How to sign a PDF without Adobe — free, in a browser tab
To sign a PDF without Adobe, open Sign PDF in a browser, draw or type your signature, drag it onto the line and click Apply signature. Free, no account, nothing uploaded, and form fields stay fillable.
The surprise in signing a PDF without Adobe is that you never needed Adobe for it. A drawn signature is a picture placed on a page, and plenty of things already on your computer can put one there. This covers the browser route step by step, what it keeps intact in your document, and which other free route fits which situation.
Can you sign a PDF without an Adobe license?
Yes. A drawn or typed signature is an image stamped onto the page, and placing one needs no license from anyone. Adobe's own free Acrobat Reader includes Fill and Sign, and outside Adobe you can use Preview on a Mac, the Draw pen in Microsoft Edge, or Sign PDF in any browser tab.
How do I sign directly on a PDF?
Open Sign PDF, choose the file, draw your signature with a mouse, trackpad or finger (or type your name), click Use signature, drag it onto the line and click Apply signature. The signed copy downloads with _signed on the end of its name, and your original file is not changed.
Open the tool
Open Sign PDF in any browser. There is nothing to install and no account to make.
Choose the PDF
Click the upload area and pick the file. Every page is rendered on your computer first, so a long document takes a moment before the signature pad appears.
Draw or type your signature
Draw on the pad in black or blue ink, or switch to Type and enter your name to have it set in a script face.
Confirm it
Click Use signature. It is trimmed to its own edges, so the empty space around your name does not travel with it.
Place it and apply
Use the page arrows to reach the right page, drag the signature onto the line, resize it from a corner handle, then click Apply signature. The signed copy downloads.
Can I sign a PDF document for free?
Yes, with no trial and no account. Sign PDF is free because it costs almost nothing to run: the page loads once, then your file is read into the tab, the signature is stamped there and the signed copy is built there. Nothing is uploaded, because there is no server to upload it to.
That is the question worth asking of any free signing site, since the document you are signing is usually a lease, an offer letter or a form with your address on it. Here the signature lives only as an image held in the open tab. Loading another file clears it, closing the tab discards it, and no signature is saved for next time.
Does signing a PDF this way flatten the form?
No. The signature is written into the page's own content and everything else is left as it was. We signed a filled-in form and read the result back with a separate PDF library: the field was still a live, editable field holding its value, the text was still selectable, and the title and author had survived.
That matters when the document is going on to someone else who still has boxes to fill in. Signing does not lock them out, and it does not turn the page into a flat picture of itself.
Put the signature on the signature line, not inside a form box. A form field is drawn on top of the page, so a box with a filled background can cover a signature placed underneath it. If the form has typed fields as well, complete them first in Fill PDF Forms and then sign.
How do I electronically sign a PDF file?
It depends on which kind of electronic signature the other side wants. A drawn or typed mark, which is what Sign PDF, Preview and Fill and Sign produce, is enough for delivery notes, school forms and internal approvals. A certificate-based digital signature, which proves who signed and exposes later edits, needs a signing service; this tool does not make one.
If you are not sure which one a document calls for, Drawn, typed, digital: three kinds of PDF signature sorts them out. For a contract a court might one day read, use a proper e-signature service.
What is the best free way to sign a PDF?
The one already in front of you. Each free route below is the right answer somewhere, and the browser tab is the one that works on any computer, including ones that are not yours.
- On your own Mac, Preview has a Sign tool built in. How to sign a PDF on Mac covers it, and the two cases where it gets in the way.
- On Windows, Microsoft Edge opens PDFs with a Draw pen you can sign with freehand, which suits a touchscreen or a pen better than a mouse.
- On a phone, see signing on an iPhone or on Android.
- On a shared, library or work computer, or when you want a typed signature, use Sign PDF. It stores nothing, so nothing is left behind for the next person.
A typed name looks different depending on the computer that made it. The tool asks for Segoe Script first, so on Windows that is the face you get; a Mac falls through to Bradley Hand, and many other systems to a generic cursive. And each pass places one signature on one page, so initials on three pages means three rounds of sign, place and download.
