## How to use

1. Drag'n'drop PNG or JPEG files or directories onto main table view in ImageOptim's window.
2. Wait until it finishes.

You can also drop files onto ImageOptim's Dock icon.

## Icons in file table

| Image has been optimized successfully.
| Everything went fine, but image couldn't be optimized any further.
| Optimisation of this file is in progress.
| File is queued to be optimized after other files are finished.
| There was an error during optimisation. You'll find explanation by running Console.app.

## How does it work

ImageOptim is a front-end (GUI) for these applications:

- OptiPNG
- PNGCrush
- AdvPNG
- JpegOptim
- JpegTran
- and optionally PNGOUT.

ImageOptim runs them and automatically selects smallest file.
