Upload a JPG, PNG, or WebP above to compress it to 25KB — processed entirely in your browser, no upload to a server. 25KB sits between the 20KB limit common for signature scans and the 50KB limit common for passport-sized photographs on Indian government and exam portals.
25KB is most common on state government service portals and university registration systems. Some portals use it as the limit for photographs when they want something smaller than the 50KB standard but don't need the very tight 10–20KB limits used for signature images. You may also see it on ration card, voter ID correction, and birth certificate applications in certain states.
If your form shows a 20KB limit instead, use our 20KB compressor. If it shows 50KB, use our 50KB compressor — submitting a file that is slightly over the limit will cause the portal to reject the upload, even if the difference is just a few kilobytes.
For a passport-sized photograph (typically 150×200 to 300×400 pixels), 25KB allows moderate compression without obvious artefacts. The face will be clear; fine details like hair texture will show some softening. For official submission purposes, this is well within acceptable quality.
For a signature scan, 25KB is generous. A clean black-on-white signature at standard dimensions compresses to well under 25KB without any quality loss — so the tool may produce a file smaller than the target, which is fine. Portals check for maximum size, not minimum.
Many portals that set a 25KB limit also specify pixel dimensions — for example, 3.5 cm × 4.5 cm at 100 DPI, which works out to roughly 138×177 pixels. Compressing a 3000×4000 camera photo to 25KB requires very aggressive compression and the result will show artefacts. Crop and resize to the required pixel dimensions before compressing, and the tool will hit 25KB with far less quality loss.

The tool targets 25KB automatically. Done in a few seconds.
Verify the final file size before form submission. Some portals show a real-time size warning; others only tell you at submit time.
