Technical Questions

Q

Does compressing PDF reduce quality?

A

Our advanced compression algorithm is designed to maintain document quality while reducing file size. We offer multiple compression levels so you can choose the best balance between size and quality for your specific needs.

Q

What is the maximum file size I can compress?

A

There is no strict file size limit for our PDF compressor. However, very large files (over 500MB) may take longer to process and could face browser limitations. For best performance, we recommend files under 100MB.

Q

How much can I reduce my PDF file size?

A

Compression results vary depending on your PDF content. Text-heavy documents can be reduced by 60-80%, while image-rich PDFs typically see 40-60% size reduction. Our tool automatically optimizes based on content type.

Security & Privacy

Q

Are my files safe and secure?

A

Absolutely. All PDF compression happens locally in your browser. Your files never leave your device and are never uploaded to our servers, ensuring complete privacy and security of your documents.

Q

What happens to my files after compression?

A

Since processing happens entirely in your browser, your original and compressed files remain only on your device. No files are stored on our servers, and you have complete control over your documents.

Performance & Speed

Q

How fast is the compression process?

A

Most PDF files are compressed within 5-30 seconds, depending on file size and complexity. The process runs entirely in your browser using modern web technologies for optimal performance.

Q

Can I compress multiple PDF files at once?

A

Currently, our tool processes one PDF file at a time to ensure optimal quality and performance. You can quickly compress multiple files by repeating the process for each document.
