Free online PDF signature tool
Need to sign a PDF online without paying for an account? This free electronic signature tool lets you add a signature to any PDF in seconds, directly in your web browser. There is nothing to install and nothing to sign up for. Whether you are signing a lease, an offer letter, an invoice, a consent form, an NDA, or a tax document, you can draw your signature, type it, or upload a signature image and place it exactly where it belongs. When you are done you download a clean, signed PDF with no watermark added.
Most “sign PDF online free” tools quietly upload your document to a remote server, stamp a watermark on the result, or push you toward a paid plan after a couple of uses. This tool is different. Everything happens locally using your browser, so the file you drop in never leaves your device. That makes it a safer way to e-sign confidential paperwork, and it also means signing is fast even on a slow connection because there is no upload or download round trip.
Draw, type, or upload your signature
You can create your electronic signature three ways. Draw it freehand with a mouse, trackpad, or your finger on a touchscreen for the most natural look. Type your name and let the tool render it as a signature when you just need a quick e-signature. Or upload a transparent PNG of your real signature if you already have one saved. Once your signature is ready, drag it anywhere on the page, resize it with the corner handle, flip between pages, and add it to the exact spot the document calls for. This is the same fill-and-sign workflow people expect from desktop PDF software, but free and in the browser.
A free alternative to DocuSign, Smallpdf, and iLovePDF
If you only need to add a signature to a PDF, a full e-signature subscription is often overkill. This page works as a free DocuSign alternative for simple self-signing, and as a no-watermark alternative to the Smallpdf and iLovePDF sign-PDF tools for quick jobs. It will not send signature requests to other parties or provide a legal audit trail the way a paid platform does, so for multi-party agreements that need certificates those services still have their place. For signing a document yourself and sending it back, this free tool gets it done without the cost or the account. FixItWhy is not affiliated with DocuSign, Smallpdf, or iLovePDF; those names are used only to describe comparable tools.
