Pages are copied unchanged in every mode, so text stays selectable and scans keep their resolution. On Pro, files above 200 MB open in big-file mode, which streams the document and splits by page count with a few megabytes in use. Nothing is uploaded, and the original is never modified.
How it works
- Open Bindery in Firefox or Chrome and drop the PDF into Split
- Choose every page, every N pages, at bookmarks, or under a size
- Download all the parts as one ZIP
Questions people ask
Can it split under a size limit?
Yes. Choose “Under a size”, type the limit, and Bindery writes and measures each part so every file stays below it — the quick way to meet a mail or portal cap.
How is this different from pdfseparate?
pdfseparate writes one file per page and nothing else. Bindery adds even chunks, chapters at bookmarks named after their titles, and parts under a size limit, previews the plan on a page board, and delivers everything as one ZIP without touching the page content.
Is the browser version any slower than the tools in my repos?
For ordinary documents the difference is not noticeable; the work runs in a background worker inside the browser. Very large scans stream in big-file mode rather than loading whole, so memory use stays low even on a modest machine. Any job can be cancelled midway.
