Sign PDF

Quick answer: Sign PDF is a free online tool to sign a PDF without uploading that adds a visible text signature right in your browser. Type your name, choose a position, click Sign PDF, and download — nothing is ever uploaded to a server.

A visible signature is what most everyday documents need: a name written on the page, in a clear script-style font, exactly where a signature belongs. It is fast, it needs no printing or scanning, and the signed file looks ready to send.

What is Sign PDF?

Sign PDF without uploading means placing your name as visible signature text on a PDF page — all on your own computer or phone, with no file ever travelling to a server.

Please note the limit clearly: this is a visible signature only. It is not a certified or cryptographic digital signature, it carries no certificate, and it does not prove who signed in a legal or tamper-evident sense. For contracts that require a certified digital signature, use a dedicated signing service.

How to use Sign PDF

  1. Click the upload area and choose one PDF file.
  2. Type your signature text, for example your full name.
  3. Choose the position, font size, and whether to sign all pages, the first page only, or the last page only.
  4. Click the “Sign PDF” button. Your browser adds the signature locally.
  5. When processing finishes, the signed file downloads automatically as a new PDF.

Sign PDF use cases

Signing letters and approvals

Approval letters, cover letters, and internal memos often just need a visible signature. This tool adds one in seconds.

Signing the last page of a document

Choose “Last page only” to sign exactly where a signature block usually sits, without marking every page.

Preparing a document for email

A signed PDF can be emailed immediately, with no printing, signing by hand, and scanning back in.

Tips

  • Use your full name as it appears on the document, not a nickname, for formal letters.
  • Check the signed page before sending — position and size matter, especially on crowded pages.
  • If a document requires a certified signature, do not rely on a visible signature alone.
