Frequently Asked Questions

Everything you need to know about PDF compression

Absolutely safe. All compression happens locally in your browser - your files never leave your computer. We don't upload anything to servers, ensuring complete privacy and security for your documents.

Compression results vary depending on your PDF content. Image-heavy documents can see 50-80% size reduction, while text-based documents typically achieve 20-50% reduction. You can choose different compression levels to balance quality and file size.

Our smart compression technology preserves text and vector graphics perfectly. Images are optimized intelligently - at higher compression levels you might notice minor quality loss in photos, but documents remain perfectly readable and professional.

No file size limits! You can compress PDFs of any size. However, very large files (100+ MB) might take longer to process depending on your device's capabilities. For best performance, we recommend files under 50MB.
