Resizing a signature for online forms

Online forms, especially exam and government applications, often ask for your signature as an image at an exact pixel size, and sometimes within a file-size limit as well. Scan or photograph your signature and it is almost never the size the form wants. This page resizes it to the exact pixels you need. Upload your signature image, set the width and height (or pick a common size), and download it. Fit mode keeps the whole signature inside the frame without cropping any of it, so none of the strokes are cut off. It all runs in your browser, so your signature is never uploaded. A signature upload usually has two requirements: the pixel size and, often, a maximum file size in KB. This page handles the pixel size. If your form also caps the file size, resize here and then compress the result, which lowers the KB without changing the dimensions. If your scan has a lot of white space around the signature, crop it tight first so it fills the frame.

Frequently asked questions

How do I resize my signature for a form?
Upload your signature image, set the width and height the form asks for (or pick a common size), and download it at exactly those pixels. It is free and runs entirely in your browser.
What size should a signature be for an online form?
It depends on the form, so check its instructions. Many ask for a small landscape image such as 140 × 60 pixels, but the exact size varies. Type the size your form specifies and the tool resizes to it precisely.
Will it cut off part of my signature?
No. Fit mode keeps your whole signature inside the frame and pads any extra space, so no strokes are cropped. If there is a lot of blank space around it, crop it tight first. Crop the signature first
My form also has a file-size limit in KB.
Resize to the right pixels here, then reduce the file size with our Compress tool. We have ready-made targets for the common signature limits of 10 KB and 20 KB. Compress signature to 10 KB
Can it keep a transparent background?
Yes. If you upload a transparent PNG signature and keep the output format as is, the transparent area is preserved. A signature scanned on white paper stays on white.
Is my signature private?
Yes. It is resized in your browser and never uploaded, so your signature stays on your device.
