What “Free” Actually Means for PDF Signing Tools
When you search for a free online PDF signer, most results are tools that are free in name only. The typical catches: watermarks stamped on every page, hard limits of 2-3 documents per day, mandatory account creation before you can do anything, or aggressive paywalls that appear right before you download. Some tools also upload your documents to their servers even on the free plan, which creates real privacy risks.
SigPDF is transparent about its model: the signing tool itself is completely free to use. Upload any PDF, draw or type your signature, and place it exactly where you want it — with no account and no restrictions. Downloading the finished signed PDF requires a subscription starting at €2.08/month. No watermarks at any tier. No daily limits. No surprise paywalls in the middle of signing.
How to Sign a PDF Online in 3 Steps
- Open your PDF — drag it into the editor above or click to browse. Your file is opened locally in your browser and never sent to a server.
- Create your signature — draw it freehand with your mouse or finger, type your name and pick a handwriting font, or upload an existing signature image.
- Place and download — click anywhere on the page to place your signature. Resize and reposition as needed, then download. Your signature is permanently embedded in the PDF.

Why Browser-Based Signing is More Private
Every tool that uploads your document to a server creates a copy of your file on a third-party infrastructure. That company's employees could potentially access it, their servers could be breached, and their data retention policies determine how long it is kept. For routine documents this may not matter — but for contracts, NDAs, financial records, and medical forms, having your sensitive documents on a stranger's server is a real risk.
With SigPDF, this risk does not exist. Your document is opened by your browser, edited in memory, and downloaded as a new file — entirely on your own device. The entire process is architecturally offline from SigPDF's perspective.
