Frequently asked questions
What pixel size and file weight should a scanned signature have for Indian government exams?
Most Indian exam portals ask for a signature between 10 KB and 50 KB, but the pixel box varies. NEET, UGC NET, GATE, UPSC, BPSC, NDA, passport and visa forms want 200×100 px. SSC and TNPSC want 200×80 px. CAT asks for 150×75 px and RRB for 140×60 px. File-weight limits differ too: SSC is tightest at 10-20 KB, GATE is the most generous at 4-200 KB, and RRB and TNPSC cap at 40 KB. Sign on plain white paper, photograph it flat, then crop and compress in this tool to the dimensions listed above.
Do I need to upload my signature anywhere?
No. The resize, crop and compress steps run entirely inside your browser. The image is never sent to a server, so it stays on your own device throughout.
Is the tool free and does it need an account?
Yes on both counts. There is no charge, no login, no email verification and no watermark added to the final image.
Why does my uploaded signature look blurry after resizing?
Starting from a well-lit photograph taken straight above the signed paper keeps the source sharp. Crop close to the ink before resizing, because enlarging a small crop to fit 200×100 px or 140×60 px is what softens the strokes. Compressing once to the required file weight, rather than several times, also preserves edges.
