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.
