This places an image of your signature on the PDF: an electronic signature, not a certificate (digital) signature. Fine for everyday forms and agreements; for documents that legally need a DSC, Aadhaar eSign or a certified signature, use a licensed provider.

How it works
Your browser does the work
When you add a PDF, two open-source libraries stored on this site (pdf.js and pdf-lib, both openly licensed) read it on your device. Your signature is drawn, typed or cleaned from a photo into a transparent image, placed on the page, and written into a new copy of the file by pdf-lib. The original pages are copied as they are, never re-rendered, so nothing loses quality. Before the download is offered, the finished file is opened again and the signed pages are shown to you above, rendered from the actual output. If you tick "Keep my signature on this device", the signature image is kept in this browser's local storage only; nothing about it is sent anywhere, and the Delete link removes it.
Guide
Common jobs
- Everyday forms: permission slips, HR and bank forms, rental paperwork. Make the signature once, place it, check the preview, download.
- Initials on every page: add an Initials stamp, select it, and tick "Put on every page". It lands in the same spot on all pages; drag it to the corner contracts use.
- Signature photo came out grey: in the Photo tab, raise the cleanup strength until the paper disappears on the checkerboard, and prefer a dark pen on plain white paper in even light.
- Portal wants a small signature JPG: use "Your signature as an image" on the right: set the KB cap your portal states and download the JPG.
- Already digitally signed: if the warning appears, stop. Signing here rebuilds the file and invalidates the existing digital signature.
Questions
Is this a digital (certificate) signature?
No. This tool places an image of your signature on the PDF. That is an electronic signature: fine for everyday forms, letters and agreements where a signed copy is accepted. It is not a certificate (digital) signature: it carries no cryptographic proof of who signed or whether the file changed afterwards. For documents that legally require a certified signature, in India anything needing a DSC or Aadhaar eSign, and excluded documents like wills and property sale contracts, use a licensed provider.
Are my documents uploaded anywhere?
No. Signing happens in your browser, on your device. There is no server receiving your documents, which you can verify by loading this page, going offline, and signing a PDF anyway.
What if my PDF is already digitally signed?
This tool checks for an existing digital signature and warns you before you save. Saving a signed copy rebuilds the file, which would invalidate the digital signature already on it, so you can cancel instead of destroying it by accident.
Can it open a password-protected PDF?
No. A protected PDF cannot be read without its password, and this tool has no way to ask for one. To sign a protected file, open it in your browser with the password, then use Print and Save as PDF to make an unprotected copy, and sign that copy instead.
