Click the upload area or drag and drop your file. Upload your PDF and choose whether to split into individual pages or fixed-page chunks (e.g. every 5 pages), then download all parts as a ZIP.
Adjust the tool options to match your requirements — all settings are explained with helpful labels and previews where applicable.

You can split a PDF in three ways: (1) Split into individual pages — each page becomes a separate PDF file; (2) Split into fixed-size chunks — e.g. every 5 pages produces a series of 5-page PDFs; (3) Split at specific page numbers — enter the page numbers where splits should occur (e.g. 5,10,20 splits the document at pages 5, 10 and 20, producing four PDFs). All output files are packaged into a single ZIP for easy download.
Output files are named based on the original filename plus the page range they contain. For example, splitting "report.pdf" into individual pages produces "report-page-1.pdf", "report-page-2.pdf" etc. Splitting into chunks produces "report-pages-1-5.pdf", "report-pages-6-10.pdf" etc. This naming makes it easy to identify which part of the original each file represents when working with the downloaded ZIP.
There is no imposed limit — the only constraint is your browser's available RAM. A 500-page PDF split into individual pages will produce 500 separate PDF files, all bundled into a ZIP. For very large documents, the ZIP generation may take a few seconds. In practice, PDFs up to 1,000 pages and several hundred MB have been processed successfully. Very large files may be slower on lower-spec devices.
No — splitting is a completely lossless operation. Each page's content — text, images, fonts, vector graphics and embedded objects — is transferred directly from the source file without any re-rendering, re-compression or quality loss. The output files are identical in content quality to the corresponding pages in the original document.
Absolutely — this is a common workflow. Split the PDF to isolate sections, discard or work on the parts you need, then use our PDF Merger tool to recombine the desired sections in any order. This gives you precise control over restructuring complex documents — reordering sections, removing chapters, or creating customised versions from a master document.
No — password-protected PDFs cannot be split without first removing the password. Use our Unlock PDF tool with the document password to unlock the file, then return to the PDF Splitter. PDFs that have permissions restrictions (copying/printing disabled) but no open password can typically be split without unlocking, since the content is accessible even if certain user actions are restricted.
Bookmarks (PDF outlines/navigation tree) that point to pages within each split's page range are preserved in the corresponding output file. Bookmarks pointing to pages outside the split are omitted. This means each split file retains the relevant portion of the original navigation structure, making split files independently navigable without requiring the parent document.
Automatic chapter-boundary detection is not available — you need to know the page numbers where chapters start. To find these, open the PDF in your reader, navigate to each chapter start using the bookmarks/outline panel, and note the page numbers. Then enter those page numbers as split points. This gives you complete control and ensures splits occur exactly at the boundaries you intend.
Yes — form fields on each page are preserved in the split output files. However, form field values that depend on calculations referencing fields on other pages (cross-page calculated fields) may not update correctly after splitting. It is best practice to flatten form fields (convert to static content) before splitting if the form uses complex cross-page logic.
No — all splitting and ZIP generation is performed entirely within your browser. Your PDF is processed locally using the PDF-lib and JSZip JavaScript libraries. Nothing is transmitted to any server. This is especially important for confidential business documents, legal files and personal records. No login is required and no file data is retained after you close the tab.
