Frequently asked questions
Why do forms ask for a 20KB photo or signature?
A 20KB cap keeps application servers fast and storage costs down when thousands of applicants upload photos at once — which is why it's such a common limit on Indian government recruitment portals, especially for signature uploads. SSC CGL, UPSC, IBPS bank exams, and several state PSC and railway recruitment forms specify a signature (and sometimes photo) size limit in this range, and uploads over the limit are simply rejected at submission.
The problem is that a photo straight off a phone camera is usually 2-5MB — 100-250x too large. Resizing dimensions alone doesn't reliably hit an exact KB target, which is what this tool does directly: pick 20KB, upload your photo or signature, and download a file sized right for the form.
How it works
Your photo is re-encoded to land at or under 20KB while keeping it sharp enough to pass photo-verification checks — no visible quality loss for a small ID-style or signature image. If you need a different size, the same tool supports custom targets like 50KB or 100KB too.
