Stamp "1 / N" or "Page 1 of N" in any corner, with cover skip.

View and edit title, author and more, or wipe it all in one click.
Physically delete metadata, comments and hidden content before sharing.
Reorders pages for duplex printing and folding, with gutter margins.

Why local matters
Your contracts, tax forms, medical records and manuscripts have all spent time on a stranger's server — even when they promise to "delete after 1 hour", you can't verify it.
OctopusPDF runs the entire pipeline in your browser tab. Our servers physically cannot receive your file. Don't take our word for it: press F12 → Network → convert a file → count the upload requests. There are none.
Bring your own key
When summarizing or translating, both your PDF and your API key stay inside your browser. Our servers never see either.
Parsed inside your browser tab with pdf.js. No PDF bytes are ever uploaded to OctopusPDF.
Stored only in your browser's localStorage. Our backend has no /api call that receives it.
Your browser connects directly to the OpenAI-compatible endpoint you entered. We do not proxy the request.
Made for real workflows
Same tool, different jobs — every workflow below runs 100% in the browser, nothing uploaded.
