Sign a PDF online
Drop in a PDF, put your signature where it belongs, and download the signed file. No software to install, no printing, no scanning, and no account needed to start.
How to sign a PDF online
- Open Quick Sign and drop your PDF onto the page.
- Click where you need to sign to place a signature field.
- Draw your signature with a mouse, finger or stylus, type it in a signature font, or upload a photo of your handwritten one.
- Add initials, a date, free text or a company stamp anywhere else they are needed.
- Download the signed PDF, or send it on for someone else to sign.
What you can put on the page
- Signature and initials. Draw, type or upload once, then reuse them on every field in the document.
- Date and text. Typed onto the page as text, not as a picture of text.
- Company stamp or seal. Design one in the stamp maker and apply it here.
- Letterhead or logo. A resizable image near the top of the page.
- Watermark and highlight. Mark a draft, or draw attention to a clause.
- Existing form fields. Fillable fields already in the PDF are detected on open and flattened on download.
Why sign here rather than paste a picture in
- It can be checked later. The finished PDF is sealed and its SHA-256 hash recorded, so anyone can verify whether a page changed after signing. A pasted image proves nothing about who applied it or when.
- The layout survives. Fields are drawn onto the page itself, so nothing reflows and no paragraph moves down to make room.
- The file does not leave your device to be signed. An anonymous document is opened, edited and sealed in your own browser.
Frequently asked questions
How do I sign a PDF online?
Open Quick Sign and drop your PDF onto the page. Click where you need to sign, then draw your signature with a mouse, finger or stylus, type it in a signature font, or upload a photo of your handwritten one. Add initials, a date, free text or a company stamp anywhere else you need them, then download the signed file.
Do I need an account to sign a PDF?
No. Uploading, placing fields and previewing the signed document all work without signing up, and you can pay for a single download as a guest. An account is only worth having if you want the signed copies kept in a dashboard, saved signatures offered on every document, or a plan that includes downloads.
Is it free?
Opening a PDF, placing every field and previewing the finished document is free. Downloading the signed PDF is $1.50 as a one-off, and it is included at no extra cost on any paid plan. You never pay before you can see exactly what you are getting.
Does the PDF stay on your servers?
The signing itself happens in your browser. The PDF is opened, the fields are drawn onto it and the file is sealed on your own device, so an anonymous document is never uploaded anywhere to be signed. Signed in with an account, a copy is saved to your dashboard afterwards so you can find it again.
Can I fill in a PDF form as well as sign it?
Yes. Quick Sign detects the fillable fields already in a PDF when you open it and offers them alongside the ones you place yourself. On download the form is flattened, so the values become part of the page instead of staying editable.
What can I add to the page?
A signature, initials, a date, free text, checkboxes, a company stamp or seal, a letterhead or logo, a highlight, and a watermark across the page. Anything you place can be dragged, resized and undone with Ctrl+Z or Cmd+Z.
What do I get back?
A signed PDF by default. The same document can also be downloaded as PNG or JPG images, zipped when it runs to more than one page.
Is a signature added this way legally binding?
ESIGN, UETA and eIDAS turn on intent to sign, consent, association with the record and retention, not on how the mark was drawn. Quick Sign seals the finished PDF and records its SHA-256 hash, so anyone can later check at /verify whether a page has been altered since it was signed. That is the part a pasted picture of a signature cannot do.
Can I sign on a phone?
Yes. The editor works on a phone or tablet, and a finger or stylus is a better signing instrument than a mouse. You can also sign from your phone and finish on a desktop.
What PDF Verified is, and what it is not
A stamp identifies who issued a document. It is evidence rather than a formality that makes a document binding on its own, and it should only ever be made and applied for a business or an office you are authorised to act for: a mark that imitates another organisation in order to pass a document off as theirs is forgery in most places. Where a registry, a bank or a counterparty requires a particular form of seal, that requirement comes from them.
PDF Verified is a tool for preparing, signing, stamping and checking documents. It is not a law firm, a compliance service or a forensic examiner, and nothing here is legal, financial or compliance advice. Requirements differ by country, by document type and by the party asking, so check what applies to your document before you rely on it, and take advice where the document matters. You are responsible for the documents you create, sign and send, and for having the authority to do so: signing or stamping in somebody else name, or as an organisation you do not represent, is forgery whatever tool is used. To the extent the law allows, we accept no liability for how a document made with this tool is used or relied on. The full position is in our terms of service.
