## What compression does to ODP

Shrinks the embedded photos and repacks the document at maximum compression; text and layout are untouched.

- **Light:** Gentle: images are recompressed but stay close to the original; good for print.
- **Balanced (default):** The default: images are optimised for reading on screen, usually with no visible difference.
- **Strong:** Smallest file: images are downsampled further; fine on screen, not for print.

## How to compress ODP

1. **Add your ODP files.** Drag and drop ODP files onto the compressor, paste them, or click to browse. You can add several at once.
2. **Pick a level or a target.** Balanced is selected and suits most files. Choose Light to stay closer to the original or Strong for the smallest file, or set a target size or a percentage to reduce by.
3. **Compress.** Click Compress. Files are processed in an isolated cloud sandbox and are usually ready in seconds.
4. **Download.** Download each smaller ODP, or everything at once as a ZIP.

## Good to know

- LibreOffice Impress decks store slide images inside the ODP's ZIP container. Those are shrunk; slides and transitions are left alone.
- The result is still an ODP that opens in LibreOffice Impress, Google Slides and PowerPoint.
- Need to meet an upload limit? Set a target size (or a percentage to reduce by) in the compressor and the presentation is compressed to fit.
- ODP files are compressed in an isolated cloud sandbox created just for your job; the upload and the result are deleted automatically afterwards.

## Compressing ODP: frequently asked questions

### How do I compress an ODP file?

Drop the ODP onto the compressor above, keep Balanced or pick another level, and click Compress. Download the smaller ODP when it's done; it usually takes a few seconds.

### Does compressing ODP reduce quality?

A little, by design: ODP is a lossy format. Balanced is tuned to look the same for most uses; choose Light if you want to stay closer to the original.

### How much smaller will my ODP get?

Photo-heavy decks often shrink by more than half; text-only decks change little.

### Can I compress ODP to a specific size?

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

### Is it safe to compress ODP files here?

Yes. Your file travels over an encrypted connection to an isolated sandbox created for your job only, and both the original and the result are deleted automatically.

### Is the ODP compressor free?

Yes. Cloud jobs like this one use the same free daily credits as cloud conversions, and there's no watermark.
