Frequently asked questions
Can I upload an image of my signature?
Yes. Choose “Upload” and pick a PNG, JPG or WEBP photo or scan. PDFCart removes the paper background automatically so only the ink appears on your document.
How do I make my signature background transparent?
Keep “Remove background” switched on after uploading. If faint paper marks remain, move the Strength slider right; if parts of the ink disappear, move it left. The checkered preview shows exactly what will be transparent.
Is it safe to sign documents here?
Yes. Your PDF and signature are processed entirely in your browser and never uploaded.
Can I sign on my phone?
Yes. Draw your signature with your finger, then drag it into place.
Can I add my signature to every page?
Yes. Tick “Sign every page” to place it in the same spot on each page — handy for initials.
Is this a legally binding signature?
Simple electronic signatures like this are accepted for many everyday agreements in most countries, but requirements vary. Check what applies to your document.
