Sign PDF Online with PdfMeta

PdfMeta's Sign PDF tool lets you add a legally valid electronic signature to any PDF directly in your browser. Draw your signature with a mouse or touchscreen, type your name and choose a style, or upload an existing signature image. Place it anywhere on any page, resize it, and download the signed document in seconds. The signature is embedded into the PDF — it's not a separate layer that can be accidentally removed.

Electronic signatures are legally binding for most commercial agreements under the US ESIGN Act, UETA, and EU eIDAS regulation. Whether you're signing a lease, approving a purchase order, or returning a signed NDA — PdfMeta handles it without printing, scanning, or mailing anything. Need to add notes alongside your signature? Need to flatten the signed document so fields can't be modified? Those tools work right after signing.

Sign PDF Online for Free

PdfMeta's signing tool is completely free. No subscription, no credit card, no daily limits, no watermarks on the output. Sign as many documents as you need, as often as you need, without hitting a paywall or being asked to upgrade. Most e-signature tools charge $10-30/month per user — PdfMeta doesn't charge anything.

All signing runs in your browser using client-side PDF processing. Your files and signature data are never uploaded to any server. Not the document content, not the signature image, not any metadata. When you close the tab, everything is gone from memory. This makes PdfMeta the right choice for signing contracts, employment agreements, medical consent forms, or any documents where uploading to a third-party server is not acceptable.

The tool works with all standard PDF versions and accepts files of any size. You can sign scanned PDFs, digitally generated PDFs, and even documents that have been previously merged or compressed. If you need to convert a Word document to PDF before signing, use Word to PDF first.

How to Sign PDF on PdfMeta

  1. Upload your PDF. Drag and drop the file into the upload area, or click to browse and select it from your device.
  2. Create your signature. Draw it with your mouse, trackpad, or finger on a touchscreen. Or type your name and select from multiple handwriting styles. Or upload a PNG/JPG of your existing signature.
  3. Place and resize. Click anywhere on any page to position your signature. Drag the corners to resize. You can add multiple signatures or initials on different pages.
  4. Download. Save the signed PDF to your device. From here you can flatten the document to lock all annotations, add password protection, or compress it before emailing.

How to Sign PDF on Mobile, iOS, Mac, and PC

PdfMeta's signing tool runs in the browser, so it works the same way on every platform — no app downloads, no plugins, no desktop software required.

  • Mac (Safari or Chrome): Upload from Finder. Draw your signature with a trackpad or mouse. The signed file downloads to your Downloads folder and opens in Preview. No Adobe Acrobat or DocuSign subscription needed.
  • Windows (Chrome, Edge, or Firefox): Upload from File Explorer. Draw with a mouse or use the type option. Output opens in Edge's built-in reader, Adobe Reader, or any PDF viewer.
  • iPhone and iPad (Safari, iOS 14+): Tap upload and select from the Files app. Draw your signature directly on the touchscreen with your finger or Apple Pencil — the most natural signing experience. Share the signed file via Mail, Messages, or AirDrop.
  • Android (Chrome): Tap upload and choose from device storage. Draw on the touchscreen with your finger. Works in Samsung Internet and other Chromium-based browsers.
  • Chromebook and Linux: Fully supported in Chrome, Firefox, or any Chromium-based browser. Draw with a trackpad or mouse, or use the type/upload option.

Who Uses PdfMeta's Sign PDF Tool

Printing a document, signing it by hand, scanning it back to PDF, and emailing it is a workflow that should have died years ago. It wastes time, requires a printer and scanner, and produces lower-quality output. PdfMeta replaces that entire process with three clicks in a browser.

What You Can Do with PdfMeta's Sign Tool

  • Draw signature: Use your mouse, trackpad, or touchscreen to create a natural handwritten signature. Adjust stroke thickness and color.
  • Type signature: Type your name and choose from multiple handwriting-style fonts for a clean, consistent look across documents.
  • Upload signature image: Use an existing PNG or JPG of your signature — useful if you've already digitized your handwriting.
  • Multi-page signing: Place signatures or initials on multiple pages within the same document — common for contracts that require initialing every page.
  • Precise placement: Click to position, drag to resize. The signature goes exactly where you need it, on any page of the document.
  • No watermark: Output is completely clean — no branding, no "signed with" text, no stamps on any page.
  • Chainable: The signed PDF works with every other PdfMeta tool. Flatten it, compress it, merge it with other documents, password-protect it, or add annotations — all immediately after download.

Privacy & Security

All signing runs in your browser using client-side processing. Your files and signature data are never uploaded to any server — PdfMeta has zero access to your documents or your signature. Not the content, not the image, not any metadata. When you close the tab, everything is gone from memory.

No account is required. No email. No personal information collected. This is the right approach for signing contracts, employment agreements, medical consent forms, financial documents, or anything where uploading to a third-party server is not acceptable. For additional protection after signing, use Protect PDF to add AES-256 password encryption before sharing.

Sign PDF FAQ

{[ ['Is an electronic signature legally valid?', 'Yes. Electronic signatures are legally binding for most commercial agreements under the US ESIGN Act, UETA, and EU eIDAS regulation. Exceptions include certain court orders, wills, and specific government filings that require wet ink or qualified digital signatures.'], ['Can I sign multiple pages?', 'Yes. You can place a signature or initials on any page of the document. This is common for contracts that require initialing each page and a full signature on the last page.'], ['What signature methods are available?', 'Three options: draw with your mouse, trackpad, or touchscreen; type your name and choose a handwriting-style font; or upload a PNG/JPG image of your existing signature.'], ['Does signing change the document quality?', 'No. The tool embeds your signature as an annotation layer. The original document content — text, images, fonts — remains untouched.'], ['Can someone remove my signature after I send the file?', 'Signatures added as annotations can technically be removed by someone with PDF editing software. To prevent this, use PdfMeta\'s Flatten PDF tool after signing — this permanently merges the signature into the page content.'], ['Is it really free?', 'Yes. No subscription, no per-signature fees, no credit card, no account required. Unlimited signatures, no watermarks.'], ['How does this compare to DocuSign or Adobe Sign?', 'PdfMeta handles the same core function — placing a signature on a PDF — for free. DocuSign and Adobe Sign add workflow features like multi-party routing and audit trails, which start at $10-30/month per user. If you just need to sign and send, PdfMeta does it at no cost.'], ].map(([q, a]) => (
