About this tool
Split PDFs by page, fixed batches, custom ranges, extraction, or page removal with browser-side ZIP/PDF export.
PDF Split Tool breaks one PDF into separate files using five modes — one file per page, fixed batches of N pages, custom semicolon-separated page groups, extract selected pages into a single PDF, or remove selected pages and keep the rest. It shows the output plan, file by file, before anything is generated (the first 80 planned files are listed on screen; the full plan is still exported even for larger splits), then downloads a single PDF or a DEFLATE-compressed ZIP containing every part plus a split-plan.txt manifest. Page selections accept ranges such as 1-3, 7, 10-12.
Open PDF Split Tool on AltFTool — it loads instantly in your browser.
Press Choose PDF to load your file, then pick a mode: Every Page, Fixed Batches, Custom Groups, Extract Pages or Remove Pages
Type pages as ranges like 1-3, 7, review the file-by-file output plan shown before anything is generated, then press Split PDF
One output downloads as a single PDF; multiple parts download as a ZIP of numbered PDFs plus a split-plan.txt manifest
The first 80 planned output files, their labels and page numbers are listed on screen first (the full plan is still exported even for larger splits), so you catch a wrong range before generating anything.
Per-page, fixed batches, custom groups, extraction and removal all work off the same page-range syntax instead of needing separate tools.
Multi-file results are packaged as a ZIP with a split-plan.txt manifest recording the mode and the pages inside each file.
Choose the Every Page mode: it plans one output PDF per page, so a 30-page file produces 30 PDFs delivered in a single ZIP with sequentially numbered filenames.
Comma-separated single pages and hyphenated ranges, for example 1-3, 7, 10-12. Pages outside 1 to the document's page count are rejected with a message naming the invalid entries. Custom Groups mode separates one output file from the next with a semicolon.
A single PDF downloads directly when the plan produces exactly one output — as Extract and Remove modes normally do. Two or more outputs are packaged into a DEFLATE-compressed ZIP along with the plan manifest.
Yes. Remove mode keeps every page except the ones you list and exports the remainder as one PDF. It will not let you remove every page — at least one must remain.
