## Compress PDF file size in three steps

Docs Bunny optimizes document streams, object tables, and embedded assets locally to decrease file size without cloud uploads.

## Steps

1. **Select your PDF** — Choose a PDF file from your device. It is processed locally.

3. **Download the smaller PDF** — Save the compressed PDF directly to your device.

## Common questions

### Is my PDF uploaded to a server to compress it?

No. All PDF stream packing, object compression, and optimization happen entirely in your browser.

### Will compressed text remain sharp and readable?

Yes. Object stream compression preserves vector paths and fonts with no visual quality loss.
