Who needs a 50 KB signature?
A 10–50 KB signature at roughly 354×157 pixels (4.5×2cm at 200 DPI) is the specification used by PAN card applications through NSDL / Protean's e-Sign step. It is a wider window than the 10–20 KB used by SSC and IBPS exam forms, so a signature that already fits SSC's spec will comfortably fit here too. If your form uses a different portal, see the full signature resize tool for every preset and a per-portal spec table.
Resizing a signature to 50KB — FAQ
How do I resize my signature to under 50 KB?
Upload your signature photo, drag over it to crop out just the ink (cutting away the paper margin), and use the preset already loaded on this page — 354×157px, 10–50 KB. Download the JPEG when it finishes; the tool binary-searches the JPEG quality that lands inside that window without changing the pixel size.
What pixel size should a 50 KB signature be?
For PAN card applications through NSDL / Protean e-Sign, 354×157 pixels (about 4.5×2cm at 200 DPI) is the commonly cited signature box that pairs with a 10–50 KB file size. This page defaults to that combination — you can still type a different width, height or KB range if your form differs.
Why does NSDL reject signatures under 10 KB?
Very small file sizes usually mean the ink is faint or the scan is low-detail, which some portals treat as unreliable for verification. That is why NSDL enforces a floor as well as a ceiling. If your resized file lands under 10 KB even at high JPEG quality, the tool will tell you — try a higher-contrast scan (darker ink, brighter white paper) before resizing again.
Is my signature uploaded anywhere when I use this tool?
No. Cropping, resizing and compression all happen locally in your browser using canvas — the photo never leaves your device, and there is no account, storage or upload step.
