Why FileReadyNow
The Simplest Way to Add a Signature to a PDF
No printing, no scanning, no software. Draw, type, or upload your signature and place it exactly where you need it.
Three Ways to Sign
Draw with your mouse or finger, type your name in a handwritten font, or upload a photo of your existing ink signature — whichever feels most natural.
Full Placement Control
Choose from nine positions on the page — top, middle, or bottom combined with left, center, or right. Apply to the last page, every page, or a specific one.
Private by Design
Your PDF and signature never leave your device. Everything — rendering the pages, placing the signature, and producing the signed file — happens locally in your browser.
Seconds, Not Minutes
Upload the PDF, create your signature, pick a position, and download. The whole process takes under a minute — no waiting for email links or account verification.
Works on Any Device
The signature pad works with a mouse on desktop and a fingertip on a phone or tablet — no stylus required. The tool adapts to any screen size automatically.
No Account Needed
No registration, no subscription, no watermarks added to your document. Sign PDFs freely, as many times as you like, for personal or professional use.
Step by Step
How to Sign a PDF Online for Free
Click the upload area or drag your PDF into the tool.
Draw, type, or upload your signature using the panel that appears.
Choose the position, page, and size for your signature.
Click 'Sign PDF' and your signed document downloads automatically.
Signing a PDF used to mean printing it, physically signing it, and then scanning it back in. That four-step process is now a single step. Upload your PDF, add your signature directly in the browser, and download the signed version. The file keeps its original formatting, fonts, and layout — only the signature is added.
What types of signatures you can create
- Drawn: use your mouse, trackpad, or finger on a touchscreen to write your signature freehand, exactly as you would on paper.
- Typed: type your name and choose a handwritten font — three styles are available — with full control over colour.
- Uploaded: if you already have a PNG or JPG scan of your ink signature, upload it directly. A PNG with a transparent background produces the cleanest result.
Placement and size options
The nine-position grid lets you place the signature in any corner, along any edge, or in the centre of the page. The size options — small, medium, large — control how much of the page width the signature occupies. You can apply the signature to just the last page (the most common case for contracts), to every page, or to a single page you specify by number.
When you need to sign a PDF
- Contracts and agreements: most service contracts, rental agreements, and freelance contracts are sent as PDFs. Sign them without printing a single page and email them straight back.
- HR and onboarding forms: offer letters, NDAs, policy acknowledgements, and benefits forms arrive as PDFs and need a signature before you send them to HR.
- Academic and government documents: university application forms, scholarship agreements, and many government submissions require a handwritten-style signature on a PDF.
- Invoices: adding a signature to an invoice adds a professional touch and satisfies clients or accounting departments that require an authorised signature.
- Personal documents: permission slips, tenancy agreements, consent forms — anything you would normally sign by hand but have received as a PDF.
Tips for the best-looking result
If you are drawing your signature, sign slowly and use a larger surface for precision — a tablet or large trackpad gives better control than a small phone screen. If you are uploading a scanned signature, scan it on a white background first, then use any image editor to remove the background and save as PNG before uploading. The transparent background means your signature will sit cleanly on the page without a white rectangle around it.
Privacy and file handling
Your PDF is never uploaded. The entire signing process — reading the file, rendering each page, placing your signature, and producing the final PDF — runs locally in your browser using client-side PDF libraries. Nothing is transmitted to, or stored on, our servers.
