FAQ
Frequently asked questions
Is my signature uploaded anywhere when I resize it?
No. Your signature image is resized locally using the Canvas API in your browser. It never leaves your device.
Which preset sizes are included?
The tool includes common signature requirements: 140 x 60 px, 200 x 80 px, 300 x 100 px, and 600 x 200 px, plus a custom width/height option for any other requirement a form might specify.
Will my signature look stretched?
If your signature's original aspect ratio doesn't match the target preset, it will stretch slightly to fill the exact dimensions. Many forms require an exact pixel size regardless, so check whether your specific form allows padding or letterboxing instead if stretching is a concern.
Should I remove the background first?
If your form also requires a plain white or transparent background, use the Signature Background Remover tool before or after resizing.
