Frequently Asked Questions

Find Quick Answers

Is PDF compression safe?

Yes, your files are processed securely and deleted from our servers immediately after compression. We don't store or share your documents.

What compression levels are available?

Three levels: Low (minimal size reduction, highest quality), Medium (balanced reduction and quality), and High (maximum size reduction, some quality loss).

Is there a file size limit?

The tool can handle PDF files up to 50MB in size. For larger files, consider splitting them first.

Does compression affect PDF quality?

Higher compression levels may reduce image quality slightly. For text-heavy documents, quality loss is minimal even at high compression.
