The Complete Guide to Digital Signatures
Create, save, and use professional e-signatures anywhere.
In today's fast-paced digital world, printing a document just to sign it with a pen feels like using a fax machine to send an email. Whether you're closing a business deal from your home office, signing an NDA while traveling, or approving a contract on your phone—you need a digital signature that looks professional and works everywhere.
Our Digital Signature Generator Pro is the most advanced free tool for creating electronic signatures. Unlike basic signature makers, we offer velocity-sensitive drawing that mimics real ink flow, 15 handwriting fonts, transparent PNG export, and a signature library to save your creations. Best of all? Everything runs in your browser—your signature never touches our servers.
What Makes This Signature Tool Different?
Velocity-Sensitive Pen

Electronic vs. Digital Signatures: Legal Guide
While the terms are often used interchangeably, there's an important legal distinction:
Electronic Signature (e-Sign)
Any electronic mark indicating intent to agree—including a signature image, clicking "I Accept," or typing your name. This tool creates e-signatures.
Digital Signature (Cryptographic)
A cryptographic mechanism using certificates that verifies document authenticity and signer identity. Required for government submissions.
Pro Tips for Better Signatures
- • Use Blue Ink for Legal Documents: Banks and lawyers prefer blue because it distinguishes originals from black-and-white copies.
- • Sign Quickly: Our velocity engine creates thinner lines for faster strokes—mimicking natural pen behavior. Quick signatures look more authentic.
- • Use Transparent PNG: Export as PNG with transparent background so your signature overlays documents without white boxes.
- • Enable Auto-Crop: This removes empty space around your signature, creating a tighter, more professional bounding box.
- • Save Multiple Versions: Create different signatures—one formal, one casual, one initials-only—and save all to your library.
- • Use Touch Devices: Signatures made with a finger on a phone/tablet or a stylus on an iPad look more natural than mouse-drawn ones.
Frequently Asked Questions
How do I add my digital signature to a PDF?
Download your signature as a transparent PNG. Then open your PDF in any editor: Adobe Acrobat (Insert > Image), Mac Preview (Tools > Annotate > Signature), Google Chrome PDF viewer, or free tools like SmallPDF and PDFescape. Place the signature image on the signature line.
Is a typed signature legally valid?
Yes! Under the US ESIGN Act, EU eIDAS, and similar laws worldwide, the visual form of a signature matters less than the intent to sign. Typing your name with a cursive font is legally equivalent to drawing it, as long as you intend to be bound by the document.
Why should I use blue ink for signatures?
Blue ink has been traditionally preferred by lawyers and banks because it makes it easy to distinguish an original 'wet' signature from a black-and-white photocopy or scan. While not legally required, it's a professional convention.
What's the difference between PNG and JPG export?
PNG supports transparent backgrounds—perfect for overlaying on documents without a white box. JPG always has a white background but produces smaller file sizes. Use PNG for signatures on documents, JPG for web use where file size matters.
How does the velocity-sensitive drawing work?
Our pen engine calculates the speed of your mouse/finger movement. Fast strokes create thin lines (like quickly crossing a T), while slow strokes create thick lines (like pressing down at the start of a letter). This mimics natural ink flow from a fountain pen.
Is my signature data private and secure?
100% private. This tool runs entirely in your web browser using client-side JavaScript. Your signature is drawn on a local HTML5 canvas and converted to an image by your browser. No data is ever sent to our servers. It even works offline.
What is the Signature Library?
The library lets you save unlimited signatures to your browser's local storage. Once saved, you can quickly access, copy to clipboard, or delete signatures without redrawing. Perfect for people who need consistent signatures across documents.
What export sizes are available?
Four sizes: Small (600×300px), Medium (900×450px), Large (1200×600px), and Extra Large (1800×900px). Larger sizes are better for print documents and high-resolution displays. The auto-crop feature removes empty space regardless of size.
Can I use this on mobile devices?
Absolutely! The tool is fully responsive and supports touch input. Signing with your finger on a smartphone or tablet often produces more natural-looking signatures than using a mouse. For best results, try signing on an iPad with an Apple Pencil.
How many fonts are available for typed signatures?
We offer 15 carefully curated handwriting and cursive fonts: Dancing Script, Great Vibes, Sacramento, Parisienne, Allura, Alex Brush, Italianno, Tangerine, Pinyon Script, Herr Von Muellerhoff, Marck Script, Satisfy, Kaushan Script, Lobster Two, and Caveat.
What is auto-crop and should I use it?
Auto-crop automatically detects the signature content and removes empty space around it, creating a tighter bounding box. This is recommended for most uses as it produces cleaner signatures that fit better on document signature lines.
Can I create multiple signatures for different purposes?
Yes! Many users create a formal full signature, a casual short signature, and initials for different document types. Save each to your library and access them with one click whenever needed. There's no limit to how many you can save.
