FAQ
Comma-separated, e.g. 1-3,5,7-9 — each range becomes one output file. Invalid ranges are reported before any quota is used.
Try it ↑Yes — choose "every N pages" mode; a 10-page file split every 2 pages yields 5 files.
Try it ↑The PDF is split at the start pages of its top-level bookmarks (outline), one file per chapter. Files without bookmarks get a clear message and no quota is used.
Try it ↑Pages are grouped by estimated cumulative size — the file is only split, never re-compressed, so parts may vary slightly. If a single page already exceeds the target we say so honestly; compress the PDF first to shrink it.
Try it ↑No. Splitting runs locally in your browser.
Try it ↑No. Any change to a signed PDF (merging, compressing, watermarking…) invalidates the existing digital signature — that is the tamper-proof design of PDF signatures, not a limit of this site. Process first, then sign.
Try it ↑Yes — and you can verify it: the tool runs on open-source in-browser engines (pdf-lib, pdf.js, Tesseract OCR…) on your own device. Open DevTools → Network while processing and you will see no file upload requests.
