Batch Compress
Select multiple PDF files and compress them all in a single run — each one processed locally in your browser with the same quality settings applied across the batch.
Files are processed locally in your browser — no upload is required for this tool.
Frequently asked questions
How many PDFs can I compress at once in batch mode?
The number depends on your device memory and the size of the files. Typical batches of 10-20 moderately sized PDFs work smoothly; very large files may need to be done individually.
Is batch compression a paid feature?
Yes. Batch processing is available on the Pro plan. Single-file compression is free.
Are the compressed files uploaded anywhere?
No. Every file is compressed locally in your browser. Nothing is sent to a server.
Can I set different quality levels per file in a batch?
The batch applies a single quality setting across all files. For per-file control, use the single-file Compress PDF tool.
Is it safe? Are my files uploaded?
These tools run locally in your browser — for supported local operations your files are not uploaded to a server. Processing the document on your own device avoids sending it to a third party.
