You can sign a PDF, or send one to someone else to sign, right here in your browser. To request a signature, open the document, mark where each signature and date should go, and download a ready-to-send PDF you email yourself. The other person opens that same file here, the signature fields appear automatically, they draw or type their signature, and the finished PDF gets a tamper-evident certificate (a SHA-256 fingerprint of the exact signed document) plus the signer’s name and time. Nothing is uploaded — the document is signed on each person’s own device — with no account and no watermark.
How to sign a PDF or request a signature
Open your PDF — if it was already prepared for signing, the fields appear automatically.
To request a signature: mark where each signature/date goes and download a file to email to the signer.
To sign: draw or type your signature in each field, then download the signed PDF (with its certificate) and email it back.
Limits & good to know
Everything runs in the browser with no server, so the document is routed by your own email: you send the prepared file, and the signer emails the signed copy back. There is no automatic delivery or reminder tracking.
Signatures can be drawn or typed, placed on the fields you mark (signature, initials, date, or text).
The completed PDF gets a certificate page with a SHA-256 fingerprint of the exact signed document, the signer’s name, and the date — so any later change to the file is detectable.
The signer’s name and consent are recorded as stated by the signer; identity is not independently verified the way a paid, server-backed service with email/ID checks would.
A password-protected PDF must be unlocked before it can be prepared or signed.
Frequently asked questions
Are my files uploaded to a server?
No. TrulyFreePDF runs entirely in your browser — your file is opened and processed on your own device and is never uploaded, stored, or shared.
Is an electronic signature made this way legally valid?
In many places an electronic signature — a mark you apply intending to sign, with a record of what was signed and when — is valid for common agreements (US ESIGN/UETA, EU eIDAS “simple” electronic signatures). This tool records the signer’s name, the time, and a tamper-evident fingerprint of the exact document. It does not independently verify the signer’s identity (email or ID checks), which some higher-assurance uses require, so for high-stakes contracts check what your situation needs.
How does the other person sign if nothing is uploaded?
You email them the prepared PDF yourself. They open that same file here in their browser — the signature fields are stored inside the file, so they appear automatically — they sign on their own device, and email the signed copy back. The document is never uploaded to us at any step.
Can I tell if a signed document was altered afterward?
Yes. The certificate page carries a SHA-256 fingerprint of the exact document that was signed. Load your original alongside the signed copy and the tool compares the fingerprints — if they differ, the document changed. This all happens on your device.
Is this really free, or free "until you hit a limit"?
Really free. Unlike most "free" PDF sites there is no task-per-day cap, no locked Pro features, no watermark stamped on your file, and no payment step before download. Every tool is the full tool.
