Frequently asked questions
How do I make a 10KB to 20KB signature?
Choose your exam preset (or a custom KB range) and the tool compresses your signature into that exact KB band, e.g. 10KB–20KB.
What is auto-crop to ink?
It detects the dark strokes of your signature on the white paper and trims the blank margins automatically, so you don't have to hand-crop.
Which signature presets are included?
SSC, RRB, UPSC (140×60) and bank/IBPS presets, plus a custom size and KB option.
Does it work on mobile (Android & iPhone)?
Yes — it runs in any modern mobile browser, no app to install, and works the same on Android and iPhone.
Is it safe and private?
Yes. Your file is processed in your browser and never uploaded to any server, so nothing is stored or shared.
Do I need to sign up or pay?
No — it's completely free, with no signup, no watermark and no limits.

1 MB = 1024 KB. If a form asks for a photo "under 50 KB", it means 50 kilobytes — use the tool above to hit that exact size.
