Forms often ask for a signature image between 10 and 20 KB at a specific size such as 140 × 60 px. Our resizer trims the paper around your signature automatically and cleans the background.
Sign with a dark pen on plain white paper and take the photo in good light for the crispest result.
Upload a photo or scan of your signature on white paper.
Crop tightly around the signature and optionally remove the white background.
Set the dimensions and target size (10KB, 20KB, 50KB or custom).
Choose JPG or PNG, preview and download.
Yes. Choose PNG and keep “Remove paper background” on. JPG always has a white background.
Turn on “Remove white background” and export as PNG. JPG doesn't support transparency, so the background is filled with white instead.
Sign with a dark blue or black pen on plain white paper and photograph it in good light. The cleanup option also increases contrast.
Requirements vary from form to form. Check the instructions of the portal you're uploading to for the exact pixels and KB limits.
