Sign a PDF online — free, no account, no uploads
Open your PDF right in the browser, click where the signature belongs, and add it — draw it with your mouse or finger, type it and pick a style, or upload a photo of your ink signature. Add dates, initials, checkboxes and text the same way, then download the finished file or share it straight from your phone. The whole thing takes about 90 seconds, and you never create an account.
When you sign your own document, FairSign runs entirely on your device: the PDF is processed locally in your browser and is never uploaded to any server. That matters when the file is a lease, an NDA or a client contract. Password-protected PDFs are unlocked locally too — the password never leaves your device. Files up to 50MB and 200 pages are supported, and if something can’t be processed we say so instead of failing silently.
Local & private — never uploaded. Free, no watermark.
Common questions
Is it really free?
Yes. Signing your own PDFs is free and unlimited — no account, no watermark, no trial that flips into a paid plan. We charge only when you send documents to other people for signature, and even that includes 3 free requests every month.
Is my PDF uploaded to your servers?
No — self-signing happens 100% in your browser, so the file never leaves your device. If you later send a document to someone else for signature, that does go through our servers: encrypted in transit and storage, auto-deleted 30 days after completion, and you can delete everything anytime.
Is a drawn or typed signature legally valid?
For most everyday business documents, yes: electronic signatures are recognized under laws like ESIGN (US) and eIDAS (EU). Documents sent through FairSign also get a completion certificate and a tamper-evident audit trail. Requirements vary by document type and jurisdiction, so check the rules that apply to you — this isn’t legal advice.
