A signature image is often too large or too dark when it is scanned straight from a document. This tool resizes it to a standard signature-friendly shape and keeps the process local.
The result is useful for forms, PDFs and signing workflows that need a compact, sharp image.
How to use this tool
- Upload the signature scan or photograph.
- Choose a preset such as a typical digital signature ratio or a custom width and height.
- Download the resized file with a crisp output ready for forms or documents.
Frequently asked questions
Can I make it smaller without losing legibility?
Yes. The tool lets you choose a precise size before downloading, and it keeps the signature readable by resizing the canvas rather than distorting the pixels.
Will it remove the background?
It only resizes the image. For a cleaner signature, use a white or transparent background before uploading if needed.
