50 KB is the sweet spot a lot of exam and admission portals ask for when they want a real photo — big enough for a recognisable head-and-shoulders shot, small enough to keep their servers light. It's also a comfortable ceiling for the small logo or signature image you paste into an email footer, where anything heavier slows every message down. This tool brings a JPG, PNG, or WebP under 50 KB right in your browser.

Set 50 KB as the target and the compressor reduces JPEG quality first, then trims pixel dimensions if the size is still over budget. Fifty kilobytes leaves a bit more room than the tightest 20 KB fields, so a portrait usually keeps clean skin tones and readable text without obvious blocky artefacts.

Everything happens on your device — nothing is uploaded — and there are no watermarks or account walls, so you can re-compress as many attempts as you need to match a portal's exact rule.
