Frequently Asked Questions

What's the difference between compression levels?

Low compression maintains highest quality with minimal size reduction (~10-20%). Medium provides balanced quality and size reduction (~30-50%). High compression maximizes size reduction (~50-70%) with good quality.

Will compression affect text readability?

No, text content remains perfectly readable at all compression levels. Our compression primarily targets images and redundant data while preserving text clarity.

Can I compress password-protected PDFs?

Password-protected PDFs need to be unlocked before compression. Use our PDF unlock tool first, then compress the unlocked file.

What's the maximum file size I can compress?

You can compress PDF files up to 50MB. For larger files, try splitting them first or using a different compression tool for enterprise needs.

How much can I reduce file size?

Compression effectiveness depends on content type. Image-heavy PDFs see better reduction (50-80%) while text-only documents may see modest improvements (10-30%).

Is my data safe during compression?

Yes! All processing happens locally in your browser. Your files are never uploaded to our servers, ensuring complete privacy and security.
