Why Most PDF Tools Force You to Sign Up — And Why SigPDF Does Not

The majority of online PDF signing tools require you to create an account before you can even see the tool. The reason is straightforward: these platforms upload your documents to their cloud servers, and they need an account to associate your files with you, track your usage, and upsell you on storage and premium features.

SigPDF works differently. Your PDF is opened and processed entirely inside your web browser using client-side JavaScript. There are no files to store on a server because your document never leaves your device. That means there is no reason to collect your email address or create an account — the tool simply does not need it.

No Watermarks — Ever

Many “free” PDF signing tools produce signed documents with a watermark — a banner or logo added to every page saying something like “Signed with [Tool Name].” This makes the document look unprofessional and, in some cases, may not be acceptable to the recipient.

SigPDF never adds watermarks to your documents under any circumstances. Whether you are using the free preview or a paid subscription, your signed PDF contains only what you put there — nothing else.

Is Signing Without an Account Legally Valid?

Yes. The legal validity of an electronic signature has nothing to do with whether you created an account with the signing platform. What the law cares about is intent — that you intentionally placed a signature on the document to indicate your agreement. The US ESIGN Act, EU eIDAS Regulation, and equivalent laws in the UK, Canada, and Australia all recognize this. A signature created with SigPDF without an account is just as legally binding as one created with a full DocuSign enterprise subscription.

Frequently Asked Questions

Can I really sign a PDF without creating an account?
Yes. You can open any PDF in SigPDF, draw or type your signature, and place it on the document without registering or providing an email address. A subscription is required to download the finished PDF, but you can preview the full signing experience for free.
Will my signed PDF have a watermark?
No. SigPDF never adds watermarks, branding, or logos to your documents — on free previews or paid downloads. Your signed PDF looks exactly as you designed it.
Why do most PDF signing tools require signup?
Most tools require an account so they can store your documents on their servers and upsell you on storage, sharing, and workflow features. SigPDF processes everything in your browser, so there is nothing to store and no reason to collect your email address.
Is signing a PDF without an account legally valid?
Yes. The legal validity of an electronic signature does not depend on whether you created an account. What matters is intent to sign, which is established by the act of placing your signature on the document. This is recognized under the US ESIGN Act, EU eIDAS, and equivalent laws in most countries.
What is the difference between SigPDF and free tools like Smallpdf or iLovePDF?
Smallpdf and iLovePDF upload your documents to their cloud servers for processing. SigPDF processes everything in your browser — your files never leave your device. Smallpdf also limits you to 2 free tasks per day and requires an account for more. SigPDF has no daily limits and no account requirement to use the signing tool.
How much does it cost to download the signed PDF?
Downloads require a subscription starting at €2.08/month billed annually. There are no per-document fees, no envelope limits, and no watermarks. Cancel anytime.
Does SigPDF work on mobile without an app?
Yes. SigPDF works in any mobile browser — Safari on iPhone and iPad, Chrome on Android — without downloading an app. Sign PDFs with your finger directly in the browser.
