How to Sign a PDF Online Free — No App, No Signup (2026 Guide)

Printing a PDF just to sign it and scan it back — then emailing a 15 MB image file — is one of those workflows that should have died years ago. In 2026, you can sign any PDF directly in your browser in under 60 seconds, for free, without installing anything or creating an account. This guide shows you exactly how.

Whether you need to sign a rental agreement, a freelance contract, a school permission slip, or a business proposal, the process is the same. You have three signature methods available, and all of them produce a legally valid result in most countries.

What Is an Electronic Signature?

An electronic signature (e-signature) is any digital mark applied to a document to show intent to agree. It doesn't have to look like your handwritten signature — it can be a typed name, a drawn scrawl, or a scanned image of your ink signature. What matters legally is that it was applied with intent to sign.

This is different from a digital signature, which is a cryptographic certificate issued by a Certificate Authority (CA). Digital signatures are used in high-security government and financial workflows and require identity verification. For everyday documents — leases, NDAs, freelance contracts, school forms — a standard electronic signature is perfectly sufficient and legally binding in the EU (eIDAS regulation), the US (ESIGN Act and UETA), and most other jurisdictions worldwide.

Quick distinction: Electronic signature = your mark on a document (free, instant). Digital signature = cryptographic identity certificate (requires verification, often paid). Most people need the first kind.

3 Ways to Sign a PDF Online

PDFTash offers three signature input methods, each suited to different situations:

1. Draw Your Signature

Use your mouse, trackpad, or touchscreen finger to draw your actual signature directly in the browser. This produces the most authentic-looking result and works exactly like signing on a glass tablet at a bank or delivery service. On mobile, this method feels completely natural.

2. Type Your Name

Choose a handwriting-style font and type your name. PDFTash renders it in a cursive typeface that resembles a real signature. This is the fastest option when you're on a desktop without a touchscreen. The typed name is converted to an image and embedded into the PDF — it doesn't remain as editable text.

3. Upload a Signature Image

Sign on white paper with a black pen, take a photo or scan it, then upload the image (PNG with transparent background works best). PDFTash removes the white background automatically and places the signature cleanly over the PDF. This option is popular for people who want their exact handwritten signature reproduced precisely.

Step-by-Step: Sign a PDF with PDFTash

PDFTash doesn't add any watermark to signed PDFs on the free plan. The downloaded document looks professionally signed with no branding from us.

Yes — in most countries, an electronic signature carries the same legal weight as a handwritten signature for the vast majority of everyday documents. Here is the legal framework by region:

For maximum legal certainty — such as high-value contracts, mortgage documents, or legal proceedings — consult a lawyer about whether a qualified digital signature (with identity certificate) is required for your specific use case.

Frequently Asked Questions

Is an electronic signature made with PDFTash legally valid?

Yes, for most everyday documents. PDFTash e-signatures comply with ESIGN (USA), eIDAS (EU), and equivalent laws in most countries. The signed PDF includes metadata recording the timestamp of the signature event. For court filings, property deeds, or other high-assurance use cases, check whether your jurisdiction requires a qualified digital signature from a Certificate Authority.

How many PDFs can I sign for free?

PDFTash's free plan lets you sign PDFs up to 10 MB with no daily limit on the number of files. The free tier has no watermark. If you need to sign files larger than 10 MB or require advanced features like signature request workflows (sending a document to others for signing), the Pro plan covers those cases.

Does it work on mobile (phone and tablet)?

Yes. PDFTash is fully responsive and works in any modern mobile browser (Safari on iOS, Chrome on Android). The Draw signature option is especially natural on a touchscreen — just sign with your finger. No app installation is needed.

What is the difference between an electronic signature and a digital signature?

An electronic signature is any digital mark (drawn, typed, or uploaded image) that indicates intent to sign. A digital signature is a cryptographic certificate issued by a trusted Certificate Authority that mathematically binds your identity to the document. Digital signatures are used in regulated industries (banking, government procurement) and require identity verification. For everyday contracts and forms, an electronic signature is all you need.

Can I add my signature to a specific page of a multi-page PDF?

Yes. PDFTash's signing tool shows a page-by-page preview of your entire PDF. You can navigate to any page and place your signature exactly where needed. You can also add initials on some pages and a full signature on others — which is common for multi-page contracts.
