Resize a signature to 10KB–20KB
Signature uploads for exam and banking forms usually specify both a pixel size (e.g. 140×60px) and a tight KB range. This page opens the tool with target size mode at 20KB and the resize box ready for your exact dimensions.
Set the fit-within width/height to whatever the form specifies, then let target size mode hit 10–20KB automatically — adjust the KB field to the low end of your form's stated range if it gives an exact minimum as well as a maximum.
A scanned or photographed signature is mostly flat color, so it compresses very cleanly — 10–20KB is comfortably reachable at typical signature dimensions.
Crop first if your source photo shows the whole page: the built-in editor crops to just the signature before the resize and compression run.
Common uses for a signature at 10KB–20KB
A signature at a tight KB range comes up across several form types:
- Bank KYC forms that specify an exact signature pixel size and a tight KB range together.
- Exam-board signature uploads, submitted alongside a photo with its own separate pixel and KB rules.
- E-signature attachments for online applications needing a small, clean file rather than an exact pixel size.
A scanned or photographed signature is mostly flat color, so it reaches 10–20KB cleanly at typical signature dimensions — cropping to just the signature first with the built-in editor keeps the file even smaller.
What if my form gives a pixel size but no KB range?
Set the fit-within width and height to the exact pixel size your form states, then still turn on target size mode at a mid-range value like 15KB — a signature-style image lands comfortably inside almost any unstated KB range at that setting, and the achieved-size readout on the card lets you confirm it before you submit.
