Portals reject anything over 10 MB. Email chokes at 25. The usual fix is mailing your lease to a server farm. This one runs in the room your documents never leave — turn off your Wi-Fi and it still compresses.
Most PDFs are heavy because of oversized images and embedded baggage. BlackoutPDF re-renders every page at the resolution you pick and rebuilds a brand-new PDF from those pixels — like running your document through a very good scanner.
The honest trade-off: the output is made of images, so text is no longer selectable. That's how it gets small — and as a bonus, the original metadata, edit history, and hidden layers don't survive the rebuild.
And because every byte of this happens inside your browser tab, there is no upload to intercept and no "files deleted after 2 hours" policy to take on faith. The court portal gets a smaller file. Nobody else gets anything.
Free for small jobs · $19/year unlocks everything — batch compress, Auto-Redact, the signature library, Bates stamping, every tool, unlimited, on all your devices. Team is $99/year for your whole team. 30-day refund, no questions.
Your browser does everything. The PDF is decoded in memory, each page is re-rendered to pixels at your chosen resolution, re-encoded as JPEG, and assembled into a new PDF — all in this tab. You can verify it: open DevTools → Network, compress a file, and watch zero requests carry your data. Or just turn your Wi-Fi off first.
No — and we'd rather tell you that than hide it. The compressed PDF is built from page images, like a clean scan, which is exactly how it gets dramatically smaller. If you need the text layer preserved, keep the original for editing and use the compressed copy for sending.
It depends on what's inside. Scans and image-heavy PDFs routinely shrink 60–90% on the Email preset. Files that are already tightly optimized may shrink little — and if the result somehow comes out larger, we'll say so plainly and still let you download it. No fake progress bars, no inflated "savings."
The free tier compresses documents up to 10 pages, forever. Pro is $19/year and unlocks everything — unlimited pages, files and documents across all five tools, plus every superpower: batch compress on this page, Auto-Redact, batch convert, the signature library, and Bates stamping, on every device you own. That's less than one month of Acrobat Pro, with nothing held back. Team is $99/year and covers your whole team with one license key, commercial-use rights, and priority support. Prefer not to subscribe? A one-time $49 Pro Lifetime license unlocks everything forever — no recurring charge. No account either way — your license key is your receipt.
Drop several PDFs at once (a Pro feature) and each one is compressed right here in this tab with the preset you picked — same pipeline as a single file, just run back to back. The outputs are then bundled into compressed.zip in your browser's memory and handed to you as a download. Zero files leave the room; open DevTools → Network while it runs if you want the receipts.
Where your browser supports the new WebMCP standard (navigator.modelContext — Chrome and Edge today), an AI agent can run this page for you — pick a quality preset, compress, and download — by calling the same in-tab actions the buttons do. You open the file yourself, and it never leaves the tab. On browsers without WebMCP the feature isn't there. We deliberately offer no agent API that uploads your file.
The free tier compresses documents up to 10 pages. Pro unlocks unlimited everything for less than one month of any competitor's subscription.
