How we handle your data

Split PDF by Size

Split a PDF into consecutive parts that each stay under the size you set, for example an email attachment limit. File names show each part's pages.

Six A4 pages, each with an image of about 0.9 MB that cannot be compressed. With a 2 MB limit the ZIP should hold three parts of two pages; each name shows its pages.

A practical guide

Split PDF by Size: a worked example

  1. Choose one PDF of up to 60 MB and 500 pages.
  2. Set the maximum size of each part, for example your email attachment limit.
  3. Split it and unpack the ZIP; each file name shows its page range.

Try this example

Split the sample with a 2 MB limit: its six image pages of about 0.9 MB each give three parts of two pages, named with their page ranges.
