## What compression does to ODS

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 ODS

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

## Good to know

- LibreOffice Calc spreadsheets are compressed XML already, so the gains come from embedded pictures and maximum ZIP compression.
- Formulas, sheets and formatting are untouched, and the file still opens in LibreOffice, Google Sheets and Excel.
- Need to meet an upload limit? Set a target size (or a percentage to reduce by) in the compressor and the spreadsheet is compressed to fit.
- ODS files are compressed in an isolated cloud sandbox created just for your job; the upload and the result are deleted automatically afterwards.

## Compressing ODS: frequently asked questions

### How do I compress an ODS file?

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

### Does compressing ODS reduce quality?

A little, by design: ODS 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 ODS get?

Spreadsheets with pictures shrink well; data-only spreadsheets change little.

### Can I compress ODS 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 ODS 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 ODS compressor free?

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