Split PDF

The Split PDF tool divides one PDF into separate files using three strategies: explode every page into its own single-page PDF, cut out a contiguous page range, or chunk the document into fixed-size groups of pages. After loading a file, the tool reads its page count and builds a plan preview listing every output file, its page span, and the exact filename it will receive — document-page-3.pdf for singles, document-pages-2-5.pdf for ranges and chunks. The "Split into N files" button runs the job, and a generated files list appears with a Save button per file plus Download all for the batch. Each output is a valid PDF built with pdf-lib, and the source stays untouched on disk. Password-protected documents are rejected with a clear message rather than producing broken output. Splitting locally matters when documents are sensitive — contracts, medical records, bank statements — since nothing is uploaded. For anyone who needs to email one page of a 40-page statement, separate a merged scan, or break a long deck into presentable sections, this browser-based PDF splitter does it in seconds without installing software.

1. 1

   Click "Choose PDF" or drop a file onto the upload area and wait for the page count.

2. 2

   Pick a "Split mode": Every page, By page range, or By page count (chunks).

3. 3

   For range mode, set Start page and End page; for chunk mode, set Pages per chunk.

4. 4

   Review the plan preview — each row shows the label, output filename, and page count.

5. 5

   Click "Split into N files", then use Save per file or Download all.

• Emailing a single page from a 40-page bank statement without sending the rest.
• Separating a scanned bundle of mixed documents into individual files.
• Breaking a quarterly report into per-department sections for distribution.
• Extracting just the cover page of an ebook for a product listing.
• Preparing a multi-page contract so each party signs a one-page copy.
• Chunking a long slide deck into 10-page uploads for a size-limited portal.

• Check the plan preview carefully — filenames reveal exactly what each chunk contains.
• Use chunk mode for uniform splits and range mode for precise extraction.
• For very large documents, split into smaller batches to keep memory use down.
• Keep the original PDF; splits are copies, but re-downloading beats re-splitting.
• Name your source file well, since output names inherit the base name.

• The Mode stat confirms which strategy is active at a glance.
• Plan preview rows double as a checklist before you click split.
• Download all only includes chunks that finished without errors.
• Switch modes after loading — the plan recalculates instantly.
