Draw or type your signature, place it on the page, download. The file never leaves this tab — and unlike "free" e-sign sites, the original text layer is preserved byte for byte.
Think about what's actually in the PDF you "sign online": your full legal name, your address, what you earn, what you owe, who you're doing business with. Upload-based e-sign tools receive all of it, store it on their servers, and ask you to trust a retention policy you've never read.
BlackoutPDF signs the document inside your browser tab. There is no server copy to breach, no "processed file" to delete, no signature image saved in someone else's database, ready to be reused.
And the export is lossless: your signature is stamped into the original PDF with its text layer intact. The document stays searchable, selectable, and exactly as your counterparty sent it — plus your ink.
Free for small jobs · $19/year for unlimited · $4.99/month for the Signature Library and every other superpower — Auto-Redact, batch processing, Bates stamping. Every plan covers Sign, Redact, Merge, Compress and Convert on all your devices. 30-day refund, no questions.
In most jurisdictions, yes — laws like the U.S. ESIGN Act and the EU's eIDAS regulation recognize simple electronic signatures (a drawn or typed mark placed with intent to sign) for most everyday agreements. Some documents — wills, certain notarized filings — have stricter requirements, and some workflows need certificate-based audit trails. This is general information, not legal advice: if the stakes are high, ask a lawyer.
Because a contract is concentrated sensitive data — identity, money, terms — and an upload creates a copy outside your control. Every server copy is a thing that can be breached, subpoenaed, retained "for quality purposes," or quietly kept past the deletion date. Here there's nothing to retain: the file is opened in your browser's memory and never transmitted. Turn off your Wi-Fi after the page loads — signing still works.
Yes. Signing here is lossless: we load your original PDF bytes and stamp the signature image onto the page — the text layer, links, and form structure are untouched, so the document stays searchable and selectable. (Our Redact tool is the deliberate opposite: it flattens pages to pixels so removed content can't be recovered. Different jobs, different physics.)
The free tier signs documents up to 3 pages, forever. Plus — $19 a year — removes every page, file, and document limit on this and all five BLACKOUT//PDF tools, on all your devices. Pro — $4.99 a month — is everything in Plus, plus the weekly-workflow superpowers: the Signature Library here, Auto-Redact, batch processing, and Bates stamping. A full year of Plus costs less than one month of Acrobat Pro. 30-day refund either way. No account — your license key is your receipt.
In your browser's local storage, on your device — saved as a small transparent PNG. It is never uploaded, never synced, never seen by us; there's no signature image sitting in someone else's database. Pro lets you keep up to five saved signatures and stamp them onto any contract in two clicks instead of redrawing. Clear your browser data and they're gone — which is exactly the point.
Save up to 5 signatures and reuse them on any contract — no redrawing. A Pro tool, stored only in this browser.
Drawn locally. Your signature never leaves this tab — not even to us.
Stamped in plain monospace — edit it however your contract wants it.
The free tier signs documents up to 3 pages.
