About the Signature Resizer tool
Online applications for jobs, exams, banks and government services often ask for a scanned signature at a fixed size, such as 140 × 60 pixels, and a small file size. This tool crops your signature and resizes it to the exact pixels you choose, saved as a JPG that every form accepts. If your form gives a size that isn't listed, pick the one with the closest shape and check the form's instructions.

Frequently asked questions
What size should my signature be?
Follow your form's instructions. Many forms ask for a wide image, such as 140 × 60 pixels, with a file size of 10–20 KB. If yours gives a different size, pick the preset with the closest shape.
How do I get the file under 20 KB?
After downloading, open Compress Image to 20KB or Compress Image to 10KB and choose your signature file.
How do I get a clean signature?
Use a black or dark blue pen on white paper, take the photo in daylight without shadows, and keep the box close around your signature so there's little empty space.
Is my signature safe?
Yes. Your signature is processed in your browser and never uploaded, so nobody else can see or copy it.
