About Image Format Converter

The Image Format Converter changes an image from one format to another, with a quality control for lossy targets and a preview before download. It is a general-purpose converter for when a specific format is required.

Different platforms and workflows demand different formats. Converting locally produces the format you need with control over quality, and the image is never uploaded.

Converting to a lossless format (PNG, BMP) preserves quality. For JPG and WebP you control quality with the slider.
