Add a Signature to a PDF, Free
Adding a signature to a PDF should not require a subscription, a free trial that expires after three documents, or handing your file to a service that emails you to upgrade a week later. FixTools keeps it genuinely free. You open the tool, upload the PDF, draw your signature in a pad, position it on the page, and download the signed document with no watermark and no sign-up. There is no per-signature counter and no paywall waiting at the download button. It stays free because the work happens in your browser rather than on a server that costs money to run, which also means your document is never uploaded. For anyone who signs the occasional form and resents being funneled toward a paid plan, this is the tool that simply does the job and gets out of the way.

What "free" usually hides, and why this is different
Many free PDF signing sites are free only up to the download. You draw your signature, then the export button asks for an account, adds a watermark unless you pay, or limits you to a few documents a month. The task itself is trivial for a browser to do, so the limits exist to sell a subscription rather than to cover any real cost.
FixTools does the signing locally in your browser, so there is no server bill to recover and no reason to gate the download. You get the finished PDF with your signature and nothing else added. The trade you are making is simply that the tool is a web page rather than a heavyweight app, which for signing a form is exactly the right trade.

Pro tips
Get better results with these expert suggestions:
Bookmark the tool
Since there is no account, bookmark the page so it is one tap away the next time a form arrives.
Reuse your best signature
Draw a version you are happy with and screenshot it, so you can match the style next time.
Check the placement at full zoom
Zoom to 100 percent before downloading to be sure the signature sits exactly on the line.
Pair with the compressor
If the signed PDF needs to go through an upload form with a size cap, compress it first, also free.
