How to fill and sign a PDF online
You can fill and sign a PDF entirely in your browser, no printing, no scanning, no account. Type into the form fields, tick checkboxes, drop in today’s date, then add your signature by drawing, typing or uploading it, and download the finished PDF. If the PDF has real form fields, PDF Verified detects them automatically so you can fill them like a web form; if it does not, you can add text and a signature anywhere on the page. Every signed PDF also gets a public QR verification page and a tamper-evident seal, so the person who receives it can confirm it is genuine and unchanged.
How to fill and sign a PDF online — step by step
- Upload your PDF — Open Quick Sign and drop your PDF in. It stays in your browser, nothing is uploaded until you choose to save. If the file has fillable form fields, they are detected automatically.
- Fill in the fields — Type into text boxes, tick checkboxes, choose from dropdowns, and insert the date. On a flat PDF with no form fields, drag a Text field wherever you need to type, and add the date and your name the same way.
- Add your signature — Drop a Signature field where you sign, then draw it with your finger or mouse, type it in a signature font, or upload a photo of your handwritten signature. Add initials or a company stamp if the document needs them.
- Download or send — Download the filled, signed PDF, or send it to someone else for their signature. Every completed document is sealed with a SHA-256 fingerprint and carries a public QR verification link on each page.

Frequently asked questions
How do I fill and sign a PDF for free?
Upload your PDF to Quick Sign, fill in the fields, add your signature by drawing, typing or uploading it, and download. There is no signup to start; you pay $1.50 only when you download a finished document, or it is free and unlimited on a paid plan.
Can I fill out a PDF that has form fields?
Yes. PDF Verified detects existing AcroForm fields automatically, so you can type into text boxes, tick checkboxes and pick from dropdowns just like a web form, then flatten them into the final PDF.
What if my PDF has no fillable fields?
Then it is a flat PDF. Just drag a Text field wherever you need to type, add the date and your name, and drop a Signature field where you sign, no form fields required.
Do I need an account to fill and sign a PDF?
No. You can complete the whole flow without an account. An account only becomes useful if you want to keep your documents, reuse a saved signature, or send files to others for signature.
Is a filled and signed PDF legally binding?
Yes. Electronic signatures are recognised under the US ESIGN Act and UETA, the EU eIDAS Regulation, and equivalent laws in 190+ countries. PDF Verified adds a tamper-evident seal and an audit certificate so the signed document holds up as evidence.
Can the recipient check the document is genuine?
Yes. Every signed PDF carries a public QR code and verification link. Anyone can scan it, with no account, to confirm who signed, when, and that the file has not been altered.
