Sign PDF

Why Sign PDFs Online?

According to Fortune Business Insights, the global e-signature market reached $7 billion in 2024 and continues growing at 30%+ annually. Every day, millions of contracts, agreements, NDAs, tax forms, and legal documents require a signature before they can be processed. Printing, signing by hand, scanning, and emailing back is slow and wasteful — especially when all you need is a simple signature on a PDF.

PDFJolt lets you sign any PDF document in seconds. Draw your signature with your mouse or finger, type your name in a script font, or upload an image of your signature. Then drag it exactly where you need it on the page. The entire process happens in your browser — your document is never uploaded to any server.

Three Ways to Create Your Signature

Draw Your Signature

The draw mode provides a smooth canvas that works with mouse, trackpad, touchscreen, or Apple Pencil. PDFJolt uses quadratic Bezier curves for natural-looking handwriting — not jagged straight lines between points. Your signature is exported as a transparent PNG, so it blends naturally onto any document background.

Type Your Signature

If you prefer a typed signature, enter your name and choose from four professional script fonts: Dancing Script (elegant), Great Vibes (formal), Pacifico (casual), and Caveat (handwritten). Each font is rendered at high resolution for crisp results even on printed documents.

Upload Your Signature

Already have a signature image? Upload a PNG, JPG, or SVG file. PDFJolt can automatically remove the white background, making your signature look like it was drawn directly on the document rather than pasted from an image.

Placing Your Signature

After creating your signature, PDFJolt renders the full PDF so you can see exactly where your signature will appear. Click "Add Signature" to place it, then drag to position it precisely. Resize handles let you adjust the size while maintaining the correct aspect ratio. Navigate between pages to add signatures to multiple pages — common for contracts that require initials on every page.

You can also add a date stamp next to your signature with one click. The date is formatted in a professional style and can be dragged to any position on the page.

Common Use Cases

Freelance Contracts

Freelancers receive contracts via email daily. With PDFJolt, you can sign and return a contract in under 60 seconds — no printing, no scanning, no paid subscription. Your client gets a professionally signed PDF that looks exactly like a wet-ink signature.

Employment Documents

New hire paperwork, offer letters, NDAs, and tax forms (W-4, I-9) all require signatures. PDFJolt lets you sign them all from your phone or laptop without creating accounts on multiple e-signature platforms.

Real Estate & Leases

Lease agreements, rental applications, and property disclosures often need signatures on multiple pages. PDFJolt's multi-page signature placement makes this effortless.

School & Permission Forms

Parents signing school permission slips, field trip forms, and report cards can do it in seconds from their phone instead of printing, signing, and sending back physical paper.

Privacy & Security

Every major e-signature platform — DocuSign, Adobe Sign, HelloSign, PandaDoc — uploads your documents to their cloud servers. Your contracts, financial records, and personal documents pass through third-party infrastructure. PDFJolt is fundamentally different: your PDF is processed entirely in your browser's memory using pdf-lib, an open-source PDF manipulation library compiled to WebAssembly. No server receives your file. No cloud storage. No data collection. No account required.

Your signature can optionally be saved in your browser's localStorage for convenience — but this is entirely local storage on your device, never transmitted anywhere.

Tips for Best Results

• For the most realistic signature, use the draw mode with a stylus or Apple Pencil on a touchscreen device.
• If drawing with a mouse, draw slowly and deliberately — PDFJolt smooths the curves automatically.
• Use the "Save signature for next time" checkbox to avoid redrawing your signature on future documents.
• Add a date stamp next to your signature for legally dated documents.
• For multi-page contracts, navigate to each page that needs a signature and add one per page.
• The signature is embedded as an image in the PDF — it will look the same on any device or when printed.
