How to sign a PDF online for free
Sign any PDF in four quick steps — no Adobe Acrobat, no signup, no file upload. Everything runs locally in your browser so your documents stay private.
2
Create your signature
Draw your signature with a mouse or finger, or type your name and pick from eight handwriting fonts.
3
Place the signature
Click anywhere on the PDF to stamp the signature. Drag to reposition, drag a corner to resize, or click ✕ to remove.
4
Download the signed PDF
Click Download signed PDFs. One PDF downloads directly; multiple PDFs are bundled into a single ZIP.
5
Bulk sign multiple PDFs (optional)
With two or more PDFs open, click a placed signature to select it, then click Bulk Sign. The signature is applied to every open PDF at the same page and position — no need to place it manually on each file.
Why use a browser-based PdfSignOff?
Traditional PDF signing tools require you to upload your document to a remote server. That creates privacy and security risks — your contracts, tax forms, and personal documents travel across the internet and may be stored on third-party infrastructure. A browser-based PdfSignOff like this one uses client-side JavaScript to render and modify PDFs entirely on your device, so nothing is ever transmitted.
Draw vs. type your electronic signature
You can create your signature two ways. Draw mode lets you sign with a mouse, trackpad, or finger for a natural handwritten look. Type mode converts your name into a stylized signature using handwriting fonts such as Allura, Great Vibes, and Dancing Script. Both produce an image that is embedded directly into your PDF.
Signing multiple PDFs at once
Load several PDFs into separate tabs, sign each one, and click Download. All signed PDFs are bundled into a single ZIP file with a manifest that lists how many signatures were embedded in each document. This is ideal for signing batches of invoices, offer letters, or NDAs. For identical documents that need the same signature in the same place, use Bulk Sign to apply one signature across all open PDFs instantly.
Your privacy is the whole point
Most "free" PdfSignOffs upload your files to a server. This one doesn't. That's the entire design.
No file uploads, ever
Your PDF never leaves your device. Everything happens locally in your browser using JavaScript.
Nothing is stored
Close the tab and everything is discarded from memory. No cookies, no local storage, no server-side copies.
No tracking
No analytics, no pixels, no third-party scripts running on your documents.
Works offline
After the page loads once, you can disconnect from the internet and keep signing PDFs offline.
Frequently asked questions about signing PDFs
Is this PdfSignOff really free?
Yes. Signing PDFs here is completely free — no fees, no premium tier, no usage limits, and no watermarks on your signed documents.
Are my PDFs uploaded to a server?
No. All processing happens locally in your browser. Your PDFs never leave your device and are never transmitted to any server, CDN, or third party.
Do I need to sign up or create an account?
No account, email, or signup is required. Open the page, add your PDF, sign it, and download.
Can I sign multiple PDFs at once?
Yes. Load multiple PDFs into separate tabs, sign each one, then click Download signed PDFs. All signed PDFs are bundled into a single ZIP file. You can also use Bulk Sign to apply the same signature to the same location across all open PDFs.
How do I resize or move a signature?
Click a placed signature to select it. Drag the signature body to move it, or drag any of the four corner handles to resize it. Click the red ✕ button to remove it.
Does the tool work offline?
Yes. After the page has loaded once, you can disconnect from the internet and continue signing PDFs — all processing is local.
Is the signature legally binding?
This tool produces an electronic signature — a visual signature image embedded in the PDF. For many everyday documents this is sufficient. For contracts that require a certified digital signature with certificate-based identity verification, use a dedicated certified e-signature provider.
What PDF file types are supported?
Any standard PDF is supported. Encrypted or password-protected PDFs must be unlocked in a PDF reader before signing.
How is this different from Adobe Acrobat or DocuSign?
Adobe Acrobat and DocuSign are full-featured platforms with certified signatures, audit trails, and cloud storage — but they require accounts, subscriptions, or file uploads. This tool focuses on the single most common task: adding a visible signature to a PDF quickly and privately, for free, without uploading anything.
What does Bulk Sign do and when should I use it?
Bulk Sign applies one selected signature to every open PDF at the same page number and position. It's useful for batches of identical documents — invoices, offer letters, NDAs — where the signature belongs in the same spot on each file. A single signature only marks the one document you placed it on; Bulk Sign copies that placement to all other open PDFs at once. To use it: place a signature, click it to select it, then click Bulk Sign.
Can I sign XFA forms and will the form fields be preserved?
Partially. XFA (Adobe XML Forms Architecture) is a deprecated Adobe-proprietary format that most modern PDF viewers — and the open-source pdf-lib library used here — cannot fully round-trip. This tool tries three strategies in order: (1) direct edit, which preserves AcroForm fields and XFA for most PDFs; (2) drop XFA, which removes the XFA stream but keeps the visible AcroForm fields intact — this works for static XFA PDFs and is what saves most filled-in forms; (3) rebuild, a last resort that copies only page content and strips interactive form fields entirely, producing an openable PDF where the fields are no longer editable. The
MANIFEST.txt inside the ZIP reports which method was used for each file. If your XFA form is dynamic (produced by Adobe LiveCycle or AEM Forms Designer), no client-side library can preserve the fields — pre-convert the file to a standard AcroForm PDF using a converter such as the Aspose XFA→AcroForm web app before signing.
