How to Split a PDF into Multiple Files

Choose a split strategy based on whether your boundaries come from page groups, individual pages, overlapping lengths, or approximate file size.

Focus
Range, Page, and Size categories

Up to 100 output files
Tip
Multiple results download as ZIP

Choose a split category

Range creates page groups, Page separates every or selected pages, and Size targets approximate parts in KB or MB.

  • Custom: define from-to ranges
  • Fixed: repeat a page count
  • Select: build visual output batches
  • Length: create overlapping ranges of a chosen length

Understand output grouping

Examples make the boundary rules easier to verify before processing.

  • Custom 1-3; 4-6 creates two outputs
  • Fixed 3 creates consecutive three-page groups
  • Every Page creates one PDF per source page
  • A request cannot exceed 100 outputs

Split versus Extract

Split creates several outputs, while Extract normally keeps selected pages together in one new PDF.

  • Use Split for chapters or repeated batches
  • Use Extract for one focused selection
  • Use Size when upload limits matter more than page boundaries

Common split mistakes

Incorrect delimiters, excessive output counts, and choosing the wrong category are the usual causes of surprising results.

  • Review the visual groups
  • Remember that multiple results use ZIP
  • Do not assume size targets produce byte-exact parts
