say, 20 KB and 50 KB. If yours has a floor, don't compress below it — aim just under the ceiling.

Choose the 50 KB preset above. If your form pairs a 50 KB photo with a smaller signature, the 20 KB tool handles that half.
