Sign a PDF online in minutes

Open the PDF you were sent, draw or type your signature, place it on the line and download the signed copy.

Drop your PDF hereSign up free and it opens in PDFs, ready to edit.

How to sign a PDF in four steps.

No printer and no scanner. Sign up free and it all happens in the editor.

  1. Step 1

    Open your PDF

    Drop it in the box at the top of the page. Once you’re signed in, it opens in the editor.

  2. Step 2

    Make your signature

    In Fill & Sign, choose Sign, then draw it, type it or use a picture of it.

  3. Step 3

    Place it on the line

    Click where it goes and resize it to fit. Add the date and your initials the same way.

  4. Step 4

    Download the signed copy

    Flatten your marks into the page as you save, then send the PDF back.

Draw it, type it or use a picture.

Three ways to make your signature, and the same three for your initials.

Add signature

Draw your signature above the line.

Everything the form asks for, not just the signature.

Fill & Sign puts text, ticks, initials and dates on any page, including scans with no form fields.

The PDFs editor in Fill & Sign, with a typed signature placed on an agreement’s signature line

  • Text anywhere

    Type a name, an address or a reference on any line of the page.

  • Ticks and crosses

    Mark the boxes that apply, even ones that are only printed.

  • Initials and the date

    Initial each page where it asks, and add today’s date in one click.

What people sign here.

Mostly the paperwork that arrives by email and wants a signature by the end of the day.

  • Contracts and NDAsSign a client’s agreement and send it back the same hour, without printing and scanning.
  • Supplier and onboarding formsFill in the details, tick the options, sign and date it in one pass.
  • Approvals and sign-offsInitial each line of a statement of work or a design sign-off sheet where it asks.
  • Scans with no form fieldsType onto a scanned form and put your signature on the printed line.

Sign it yourself, or send it to be signed.

Your own signature is free. When other people need to sign, that’s Docsiv’s e-signature, on paid plans.

Free account

Sign it yourself

Add your signature, initials, ticks and dates, then download the signed PDF. It’s saved to your workspace Drive, private until you share it.

Paid plans

Send it for signature

Place fields for each signer and they sign from a link in their email. Everyone gets the signed PDF and a certificate of completion.

Common questions.

Something else on your mind? Ask us in the chat, bottom right of the page.

Is it really free to sign a PDF here?

Yes. Opening a PDF, creating your signature, adding initials, dates, ticks and text, and downloading the signed copy are included on the Free plan. Your download is the PDF you opened with your marks on it, nothing added.

Where is my PDF kept?

Signing needs a free account, and when you save, the PDF goes to your Docsiv workspace Drive. Only people in your workspace can open it until you share a link.

How do I make my signature?

Open Fill & Sign and choose Sign. Draw it with a mouse, trackpad or finger, type your name and it’s set in a handwriting font, or use a picture of your signature (a PNG or JPEG up to 4 MB; transparency is kept). Initials work the same way.

Can someone move my signature after I send the PDF?

Turn on “Flatten Fill & Sign when saving” and your text, marks and signature become part of the page instead of objects that can be dragged about. That isn’t a lock: a PDF can always be edited by someone determined. When you need proof of who signed and when, send it for e-signature instead, which comes back with a certificate of completion.

Can I send a PDF to other people to sign?

Yes, on a paid Docsiv plan. You place signature, initials, date, name, text and checkbox fields for each signer, they sign from a link in their email, and everyone gets the signed PDF with a certificate of completion and its audit trail. The free plan covers signing a PDF yourself.

Is a drawn or typed signature legally binding?

Often, yes: many countries accept an electronic signature for everyday agreements. Rules vary by country and by document, though, and some need a witness, a notary or a qualified signature. This isn’t legal advice, so when it matters, ask the other party or a lawyer.

What’s the difference between an electronic and a digital signature?

An electronic signature is your mark on the page: drawn, typed or an image. A digital signature is certificate-based and shows whether the file changed after signing. Fill & Sign makes the first kind. If you have a digital ID file, the editor’s Certificates tools can apply the second.

Can I sign a PDF on my phone?

Yes, the editor runs in a mobile browser and you can draw your signature with a finger. Placing small marks precisely is easier on a larger screen.
