FAQ
Signature 300 × 80: questions and answers
How do I resize my signature to 300 × 80 pixels?
Take a clear photo of your signature, add it on this page and download. The 300 × 80 px size is already set, and the signature is fitted whole on a white background so nothing is cut off.
My photo has lots of paper around the signature. Is that a problem?
The tool keeps the whole photo, so extra paper makes the signature small. Take the photo close to the signature, or crop it in your phone's gallery first, so the signature fills most of the picture.
What file size should a signature be?
Usually 10 KB to 50 KB. Under 20 KB is chosen here; if your form says something else, tap it or type the number in the Custom box.
Is my photo uploaded to a server?
No. The image is resized inside your web browser on your own device, so 0 bytes are uploaded and nothing is stored. It even works offline once the page has loaded.
