Split a PDF

Split one PDF by fixed page count, custom ranges, or auto-detected blank separator pages.

Splitting is the opposite problem — one big PDF that should be several. The standout mode auto-detects blank separator pages: if your scanner dumped a whole stack of documents into one file with blank sheets between them, Docexp finds those blanks and splits there, giving you one clean PDF per document instead of counting page numbers by hand.

How Split a PDF works

  1. Drop your file into the tool, or click to browse.
  2. Everything runs in your browser — no upload, no server, no waiting.
  3. Download your result straight to your device.

Good to know: Three modes: a fixed page count, explicit page ranges, or blank-page auto-detection. Blank detection measures how much of each page is non-white, so a genuinely empty sheet splits cleanly while a page with a faint stamp or a signature is not mistaken for a separator.

Common questions

How does the blank-page split decide where to cut?

It renders each page and measures how much of it is non-white. Pages below a low threshold are treated as blank separators, and the document is split at each one.
