How to use Resize Signature

  1. Sign on plain white paper with a dark pen and take a sharp photo in good light.
  2. Upload the photo and enter the width, height and maximum KB your form asks for.
  3. Keep "Clean background" on to make the paper pure white and the ink clear.
  4. Press Create signature, check the preview and download.

Why use Morfily Resize Signature?

Online applications for jobs, admissions and government services often reject signatures that are too large, have a grey background or the wrong size. This tool fixes all three in one step.

The signature is trimmed, centered and placed on a clean white background, then compressed to stay under your KB limit.

Frequently asked questions

What size should my signature be?

Use exactly what your form says. Common requirements are around 300×80 to 400×200 pixels and 10–50 KB.

My signature looks faint. What can I do?

Choose "Black" ink color, and take the photo in brighter light with a darker pen.

Why is there white space around my signature?

With "Keep proportions" on, the signature is not stretched, so white space fills the rest of the size. Turn it off to fill the whole area.

Is my signature uploaded or saved?

No. Everything happens on your device and nothing is stored.
