How do I sign a PDF online without printing it?
Add the document to Lunyce, tap "My signature", draw or type it, drag it into place and add the date if needed, then download the signed PDF. It is an image of your handwritten signature, not a qualified electronic signature. The file stays on your device and is never uploaded; it is free, with no sign-up.
How to
- Add your PDF.
- Tap "My signature", draw it, then drag it into place.
- Start, then download the signed PDF.
Frequently asked questions
Is this signature legally valid?
It is an image of your handwritten signature, like a document signed then scanned. It is enough for many documents (quotes, approvals, letters), but it is not a qualified electronic signature: some organisations may require one.
Are my files uploaded to a server?
No. Processing happens entirely in your browser, on your device. No file is uploaded or stored. You can check: once the page has loaded, disconnect from the internet and the tool still works.
Is there a file size or number limit?
No. Since nothing goes through our servers, there is no quota. The only limit is your device's memory: a computer handles very large files more easily than a phone.
Is it really free?
Yes. No sign-up, no watermark added to your documents and no usage limit.
