Large PDFs are awkward. They are slow to open, too big to email, and force the reader to scroll through material that has nothing to do with them. Splitting solves all three problems at once by dividing a single document into smaller, self-contained files. Upload your PDF, choose where the divisions should fall, and download the parts — free, instant, and with no software to install.
The most common reason is relevance. A hundred-page annual report might contain one section the finance team needs and another for operations. Sending each team only their part respects their time and avoids the risk of them reading something not meant for them.
File size is the second reason. Email systems commonly reject attachments over ten or twenty-five megabytes, and a heavily illustrated document passes that easily. Splitting into parts that individually fit under the limit is often simpler than compressing the whole thing.
Structure is the third. Scanned archives, bound reports, and multi-chapter manuals are frequently digitised as one enormous file. Breaking them into logical units makes the material navigable and much easier to catalogue.
These three operations overlap enough that people often reach for the wrong one.
Split divides a document into several output files. Use it when you want each part to exist separately — chapters as individual PDFs, for instance.
Extract Pages pulls a chosen selection into one new file and discards the rest. Use it when you only care about a specific section and have no interest in the remainder.
Delete Pages keeps everything except the pages you name, returning a single file. Use it when the document is nearly right and just contains a few pages that need removing.
Upload your PDF by dragging it onto the box or clicking to browse. Choose your split method: divide at specific page numbers to control exactly where each break falls, or split into fixed-size chunks when you simply need evenly sized parts. Confirm the ranges look right, then download. If the operation produced more than one file, they arrive together in a ZIP.
Teachers separate a textbook scan into per-chapter readings for each week of a course. Accountants break a combined statement file into one document per client or per month. Legal teams divide bundled exhibits so each can be filed and referenced independently. Publishers and print shops separate a manuscript into sections for different reviewers. Anyone digitising an archive splits a long continuous scan into individually catalogued records.
Every page in the output is copied from the source rather than rebuilt. Embedded fonts remain embedded, so text renders identically and stays fully selectable and searchable. Vector graphics stay sharp at any zoom level. Photographs keep their original resolution with no additional compression. The split files together contain exactly what the original did, just distributed across several documents.
Encrypted documents are supported directly. If your file needs a password, a prompt appears automatically after upload — enter it once and the split proceeds as normal. To strip the password permanently instead, run the file through Unlock PDF first.
Your document is processed in memory and discarded as soon as your download completes. Nothing is written to disk, nothing is logged, and no copy is retained. The tool runs in any modern browser on Windows, macOS, Linux, Android, and iOS with nothing to install.
To rejoin files later, use Merge PDF. For visual control over which pages go where, Organize PDF shows every page as a thumbnail you can reorder and remove. Compress PDF shrinks the parts further if they still need to be smaller.
