Practical guide
What is Sign PDF, and when should you use it?
Sign PDF opens your document in the BrieflyGo editor and lets you place a signature on it — drawn, typed, or from an image you already have — along with initials and a date where the page needs them.
It is best for signing a contract, returning a countersigned agreement, and initialling pages. Quick use does not require an account, although the current anonymous daily allowance may apply.
- Output
- The same PDF with your signature, initials and date placed on it, exported from the editor
- What it preserves
- Every page as it was — the signature is added on top, and the rest of the document is untouched
- Best for
- Contracts, engagement letters, offers, consent forms, and anything sent back countersigned
Common ways to use Sign PDF
Return a countersigned copy
Add your side of the signature to a document the other party already signed, so the file that goes back into both records is the fully executed one.
Initial specific pages
Some agreements ask for initials on every page or beside a particular clause. Place initials page by page instead of printing the whole document.
How to use Sign PDF
Open the PDF
Drop in the document you need to sign. It opens in the editor in the same tab.
Place your signature
Draw, type, or upload a signature image, then drag it onto the signature line and size it to fit. Add initials and the date if the page asks for them.
Export the signed PDF
Download the finished document. Export before closing the tab unless you are signed in, because anonymous work is not saved.
Limits and checks before you use the result
- This places a signature on the page. It does not by itself record who signed, from where, or when — if you need that evidence, send the document for signature instead, which captures a signer identity, timestamp and audit trail.
- Certain documents still require a wet signature or a witnessed or notarised process — many deeds, wills and some property and immigration filings among them. Check before signing electronically.
- A signature image can be copied by anyone who receives the file. Keep the exported PDF where you would keep other sensitive documents.
- Work in the editor is not stored unless you are signed in. Export the signed PDF before closing the tab.
Sign PDF FAQ
How do I sign a PDF without printing it?
Open the PDF here, choose how you want to sign — draw with a mouse, trackpad or finger, type your name in a signature style, or upload an image of your signature — position it on the signature line, and export. Nothing is printed or scanned.
Is an electronically signed PDF legally binding?
In many countries electronic signatures are recognised for most commercial agreements, and frameworks such as the US ESIGN Act and the EU eIDAS regulation set out when they hold. What makes one defensible in a dispute is the record around it: who signed, when, and against which version. A signature placed as an image carries none of that on its own, so use the send-for-signature flow when the document matters. This is general information, not legal advice — check with a qualified lawyer for your situation.
What is the difference between signing here and sending for signature?
Signing here puts your own signature on the page and gives you a PDF. Sending for signature invites someone else to sign, protects the link, records the signing event, and returns a signed document with an audit trail. Use the first for your own signature, the second when you need proof of theirs.
Can I use a signature I already have as an image?
Yes. Upload a PNG or JPG and place it on the page. A transparent PNG sits cleanly over the ruled signature line — the handwritten signature generator produces exactly that if you do not have one yet.
Can I add the date and my initials too?
Yes. Initials and a date stamp are separate elements you can place independently, which is what most agreements actually ask for beside the signature block.
Does signing change the rest of the document?
No. The pages are left as they are and the signature is drawn on top, so text stays selectable and nothing is re-rendered as an image.
Is my PDF uploaded anywhere?
No. The file is handed straight to the BrieflyGo editor in the same browser tab, so the document stays on your device while you work on it. The flip side is that nothing is saved for you either: if you are not signed in, closing the tab loses the work, so export the finished PDF before you leave.
Is it really free, and is there a catch?
It is free with no daily cap, no signup and no watermark added to your document. An account is optional and only buys persistence — saved files, history, and sending a document out for signature. Nothing here is time-limited or card-gated.
Do I need to install anything?
No. Everything happens through the browser on desktop or mobile — no extension, no desktop app, and no Acrobat licence. That also means it works the same on Windows, macOS, Linux, iOS and Android.
Understand the agreement before you sign it.
Review risky clauses in plain English, fix the document, and keep it moving toward signature.
