Free bulk PDF compression

Batch compress PDF files online

Queue multiple PDFs, process them locally in one run and download the completed files as a ZIP archive. Batch PDF compression is currently included in Free while paid checkout is unavailable.

Open free batch compression

The PDFs stay on your device and are never uploaded to FitPDF.

Compress many PDFs in one browser run

Select a queue of PDF files within the device's reported capacity.
Choose the maximum size for each PDF.
Start the batch and review the status of every file.
Download all completed results in one ZIP archive.

Each PDF is analyzed and processed independently. A document that is already efficient can be included unchanged, while a skipped file gets its own explanation instead of stopping the whole batch.

Batch means PDF compression only

FitPDF does not advertise batch merging, page organizing, content placement, signing or redaction. Those tools use one active workspace at a time. Batch PDF compression is free during the pre-checkout launch period.
