Sign PDF

Why sign PDFs with Tools Root

Printing a document just to sign it and scan it back in is one of the more tedious parts of paperwork, especially for a single signature on an otherwise-digital document. This free PDF signature tool skips that entirely, letting you sign directly in the browser tab you already have the document open in.

Three ways to create a signature that looks like yours

Drawing lets you sign with your actual hand motion using a mouse or touchscreen; typing renders your name in a script font for a quick, clean result; and uploading a photo of your real pen-and-paper signature gives the most authentic look if you already have one on hand. All three feed into the same drag-and-resize placement step, so the method you choose doesn't change how the signature gets positioned on the page.

A free alternative to paid e-signature software

Many e-signature platforms charge a monthly fee once you go beyond a handful of free documents, and require creating an account before you can sign anything. This tool applies a visual signature to a PDF with no signup, no per-document limit, and no recurring cost, processing everything locally rather than routing your document through a signing service's servers.

Common use cases

Signing a rental agreement or freelance contract without printing it, adding a signature to a form before emailing it back, countersigning a document that's already been signed by someone else, applying a consistent signature across several similar documents, or signing a waiver or permission slip sent as a PDF attachment.

Signing forms with real interactive fields

If the PDF you're signing has actual fillable form fields rather than a fixed layout, Fill PDF Forms is the better starting point for the surrounding fields, with this Sign PDF tool handling the signature itself either before or after the form is filled in.

What kind of signature this tool adds to a PDF

The signature placed on the document is a visual mark, drawn, typed, or uploaded as an image, positioned exactly where you click on the page, which is the same kind of signature most everyday agreements, forms, and approvals actually need. This is different from a cryptographic digital signature, which uses a certificate to verify identity and detect any subsequent tampering with the document at a technical level. For contracts or filings that specifically require that certificate-based verification, a dedicated digital-signature service built around that standard is the more appropriate tool.

Signing a document that will be printed after signing

A signature added digitally through this tool is embedded directly into the PDF's page content, so it prints exactly as placed, at the same size and position, when the signed document is later printed on paper. This makes it a reasonable stand-in for a physical pen signature on documents that ultimately need a printed, signed paper copy rather than only a digital one.
