Adding a signature from a photo
If you already have your signature on paper, sign on plain white paper with a dark pen, take a straight, well-lit photo and choose it on the Upload tab. The tool turns the paper transparent and crops to the ink, so it looks natural on the page. Shadows and creases can leave marks, so if you see any, drag the background slider until they disappear or retake the photo near a window.
Signing on a phone or tablet
The page works on touch screens. Draw your signature with a finger or stylus, tap the page to place it and drag it into position. Rotated pages are handled too, so a scanned landscape form is signed the right way up.
Dates, initials and text
- Dates can be written as 10 November 2026, 10/11/2026, 11/10/2026, 2026-11-10 or Nov 10, 2026. Pick the one the form uses, because day-first and month-first are easy to mix up.
- Initials can be placed once or added to every page in one click, which suits contracts that ask for initials on each page.
- Text boxes are useful for a place, a title or a reference number next to your signature.
What ends up in the signed PDF
- Your signature and initials are added as PNG images at high resolution, so they stay sharp when you zoom in or print.
- Dates and text boxes are real, selectable text in the standard Helvetica font.
- Your original pages are not re-rendered or flattened into pictures. Their text, images and links stay as they were, and the new items are added on top.
- The file is saved as a new copy named after your PDF with
-signedadded, so the original is untouched.
What this does not do
This adds an electronic signature image to the PDF. It is not a certificate-based digital signature such as a DSC or Aadhaar eSign, which some legal and government filings require. It also does not verify who signed, add an audit trail or lock the document against later edits. If the person asking for your signature names a specific method, such as a DSC, Aadhaar eSign or a particular e-signature service, use that method instead. See electronic vs digital signature for the differences.
Questions
How do I add a signature to a PDF for free?
Open your PDF here, create a signature by drawing, typing or uploading a photo, click the page to place it and download the signed copy. It is free, needs no account and adds no watermark.
How do I add a signature to a PDF from a photo?
Choose the Upload tab, pick a photo of your signature on white paper and adjust the clean-up slider until the background disappears. Then click Use this signature and place it on the page.
Can I add my signature to every page?
Initials can be added to every page in one click. For a full signature, choose Signature again and click each page where it is needed.
Will the signature look blurry in the PDF?
No. It is added as a high-resolution PNG image cropped to the ink, so it stays sharp when zoomed or printed.
Does the person I send it to see an official signature?
They see your signature as a picture on the page. It is an electronic signature, not a certificate-based digital signature, so it does not carry proof of identity inside the file.
