How to use signature resizer

01
Choose the signature scan stored on your device.
02
Check the dimensions and file-size limit against your portal’s instructions, then adjust the crop.
03
Select Prepare image, review Application Check and download the result.

Understand your requirements

Whitespace can make a signature appear tiny after resizing. Trim the margins first, then use Fit to place the entire signature on a white canvas. Compare thin strokes at the final size; a valid file can still need a clearer source.

Good to know

What does signature resizer check?

The exported file is decoded again to check its actual pixels, format, aspect ratio and byte size against your selected requirements.

Does READY TO UPLOAD guarantee acceptance?

It confirms the technical requirements you selected. The portal may also check identity, lighting, pose, background or document-specific rules; compare its current instructions yourself.
