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.
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.
Frequently asked questions
Is batch compression free on the web?
Yes. Batch compression is free in the CyvoDocOps web app and needs no account.
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.
