About this Split PDF by File Size workflow

What it does

Split a PDF into contiguous page groups sized around a chosen maximum in MB, useful when a portal rejects large uploads and page order must stay intact.

Processing model

This focused tool processes the selected document in your browser. The source file is not overwritten.

Good practice

Keep the original file and inspect the downloaded result before replacing an archival, signed, submitted or legally important copy.

How Split PDF by File Size works in FileCarpenter

Split a PDF into contiguous page groups sized around a chosen maximum in MB, useful when a portal rejects large uploads and page order must stay intact.

The focused PDF Tools workspace is designed for a single job at a time. It does not require an account and does not add a FileCarpenter watermark to the downloaded result.
