Say which pages in plain notation
Type 1-3, 7, 12- and you get pages one to three, page seven, and everything from twelve to
the end. Duplicates are ignored and out-of-range numbers are dropped rather than throwing an error at
you. Or switch the mode and get every page as its own numbered file.
The pages come out untouched
Pages are copied object by object into a new document, not re-rendered. Text stays selectable, vector graphics stay sharp, and a page that was 300 dpi still is. The only thing that changes is which pages are present and, if you asked for it, their rotation attribute.
Password-protected files are refused, not guessed
If a PDF is encrypted, this tool says so and stops. It does not attempt to break the password. Open it in a reader you already trust, save an unprotected copy, and split that.
Nothing is uploaded
The PDFs people split are bank statements, contracts and scanned ID. Every mainstream tool wants those on its server. This page has no server: the parser runs in your browser, and the page's security policy blocks any connection to anywhere but this site. Here is how that is enforced.
All HermitFile tools
Every one of them runs in your browser. Nothing you open is uploaded.
