Frequently Asked Questions

How do I insert a signature into a PDF?
Upload your PDF, create your signature by drawing it, typing your name in a handwriting font, or uploading an image of it, then drag the signature to the exact spot on the page and click Apply. Your signed PDF downloads instantly.
Is a signature added with this tool legally valid?
In most countries an electronic signature is legally recognised for everyday agreements under laws such as the U.S. ESIGN Act and the EU eIDAS regulation. This tool creates a visible electronic signature, which is what the vast majority of contracts, forms and consent documents require. It does not apply a certificate-based cryptographic digital signature, so if a document specifically demands a qualified or certificate-based signature, use a certificate authority service instead.
Can I sign a PDF without printing and scanning it?
Yes. That is exactly what this tool is for. You never need a printer or a scanner. Draw your signature directly in the browser with a mouse, trackpad or finger, position it on the page, and download the finished PDF.
Can I place my signature on more than one page?
Yes. You can add as many signatures as you like across different pages. There is also an "Place on all pages" button that stamps the same signature at the same position on every page, which is useful for initialling multi-page contracts.
Will the white background of my uploaded signature image show up?
No. When you upload a photo or scan of a signature the tool automatically removes the white and near-white background so only the ink remains. You can switch this off if your signature is on coloured paper.
Does signing change the rest of my document?
No. The signature is drawn as a new layer on top of the existing page content. All original text, images, fonts and formatting stay exactly as they were, and pages you do not sign are left untouched.
Is this PDF signature tool free?
Yes, it is 100% free with no usage limits, no account requirement and absolutely no watermark added to your signed PDF.
Can I sign a PDF on my iPhone or Android phone?
Yes. The tool runs entirely in your mobile browser and the drawing pad supports touch, so you can sign with your fingertip or a stylus. No app installation is needed.
Are my documents kept private?
Your file is transferred over an encrypted HTTPS connection, processed on a private server and then permanently deleted, along with the signed output, within 10 minutes. Nothing is shared or reused.
Can I sign a scanned PDF?
Yes. Scanned PDFs work the same way as digitally created ones because the signature is placed as an image layer over the page rather than inserted into editable text.

Three Ways to Create Your Signature

Everyone signs differently, so ToolTiny gives you three options in one place. Draw your signature freehand with a mouse, trackpad, finger or stylus for the most authentic look. Type your name and pick from four handwriting fonts if you want something clean and legible in a hurry. Or upload a photo of the signature you already sign on paper — the white background is stripped away automatically so only the ink lands on your document.

Place It Exactly Where It Belongs

A signature in the wrong place looks careless. Once your signature is ready, it appears directly on the rendered page where you can drag it onto the signing line and resize it with the corner handle until it fits. Move between pages with the thumbnail rail, add a signature to as many pages as you need, or stamp the same one across every page at once for multi-page contracts.

Your Original Document Stays Intact

The signature is composited onto the page as a new layer, so the text, images, fonts and formatting underneath are never re-rendered or recompressed. There is no watermark, no quality loss and no added page. Pages you did not sign come back byte-for-byte the same as they went in.

Privacy-Focused Document Signing

Signed documents are usually the sensitive ones. Every file you upload travels over an encrypted SSL channel, is processed on a private server, and is permanently deleted along with the signed output within 10 minutes. No account, no email address and no personal information are ever requested.

When You Need to Sign a PDF

Almost every document that used to require a pen now arrives as a PDF. Instead of printing a page, signing it, scanning it back and hoping the quality holds up, you can add a signature to a PDF online in under a minute and send it straight back.

Document Type Typical Use
Employment Contracts Offer letters, NDAs, onboarding paperwork
Rental Agreements Leases, tenancy renewals, deposit forms
Invoices & Quotes Approval sign-off before payment
School & Medical Forms Consent slips, permission letters
Government Applications Declarations and submission cover sheets

Electronic Signature vs Digital Signature

These two terms get used interchangeably, but they mean different things — and knowing the difference tells you whether this tool is right for your document.

Electronic Signature Digital Signature
What it is A visible mark showing intent to sign A cryptographic seal backed by a certificate
Verifies identity Through context and consent Through a certificate authority
Accepted for Most everyday contracts and forms Regulated filings requiring qualified signatures
This tool ✔ Yes ✘ No

ToolTiny produces an electronic signature, which under frameworks like the U.S. ESIGN Act and the EU eIDAS regulation is legally recognised for the overwhelming majority of agreements. If a specific authority or filing explicitly requires a qualified, certificate-based digital signature, you will need a certificate issued by a trust service provider instead. This page is general information, not legal advice.

Sign PDF Files on Any Device

Our online PDF signature tool works directly inside your browser and supports Windows, Mac, Linux, Chromebook, Android, and iPhone devices. No Adobe Acrobat installation, software download, browser extension, or account registration is required. On touch devices the drawing pad accepts your fingertip or a stylus, which usually produces a far better signature than a mouse.

Platform Support
Windows PC ✔ Supported
Mac ✔ Supported
Linux ✔ Supported
