Why use this tool?
Split a long PDF into regular batches or files that meet a target size. Page-count mode is deterministic; size mode measures the generated PDFs to build the groups.
Smart processing
Process PDF documents easily with operations suited to their structure.
Supported formats
Imported PDF files and downloadable results depending on the selected operation.
Save time
Get a clean, ready-to-use result in seconds without installing software or configuring a complex workflow.
Fonctionnement
How does this tool work?
In page mode, the engine successively extracts groups containing no more than the requested number of pages. In size mode, for each part it searches for the largest contiguous group whose generated PDF remains under the requested limit. A single page may exceed the target if it cannot be split further.
Use cases
Meet an upload limit
Split a large PDF before uploading it to a service with a size limit.
Create regular batches
Automatically produce files of 10, 20 or 50 pages.
Prepare batch processing
Process each part afterwards in a PDF pipeline.

Frequently asked questions
