Frequently Asked Questions

How much can I compress my PDF?

Typically 40-80% for PDFs with images. Text-only PDFs may see 10-30% reduction since text is already compact.

Will compression reduce the quality of my PDF?

Maximum compression reduces image DPI to ~150 which is good for screen viewing. Balanced mode (~300 DPI) keeps print quality. Minimum mode barely affects quality.

Is my file uploaded to a server?

Yes, for optimal compression we use server-side Ghostscript processing. Your file is automatically deleted immediately after compression. If you prefer local-only processing, the tool falls back to client-side if the server is unavailable.

What's the maximum file size I can compress?

There's no hard limit. Files up to 100MB work well. Very large files may take longer to process.
