Key benefits
Signature aspect
Uses a wide 3.5×1.5 style ratio suited to form signature boxes.
20 KB ready
Target-size mode aims for the strict signature ceilings many portals use.
Private
Scans never leave your device.
Tips for clear signatures
Use high contrast, crop out blank margins, and prefer JPG. If 20 KB still fails, shrink width/height further or open Compress to 20 KB after cropping.
For face photos under 50 KB, use Passport Size Photo.
FAQ
Common questions
Why 140×60 pixels?
It is a compact digital size close to a small printed signature box. Change width and height if your form lists other dimensions.
What if the file stays above 20 KB?
Crop tighter, lower the pixel size, or allow resize-to-target. Thick ink scans need fewer pixels to fit tiny limits.
Is the signature uploaded?
No. Processing stays in your browser.
