Plenty of exam and government forms specify a signature box of exactly 50×20 mm — that's 5×2 cm, or roughly 591×236 px at 300 DPI. This tool resizes your scanned signature to that strip so it matches the form's signature field.
5pxThe resize runs in your browser, keeping your signature private while you size it for the upload.

- Keep 50×20 mm: The size is preset to 5×2 cm; switch units or numbers if your form differs.
- Resize: Scale the signature to the exact strip dimension.
- Download: Save the resized signature, then compress it if the form caps the file size.
