How to use the Image Converter
- Add images.
- Choose the output format and quality.
- Download each converted file.
How it works
Images are decoded to a canvas and re-encoded in the chosen format. JPG and WebP use the quality slider; PNG is lossless. Transparency becomes white in JPG.
Worked example
A 2 MB PNG photo often becomes 300–500 KB as a 85% JPG.
Good to know

WebP support depends on the browser.
