MyDigitSign Features

Everything you need to sign PDFs and documents online — free, private, and directly in your browser. No uploads to any server. No account required. No hidden fees.

Core Features

MyDigitSign is a comprehensive, client-side electronic signature utility. Every feature below runs entirely in your browser — your documents never leave your device.

3 Signature Creation ModesDraw your signature freehand with your mouse, trackpad, or touchscreen. Type your name and choose from beautiful cursive script fonts (Dancing Script, Pacifico, Great Vibes, Caveat). Upload an existing PNG or JPG image of your handwritten signature. All three modes output high-resolution transparent PNGs.
PDF & Image Document SigningSupports standard PDF documents and image files (PNG, JPG, JPEG) up to 10MB. Upload, preview every page in high resolution, and place your signature on any page of any document. The tool uses pdfjs-dist for rendering and pdf-lib for merging — all locally in browser memory.
Interactive Drag-and-Place OverlayDrag your signature overlay across any area of the document page. Use the bottom-right corner drag handle to resize it proportionally. Navigate between pages with intuitive page controls. Your signature stays precisely where you placed it on every page.
Certificate-Based Digital Signing (.pfx / .p12)For documents requiring cryptographic proof of integrity, upload your own .pfx or .p12 digital certificate. MyDigitSign embeds a cryptographic signature into the PDF structure entirely in-browser — providing tamper-evident, legally verifiable signed documents. Free guide: How to get a free certificate →
Light & Dark ThemeSeamlessly toggle between a premium dark-mode interface and a clean, high-contrast light theme with a single click. The preference is saved locally via localStorage and automatically matches your system's prefers-color-scheme setting on first visit.
Instant Native SharingAfter signing, share your document directly via your operating system's native Web Share API — send it to WhatsApp, Slack, Mail, Messages, or any other app on your phone or desktop without leaving the page. No manual file management required.
100% Client-Side ExecutionThis is the most important feature. Your PDF, your signature, and your personal data never touch our servers. Ever. All processing happens in your browser's memory using local JavaScript APIs. When you close the tab, everything clears. Zero data retention, zero server logs, zero privacy risk.
Fully Mobile ResponsiveSign documents on any device — iPhone, iPad, Android phone, or tablet. The drawing canvas responds to touch gestures, the signature overlay is draggable via touch, and the interface adapts to every screen size. No app download needed — it works right in your mobile browser. Full guide: Sign PDF on iPhone & Android →
Instant Download — No WaitingBecause everything runs locally, there's no upload time and no server processing queue. Click Download and your signed PDF saves to your device immediately — typically in under 1 second regardless of your internet speed.

Frequently Asked Questions

Is MyDigitSign really 100% free?

Yes. There are no subscription plans, no per-document fees, no watermarks, and no paywalls. MyDigitSign is, and will remain, completely free for all users. We support the service through non-intrusive display advertising.

Why doesn't MyDigitSign require an account?

Because you don't need one. Since all processing happens locally in your browser, there's no data to store on our servers and no reason to create a user profile. Open the site, sign your document, download it — done.

How is this different from DocuSign or Adobe Sign?

DocuSign and Adobe Sign are enterprise-grade platforms that upload your documents to their cloud servers, require accounts, and charge monthly subscriptions. MyDigitSign is a privacy-first, client-side alternative that processes everything locally in your browser at no cost. It's ideal for individuals and small businesses who need simple, secure, free signing without cloud dependencies.

Is MyDigitSign legally binding?

Yes. Electronic signatures created with MyDigitSign are legally binding under the ESIGN Act (USA), UETA, eIDAS (EU), and equivalent laws in 180+ countries for most commercial and personal agreements. Read the full breakdown: Are Electronic Signatures Legally Binding? →

What browsers does MyDigitSign support?

MyDigitSign works in all modern browsers — Chrome, Firefox, Safari, Edge, and Brave — on both desktop and mobile. It requires JavaScript and HTML5 Canvas support, which all modern browsers provide by default.

Can I sign multiple documents in one session?

Yes. You can sign as many documents as you need in a single browser session. Simply upload a new document after downloading your signed PDF and repeat the process. There are no daily limits.
