## What compression does to ODT

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 ODT

1. **Add your ODT files.** Drag and drop ODT 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 ODT, or everything at once as a ZIP.

## Good to know

- ODT files from LibreOffice and other OpenDocument editors keep their images in a Pictures folder inside the ZIP. Those are shrunk and the rest is repacked at maximum compression.
- The result is still an ODT that opens in LibreOffice, Google Docs and Word.
- Need to meet an upload limit? Set a target size (or a percentage to reduce by) in the compressor and the document is compressed to fit.
- ODT files are compressed in an isolated cloud sandbox created just for your job; the upload and the result are deleted automatically afterwards.

## Compressing ODT: frequently asked questions

### How do I compress an ODT file?

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

### Does compressing ODT reduce quality?

A little, by design: ODT 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 ODT get?

Documents with photos often shrink by more than half; text-only documents change little.

### Can I compress ODT 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 ODT 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 ODT compressor free?

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