How to Sign a PDF Without Printing It: Free Methods for Every Device
For years, signing a PDF meant printing it out, scribbling on it with a pen, scanning it back in, and emailing the result. That workflow was slow, wasteful, and produced terrible-looking documents. It is also completely unnecessary in 2025.
Every major operating system and browser now supports electronic signatures. Whether you are finalising a rental agreement, returning an employment contract, or approving a school permission slip, you can sign the document digitally in under a minute — without a printer, scanner, or any installed software. Here is how to do it on every device.
The Quickest Way: Sign in Your Browser
If you want to sign a PDF right now without installing anything, the fastest route is PDFico's free Sign PDF tool. It works in any modern browser on any device, and your file never leaves your computer — everything runs locally.
- Open the tool. Go to PDFico Sign PDF and drag your PDF onto the page, or click to browse for it.
- Create your signature. Draw your signature with your mouse, trackpad, or finger. Alternatively, type your name and choose a cursive font style.
- Place and resize. Click where you want the signature to appear on the document. Drag the corners to adjust the size and position.
- Download. Click "Apply Signature" and download your signed PDF. The original file stays untouched on your device.
Because PDFico processes everything in your browser, there is no upload, no account required, and no watermark on the finished document.

Yes. In most countries, electronic signatures carry the same legal weight as handwritten ones for the vast majority of documents.
- United States: The ESIGN Act (Electronic Signatures in Global and National Commerce Act, 2000) gives electronic signatures the same legal standing as ink signatures for interstate and foreign commerce.
- European Union: The eIDAS Regulation (Electronic Identification, Authentication and Trust Services) recognises electronic signatures across all EU member states. A simple electronic signature is legally admissible; advanced and qualified electronic signatures offer additional evidential weight.
- United Kingdom: The Electronic Communications Act 2000 and subsequent case law confirm that electronic signatures are valid and enforceable in England, Wales, Scotland, and Northern Ireland.
Documents that commonly accept e-signatures: employment contracts, rental and tenancy agreements, NDAs, purchase orders, invoices, consent forms, insurance applications, and most business-to-business agreements.
Documents that may still require wet signatures: wills and testaments, certain notarised documents, powers of attorney (varies by jurisdiction), some court filings, and real estate deeds in certain states or countries. Always check your local requirements if you are unsure.
How to Sign a PDF on Different Devices
Mac — Using Preview
macOS has a signature tool built directly into Preview, the default PDF viewer:
- Open your PDF in Preview.
- Click the Markup toolbar button (the pen-tip icon), then click the Signature button.
- If you have not created a signature before, choose Trackpad (draw with your finger on the trackpad), Camera (hold a signed piece of paper up to your webcam), or iPhone (draw on your phone screen).
- Click your saved signature to place it on the document, then drag it to the correct position and resize as needed.
- Save the file. Preview stores your signature for future use.
Windows — Using Microsoft Edge or a Browser Tool
Windows does not include a built-in PDF signing tool in the same way macOS does, but you have two solid options:
- Microsoft Edge: Open your PDF in Edge. Click "Add signature" in the toolbar. Draw or type your signature, place it on the page, and save.
- Browser-based tool: Open PDFico's Sign tool in Chrome, Edge, or Firefox. This works identically to the method described above and requires no installation.
iPhone and iPad — Using Markup
iOS and iPadOS have a powerful Markup feature that works across multiple apps:
- Open the PDF in Files, Mail, or Messages.
- Tap the Markup icon (pen-tip) in the top-right corner.
- Tap the + button, then select "Signature."
- Draw your signature with your finger or Apple Pencil. Tap Done.
- Drag the signature to the correct position on the page and resize it. Tap Done to save.
Your signature is saved across all Apple devices signed into the same iCloud account.
Android — Using Google Drive or a Browser Tool
Android does not have a universal built-in signing feature, but there are reliable options:
- Google Drive: Open a PDF in Google Drive, tap "Fill out form" or use the annotation tools to add your signature. Availability varies by device and Android version.
- Browser-based tool: Open PDFico's Sign tool in Chrome or any mobile browser. The tool is fully responsive and works well on touchscreens — draw your signature with your finger directly on the screen.
Drawing vs Typing Your Signature
Most signing tools give you two options: draw a freehand signature or type your name in a cursive-style font. Each has its advantages.
When drawing works best: A drawn signature looks more natural and personal. It is the better choice for formal contracts, legal documents, and anything where you want the signature to closely resemble your handwritten one. If you are using a touchscreen device or an Apple Pencil, drawing produces excellent results.
When typing works best: A typed signature in a clean cursive font looks consistent and professional every time. It is ideal for high-volume signing — approving purchase orders, signing off on internal documents, or any situation where speed matters more than a personal touch.
Tips for drawing on a trackpad: Use slow, deliberate strokes rather than trying to replicate your natural writing speed. Start from the left edge of the trackpad and use the full width. Most tools let you retry as many times as you like, so do not settle for your first attempt. On a laptop trackpad, drawing with the side of your index finger often gives smoother lines than using the fingertip.
Keeping Signed Documents Secure
Once you have signed a document, there are a few extra steps worth taking before you send it on:
- Password protect after signing. If the document contains sensitive information, add a password so that only the intended recipient can open it. Use PDFico's Protect tool to encrypt the file directly in your browser.
- Compress before emailing. Signed PDFs with image-based signatures can be larger than the original. Use PDFico's Compress tool to reduce the file size before attaching it to an email.
- Keep unsigned originals as backups. Always save a copy of the original unsigned document. If you need to make corrections or re-sign with updated details, you will have the clean version ready without needing to request it again.
Common Situations That Require PDF Signatures
If you have never signed a PDF electronically before, you will likely need to soon. These are the most common scenarios where people are asked to sign and return a PDF:
- Rental and tenancy agreements — Landlords and letting agents routinely send lease agreements as PDFs for remote signing.
- Employment contracts and offer letters — Most HR departments now handle onboarding paperwork digitally.
- Non-disclosure agreements (NDAs) — Standard practice before any business discussion involving proprietary information.
- School and childcare forms — Permission slips, medical consent forms, and enrolment documents.
- Tax documents — Accountants and tax advisers frequently require signed authorisation forms.
- Insurance claims and applications — Insurers accept electronically signed claim forms and policy documents.
- Freelance and contractor agreements — Statements of work, service agreements, and invoices that require sign-off.
Sign, protect, and send — all from your browser with PDFico. No accounts, no uploads, no watermarks. Your documents stay on your device from start to finish.
