Frequently asked questions
How do I resize my signature for an online form?
Upload a scan or photo of your signature, set the size, and download. The paper background is removed and transparency is kept.
What size should a signature be for a form?
It varies by authority and cycle. Check the current form for its format, KB band and any published dimensions before resizing.
How do I make my signature 10KB or 20KB?
Use the signature-to-20KB tool, which compresses to the cap while keeping a transparent background.
How do I resize a signature for UPSC or SSC?
Current UPSC instructions request one 20–100 KB JPG containing three signatures vertically. The cited SSC notice requests a separate 10–20 KB JPG/JPEG signature at about 6.0×2.0 cm. Confirm your exam notice before use.
What are the signature dimensions in pixels for forms?
Use pixel dimensions only when the current authority source publishes them. Several portals publish a KB band or physical size but no fixed pixels.
How do I get a transparent signature?
The tool lifts the paper background and exports a transparent PNG so it sits cleanly on documents.
How do I scan my signature for a form?
Sign on plain white paper, photograph or scan it in good light, then upload, and we clean it up.
Can I resize my signature on my phone?
Yes, photograph your signature and process it directly in the mobile browser.
How do I remove the background from a signature?
Use the signature background-removal tool or the transparent option to drop the paper.
Why won't my signature upload?
Compare the actual encoded format, KB band and any published dimensions with the current field. A transparent PNG will not satisfy a field that requests JPG/JPEG.
What format should a signature be, PNG or JPG?
Use the format requested by the destination. PNG preserves transparency for overlays; many exam portals instead request JPG/JPEG on a white field.
How do I crop my signature?
The signature crop tool auto-trims the empty space around the ink.
Is the signature resizer free?
Yes, free with no watermark.
Is my signature uploaded anywhere?
No, it's processed on your device only.
How do I make my signature clearer or darker?
Increase the background-removal strength to lift the paper and sharpen the ink.
Can I resize a signature without losing quality?
Yes. For ink on paper, trimming and light compression keep it crisp.
