## Need a specific size?

Set a target size or a percentage to reduce by, and each file is compressed to land at or just under it.

## How to compress documents

1. **Add your documents.** Drop documents onto the compressor. You can mix PDF, DOCX or PPTX in one batch.
2. **Choose a level or a target.** Balanced suits most files. Pick Light or Strong, or set a target size or a percentage to reduce by.
3. **Compress.** Click Compress. Each file stays in its own format and comes back smaller.
4. **Download.** Download files one by one, or everything at once as a ZIP.

## Good to know

- Documents get big because of images: scans, photos and screenshots. Those are recompressed; text, fonts and layout stay intact.
- Set a target size for an upload form or an email, or a percentage to reduce by. The more of a document is images, the further it can shrink.
- Documents are compressed in an isolated cloud sandbox created for your job; uploads and results are deleted automatically.
