Frequently asked questions
Is my document uploaded to a server?
No — and for contracts, offer letters, and agreements that matters more than anywhere else. The document and your signature are processed entirely on your device; neither is transmitted, stored, or seen by anyone.
How do I create the signature?
Three ways: draw it with your mouse, finger, or stylus; type your name and pick a script, italic, or plain style; or upload an existing image — a PNG with a transparent background looks best, but a photo of your signature on white paper works too.
Can I place it exactly where the signature line is?
Yes — the signature appears as a draggable box on a live preview of the actual page. Drag it onto the signature line, adjust the size slider, and what you see is exactly what lands in the file.
Can I sign a specific page?
Yes — a thumbnail strip lets you jump to any page. Sign one page, download, and run it again if more pages need signatures.
Is this a legally binding e-signature?
The tool draws your signature into the PDF — the same as printing, signing, and scanning. Many everyday agreements accept that; for regulated use cases requiring certificate-based digital signatures or audit trails (like notarized documents), use a dedicated e-signature service.
Does it change the rest of the document?
No — the pages are untouched except for the signature image placed where you dropped it. Text stays selectable and quality is preserved.

You can sign, stamp and annotate a PDF with a photo from your phone
The tools that put a picture into a PDF — Sign, Watermark, Annotate, Edit and the signature maker — were the last holdouts still asking for a PNG or a JPG. So the obvious thing, photographing your signature on a piece of paper and uploading it, did not work from an iPhone, because an iPhone saves that photo as a HEIC. The file picker greyed it out and there was nothing on screen explaining why. All five now take any photo your phone produces, HEIC included, along with WebP, GIF, BMP, TIFF and AVIF. A signature with a transparent background stays transparent — we keep the see-through parts rather than flattening them onto a white box, which is the whole reason people export a signature as a PNG in the first place. If a picture genuinely cannot be opened, the message now says what the file turned out to be instead of just refusing.
