Frequently Asked Questions

How does PDF compression work?

Our tool renders each PDF page as an image at controlled quality levels, then rebuilds the PDF. This reduces embedded fonts, vectors, and metadata overhead.

What compression levels are available?

Three levels: Low (best quality, slight reduction), Medium (balanced), and High (maximum compression, some quality loss).

What if compression makes the file larger?

Some PDFs are already optimized. If the compressed version is larger, the tool returns the original file unchanged.

Is my PDF data uploaded to a server?

No. Everything happens in your browser using pdf.js for reading and pdf-lib for writing. Your files never leave your device.
