# Compress PDF — Documentation & FAQ

Documentation for [Compress PDF](https://www.razi.pro/tools/pdf-compress) — Reduce the file size of your PDF documents while maintaining quality.

## Quick start

Upload a PDF and the tool will optimize images and strip metadata to reduce file size while keeping quality.

## Tips

- Image-heavy PDFs see the biggest size reductions (50-80%).
- Text-only PDFs are already compact — expect 10-30% reduction.

## Frequently asked questions

### How do I compress a PDF without losing quality?

Upload your PDF and our tool will optimize it by compressing embedded images and removing unnecessary metadata while preserving text clarity and layout. The result is a smaller file that looks virtually identical to the original.

### How much can I reduce my PDF file size?

Compression results vary depending on the PDF content. Image-heavy PDFs can often be reduced by 50-80%. Text-only PDFs are already compact and may see smaller reductions of 10-30%.

### Is the compressed PDF still printable?

Yes. The compressed PDF retains full print quality. Text, vectors, and images are optimized without degrading to a level that would affect printing.

### Can I compress multiple PDFs at once?

Currently, you can compress one PDF at a time. For batch compression, simply process each file individually — each one takes just a few seconds.
