The split tool offers three modes of operation: extract every page as a separate file, split at specified page numbers, and extract custom ranges.
Custom range specification supports both individual pages and ranges. For example, entering 1,3,5-10,15-20 would extract those specific pages.
For recurring split patterns, templates can be saved and reused. This is useful for processing batches of similar documents.
The tool also supports splitting by file size, which divides a large PDF into chunks that each stay below a specified maximum size.
