Summary
Image converter converts images from one format to another, such as PNG to JPG or WebP to PNG. When converting, you can set the quality of compression and you have to consider whether the target format supports transparency or animation. Conversion is not just about changing extensions: pixel data is often recycled and can change.
Key points
- Lossy formats like JPEG throw out some of the data to shrink the file
- Lossless formats such as PNG retain pixel data
- Transparency only survives on alpha-supported formats.
- Slider quality affects file size and image detail
- Conversion to a more wasteful format won't restore quality that's been lost.
