Why 50 KB?
50 KB is one of the strictest file-size limits enforced anywhere on the web, and it's surprisingly common. Government exam application portals across India — including UPSC Civil Services, SSC CGL, IBPS bank exams, state PSC tests, and railway recruitment (RRB) applications — typically require candidate photos and signatures under 50 KB. The same limit appears on many university admission portals, scholarship forms, and older government employment websites.
Outside of exam portals, several visa and immigration application systems used by smaller jurisdictions still cap photo uploads at 50 KB, and a handful of public-sector job portals enforce the same limit on scanned documents. The constraint usually exists because the form was designed years ago for low-bandwidth users and was never updated.
Common use cases
- Indian government exam photo and signature uploads (UPSC, SSC, IBPS, RRB, state PSCs)
- University and scholarship application portals
- Older immigration and visa form attachments
- Public-sector recruitment portals with strict bandwidth limits
Tips for compressing to 50 KB
- For a passport-style photo, start from a 600×600 or smaller source — high-resolution camera photos will need aggressive compression to hit 50 KB.
- Choose JPG output for photos; PNG is rarely worth using at this size unless the original is a scanned signature with sharp edges.
- If 50 KB destroys quality, try 80 KB or 100 KB first and re-read the form — some portals state 50 KB as a recommendation, not a hard limit.
Frequently asked questions
How do I compress an image to 50 KB?
Drop your image into the tool above. It compresses automatically using JPEG quality reduction (and dimension scaling if needed). Nothing is uploaded — everything runs in your browser.
Does compressing to 50 KB reduce quality?
Some quality reduction is unavoidable when targeting small sizes. The tool uses a binary search to find the highest possible quality that fits under your target. For most photos at 50 KB, the result looks identical at normal viewing sizes.
Is this safe? Where do my photos go?
Your photos never leave your device. Compression runs entirely in your browser using the Canvas API in a Web Worker. There is no server upload, no storage, no logging.
Can I compress PNG to JPG to save space?
Yes — choose JPG in the output format selector. JPG compresses photos far more efficiently than PNG. Keep PNG only if your image has sharp text, line art, or transparency.
