Split PDF by Bookmarks

Long annual reports, bundled bank statements, and compiled legal binders often include a table of contents with PDF bookmarks already set. Splitting on those markers is faster than manually typing page ranges for each chapter.

Siliph Split by Bookmarks reads the document outline in the browser-backed engine and exports one PDF per top-level bookmark by default. Nested bookmarks can be included when you need finer granularity, such as splitting a tax workbook by worksheet.

Output filenames inherit bookmark titles where possible, which keeps downstream filing consistent in SharePoint, Google Drive, or local matter folders. Each child file remains a standard PDF compatible with Adobe Reader and mobile viewers.

Encrypted uploads protect multi-client bundles during splitting. Files auto-delete within two hours on the free plan, and bookmark splitting requires no Siliph account to try on a sample document.

If bookmarks are missing, use Split by Text or manual range Split PDF instead; run Create Bookmarks first when you want to define sections before splitting.

Siliph split tools divide PDFs by range, bookmark, size, or text trigger entirely in the browser with encrypted transfers at each step. Generated parts are auto-deleted within two hours on the free plan, and splitting starts immediately without signup.
