Split PDF

Split takes one PDF apart into several files, and gives you three ways to decide where the cuts fall. By range reads ordinary page notation — 1-5, 8, 11-13 becomes three files. Selected pages lets you click thumbnails in the grid. Every page produces one single-page PDF per page, bundled into a ZIP so you are not downloading thirty separate files.

Every mode works on page boundaries only. Each output file is assembled by copying the chosen pages as-is, so fonts, images and searchable text come through unchanged. A 200-page manual split into chapters this way produces chapter files that open in any reader, with no re-compression step in between.

Ranges are validated before anything runs: a range that counts past the last page, or a segment like 5-2, stops with a clear message instead of a partial output. Overlapping ranges are allowed — you may genuinely want pages 1-5 and 3-7 — and the tool notes the overlap on the result card so nothing happens silently.

The run happens entirely in the worker on your device: reading the file, validating ranges, copying pages, packing the ZIP. Nothing uploads, the network panel stays quiet throughout, and closing the tab clears everything. Splitting a document never modifies the source — every output file is a new document, so you can split the same original five different ways and still have the original.

What splitting deliberately does not do: it does not recognize content (a chapter boundary is a page range you name, not something the tool infers), it does not run OCR on scanned pages, and it does not reduce quality — pages are copied, not re-rendered. Output files carry your file's name with -part-N; a many-file split arrives as one ZIP with -split appended, so the outputs identify themselves on disk.

Consider a 48-page grant report where the funders want the narrative and the budget as separate files. Open it here, type 1-31 in the range box for the narrative, add a second segment 32-48 for the budget, and download the ZIP: two PDFs, each opening exactly where its section began, text still selectable, the original untouched for the archive copy. The whole exchange with the tool is one text box and one button. And because the original report still exists untouched, re-splitting next quarter when the funders change their mind costs another thirty seconds and nothing else.
