Sign a PDF online without printing it
The routine this replaces is familiar and ridiculous: print the document, sign it with a pen, scan it back, end up with a 12 MB crooked grey photocopy. Signing directly on the page skips all of it and produces a clean, right sized file where the rest of the document is still sharp, selectable text.
Three ways to make the signature, suiting different situations. Drawing with a mouse, trackpad or finger gives the most natural result, especially on a phone or tablet where you can sign with your finger. Typing your name renders it in a handwriting style, which is quick and perfectly acceptable for routine paperwork. Uploading a photo of a signature on white paper is the option to choose when a form specifically needs your actual signature. Whichever you use, it is saved in your browser so the next document takes seconds.
It is worth being precise about what this is. A placed signature image is an electronic signature, and for most everyday agreements, consents, declarations, offer letters and office paperwork that is what is used and accepted. It is not a certificate based digital signature: it carries no cryptographic certificate binding your identity to the document. Where a DSC or Aadhaar eSign is specifically required, such as certain statutory filings and registrations, use the designated service for that.
Simple, practical guidance
How to use Sign PDF
Make your signature once, place it where it belongs, and save. The signature is stored on this device so the next document takes a few seconds rather than starting over.

Get a better result
The signature is drawn on top of the original pages, which are kept exactly as they were, so nothing is recompressed and form fields and bookmarks elsewhere in the document are preserved.
Know how your file is handled
Signing happens entirely in your browser, so neither the document nor your signature is uploaded. Your saved signature stays in this browser on this device.
Check before you share
This places a visible signature image on the page. It is not a certificate based digital signature, so it does not cryptographically prove who signed in the way a DSC or Aadhaar eSign does.
Questions people ask
Sign PDF FAQ
Creating a signature, legal weight, digital signatures, and signing on a phone.
How do I sign a PDF online?
Upload the document, create your signature by drawing, typing or uploading it, click where it should go on the page, adjust the size, then save and download the signed PDF.
Is an electronic signature like this legally valid?
For most everyday agreements, consents, declarations and office paperwork, electronic signatures are widely used and accepted. Specific statutory filings and registrations can require a certificate based digital signature instead, so check what the particular document demands.
Is this the same as a digital signature or DSC?
No. This places a visible signature on the page. A digital signature, such as a DSC or Aadhaar eSign, attaches a cryptographic certificate that proves who signed and that the file has not changed since. Where that is required, use the designated service.
Is my signature uploaded to your server?
No. Signing runs entirely in your browser, so neither the document nor the signature leaves your device. The saved signature is stored in this browser only.
Can I sign on my phone?
Yes, and a phone is often the best way to do it, because you can draw the signature with your finger and get a far more natural result than with a mouse.
How do I add the date or my initials?
Use the date and initials options alongside the signature. Many forms ask for initials on each page and a date beside the signature, and both can be placed wherever they are needed.
Can I upload a photo of my signature?
Yes. Sign on white paper, photograph it in good light and upload the image. This is the option to pick when a form specifically asks for your actual handwritten signature.
Can I draw the signature instead of uploading a photo?
Yes. There are three ways in: draw it with a mouse or a finger on a touchscreen, type your name and pick a handwriting style, or upload a photo of a signature you made on paper. Drawing is the quickest on a phone, and the result is trimmed to the ink so no white box sits around it.
Will the rest of the document stay unchanged?
Yes. The signature is added as a layer on top, so the original pages are copied across untouched and nothing elsewhere in the document is recompressed or altered.
Can I sign a password-protected PDF?
Unlock it first with the password you hold, since an encrypted document cannot be opened for editing. Sign the unlocked copy and protect it again afterwards if you need to. Unlock PDF
Can several people sign the same document?
Yes, by passing the file along: each person signs the version they receive and saves it, so the signatures accumulate. There is no signing workflow or email routing built in here.
