Compress a scanned or photographed signature toward a chosen KB size for forms. Runs in your browser.
Compresses a signature image toward a KB size that a form accepts. It keeps the largest result at or under your target when it can, otherwise the closest, and reports the achieved size.
JPG with a white background suits most forms. Choose PNG if you need the signature on a transparent background.
Your signature is processed on your device. Nothing is uploaded, and re-encoding strips EXIF and GPS metadata.
This tool compresses a scanned or photographed signature toward a chosen KB size, in your browser, so it fits a form upload limit without being sent anywhere.
It keeps the largest result at or under your target when it can, otherwise the closest, and reports the achieved size. For a clean look on forms, keep JPG with a white background, or switch to PNG when you need transparency.
Defaults to a small KB target and a white JPG background that suits most upload forms.
Keeps the largest result at or under your target when possible, and flags it as over target when the target is not reached.
Switch to PNG to keep a transparent signature instead of a white background.
Your signature stays on your device and is never uploaded.
Fit a signature under the KB limit on job, exam, and bank forms.
Prepare a small signature image for upload boxes.
Shrink a photographed or scanned signature for attachment.
Reuse one compressed signature across several forms.
No. It compresses toward your KB target and reports the size it actually reaches, keeping the largest result at or under target when it can.
Yes. Choose PNG output to keep transparency. JPG output fills any transparent areas with the background color you pick, usually white.
No. The signature is compressed in your browser, so the image never leaves your device.
Many forms ask for around 20 to 50 KB. Set the KB target to match the form, and the panel will show whether the result met it.
If the tool re-encodes the signature to reach your target, it strips EXIF and GPS metadata, which the panel notes. If the original is kept because it is already under target, its metadata is unchanged.
