Signing should not be a project

Sign PDFs in Your Browser

A contract needs a signature and a return email — not an account, an invite chain, and a third-party signing platform. PDFTasker lets you draw, type, or upload a signature and place it directly on the page, all in the browser. The document — often full of names, terms, and ID details — never leaves your device to get signed.

Privacy and trust

No broken workflow

Signing is exactly the moment a document is most sensitive, so PDFTasker keeps the whole flow local: create the signature, position it on the page in a live preview, and export the signed PDF without a single upload. No bouncing between a tool and a signing service, and no copy of your contract sitting in someone else's storage.

FAQ

Sign PDF FAQ

Can I sign directly with a mouse or touch input?

Yes. You can draw a visible signature in the browser with a mouse, trackpad, stylus, or touch input. You can also use a typed mark or image signature when that fits the document. The important step is reviewing placement in the final PDF before sending it.

Can I place the same signature on multiple pages?

Yes. Apply the signature to one page, all pages, or a selected range when the document calls for repeated marks. Still check the final output manually. Multi-page signing is convenient, but long forms can have initials, full signatures, and date fields in different places before sending.

Do I need to sign up or log in?

No. PDFTasker does not require an account for the basic visible-signature workflow. The PDF loads in your browser, the signature mark is placed locally, and the signed copy downloads to your device. That avoids creating an account trail for a simple one-file signing job later.

Is this the same as a certificate-backed digital signature?

No. PDFTasker places a visible signature mark on the page. It is useful for many everyday forms, approvals, and packets, but it is not a certificate-backed digital signature with identity verification, cryptographic validation, or a platform audit trail. Follow the recipient's required process instead when asked.

Does signing upload my contract or form?

No. The signing workspace is browser-local. That matters because signed PDFs often contain names, addresses, payment terms, ID numbers, or client details. If all you need is a visible mark, the file should not have to leave your device first for processing or storage elsewhere.

Is a drawn signature legally valid?

In many places a visible electronic signature is accepted for routine agreements, but legal validity depends on your jurisdiction and the document. For anything regulated — notarized, audited, or formally witnessed — use the system built for that. PDFTasker is for the common case of signing and sending back.

Can I type my signature or upload an image instead of drawing?

Yes — three input modes cover the common cases. Draw the signature with a mouse, trackpad, or finger; type your name and let the tool render it in a signature style; or upload an image of your real ink signature. A transparent PNG gives the cleanest upload result, because the mark sits directly on the page instead of inside a white box. Whichever mode you choose, placement works the same way: the mark appears on the preview and you position and size it by hand.

Does the signature stay fixed when I send the file?

Yes. On export, the signature image is embedded into the page content of the PDF itself — it is not a floating annotation or a temporary layer that a viewer can toggle off or strip on save. Whoever opens the file sees the mark exactly where you placed it, in any standard viewer. The flip side is worth knowing too: once exported, the signature is part of the page, so keep your unsigned original in case a revised version needs signing later.
