# Free Compression Tools

Smart lossy and lossless file compressors for PDFs, JPEG, PNG, WEBP, MP4, and MP3 files with 100% privacy.

## What is Compression Tools?

The Compression Tools shrink files so they fit upload limits, load faster on websites and take less space. Compress a JPG, PNG or WEBP image with a quality control, compress many images at once and download them as a ZIP, reduce video size with an adjustable quality level, and re-encode MP3 files at a lower bitrate. Each tool shows the original and new size so you can balance size against quality. All compression runs on your device.

## How to use Compression Tools

1. **Pick the file type** — Image, bulk images, video or MP3.
2. **Choose the level** — Set quality, bitrate or compression strength.
3. **Compare and download** — Check the new size and download the smaller file.

## Frequently asked questions

### What is the difference between lossy and lossless compression?

Lossless compression keeps every pixel or sample and only reorganises the data. Lossy compression removes detail that is hard to notice, which saves far more space.

### Why did my file barely get smaller?

Files that are already heavily compressed — small JPGs, streaming-quality MP4s or low-bitrate MP3s — have little left to remove without visible or audible loss.

### Can I compress a PDF?

Not yet. PDF compression is not available; for scanned PDFs, splitting large documents can help meet upload limits.
