About this tool

Split PDF by Bookmarks, Blank Pages or QR Codes

Cut a PDF into chapters at its bookmarks, or a scanned stack into documents at blank or QR-coded separator sheets. Everything runs locally in your browser — no upload, no sign-up, no watermark and no file size limit.

One File per Chapter

Every bookmark starts a new PDF named after its title. Pick level 1 for chapters or a deeper level for sections; each file keeps the bookmarks of its own chapter.

Scanned Stacks, Sorted

Put a blank sheet between documents before scanning, and Toolula splits the scan wherever it finds one. The separator pages are left out unless you keep them.

QR Code Separator Sheets

Print a separator sheet with a QR code or barcode such as SPLIT-Invoice-42. The scan is cut at every sheet, and the code text can name the next file.

How to use it

  1. Drop the PDF. The Split tab opens with At bookmarks selected; pick At blank separator pages or At QR code / barcode sheets for scans.
  2. For bookmarks, choose the level to split at. The list shows every part with its file name and pages.
  3. For blank or QR separators, every page is shown as a thumbnail with the separators marked. Adjust the sensitivity or code text, and click a page to add or remove a cut.
  4. Click Split and download one ZIP with all parts, or each part on its own.

Frequently asked questions

Are my PDFs uploaded to a server?

No. Toolula processes the document inside your browser tab with pdf-lib and WebAssembly, so the file never leaves your device.

What happens to pages before the first bookmark?

The cover and table of contents become the first part, named after the original file, so no page is lost.

Which codes can mark a separator sheet?

QR codes, Data Matrix codes and Code 128 or Code 39 barcodes. Leave the code text empty to split at any code, or enter a pattern such as SPLIT-* so other codes on your documents are ignored.

Can I just remove the blank pages instead?

Yes. Remove Blank Pages uses the same detection and deletes empty pages without splitting the file.

Is it really free?

Yes. You can use every Toolula PDF tool for free, without an account. The free plan has fair-use limits; Toolula Pro, an optional plan, raises them and adds advanced features.
