Why Most “Free” PDF Signers Add Watermarks

Many online PDF tools advertise as “free” then stamp a visible watermark — “Signed with FreePDFTool.com” — across your finished document. You cannot send a contract to a client with a third-party watermark on it. The tool is effectively unusable for professional purposes unless you pay to remove it.

SigPDF takes a different approach. There is one flat subscription — from €2.08/month — and at every plan level your signed PDFs are completely clean. No watermarks on any page, no footer branding, no hidden marks. Your document looks exactly the way it should.

Frequently Asked Questions

Does SigPDF add watermarks to signed PDFs?
Never. SigPDF does not add watermarks, branding, logos, or any other markings to your documents at any subscription level. Your signed PDF looks exactly as you designed it.
Why do free PDF tools add watermarks?
Free tools typically use watermarks as a way to advertise their service and push users toward paid plans. SigPDF's model is different — you pay a flat subscription and get clean output with no watermarks, ever.
How much does SigPDF cost?
SigPDF costs from €2.08/month billed annually. You can preview the result for free before subscribing — open a PDF, place your signature, and see exactly how it looks before paying anything.
Can I try SigPDF before subscribing?
Yes. You can open any PDF, place your signature, and preview the full result without a subscription. A subscription is only required to download the signed PDF.
Is my PDF uploaded to a server?
No. SigPDF processes everything locally in your browser. Your files never leave your device — no upload, no cloud storage, no third-party access.
Is the signed PDF legally valid?
Yes. Electronic signatures created with SigPDF are legally recognized under the US ESIGN Act, EU eIDAS Regulation, and equivalent legislation in most countries. Watermarks have no bearing on legal validity — a clean PDF signed with SigPDF is fully enforceable.

Yes. SigPDF works in any mobile browser on iPhone, Android, and iPad. The output is always watermark-free regardless of which device you use to sign.
