Frequently Asked Questions
How does PDF compression work?
PDF compression reduces file size by optimizing image quality, removing embedded fonts that aren't needed, and stripping metadata. Our tool provides lossless compression of PDF structure without degrading embedded images.
Is my PDF uploaded to a server?
No. PDF processing happens in your browser using JavaScript. Your file never leaves your device.
How much can I reduce a PDF's size?
For PDFs with large embedded images, compression can reduce size by 30–80%. For text-only PDFs, the reduction is typically 5–20%.
Will compression affect PDF quality?
The tool removes unnecessary metadata and optimizes structure without changing text or layout. Image quality is preserved with our lossless compression option.
