A 20 KB limit is common on government exam portals (UPSC, SSC and many state PSC application forms) that ask for a small, fast-loading photo or signature scan. This tool finds the exact quality and, if needed, the exact dimensions to land under 20 KB automatically.

Drag & drop files here, or
Up to 100 images, 25 MB each
JPG, PNG or WebP — drag it in or pick it from your phone's camera roll.
This page pre-selects the 20 KB chip so you don't have to hunt for it, but you can still switch to any other size.
You get the exact final size, dimensions and quality used — no guesswork, no repeated re-uploads to a form that keeps rejecting your file.
Most photo editors only let you drag a quality slider and re-export, hoping you land close enough. At 20 KB, a typical smartphone photo needs both a heavy quality cut and a real reduction in pixel dimensions — get either one slightly wrong and you are either over the limit or the photo turns to mush.
This tool automates that trial and error: it binary-searches the compression quality first, and only shrinks the dimensions if quality alone genuinely cannot reach 20 KB on your specific photo. That keeps the image as sharp as the limit allows.
If your source photo has a very high resolution (typical of modern phone cameras, often 3–4000 pixels wide), expect the output to be resized down to somewhere around 200–300 pixels wide to fit 20 KB — that is normal and matches what most exam portals expect for a thumbnail-sized photo, not a print-quality one.
If your form also enforces a minimum size (some say "between 10 KB and 20 KB"), use the optional minimum field so the tool won't compress harder than necessary once it is already under the cap.
Some quality loss is unavoidable at this size, especially for a high-resolution source photo. The tool picks the highest quality that still fits, so it is the best result achievable at 20 KB — not an arbitrary compression.
Yes — a scanned signature is usually simpler than a photo (mostly flat background and thin lines), so it typically reaches 20 KB with better visual quality than a photo of a face would.
Yes, exactly the same engine — this page just starts you with the 20 KB target already selected, since that is the most common size asked for on this kind of form.
JPG is the default output format here. If your form accepts WebP instead (rare, check the instructions), you can switch it in the tool.
