How to use it
Choose a supported source
This page accepts common image files. A browser must be able to decode the file before it can be converted.
Choose an output type
PNG can retain transparent pixels; JPEG cannot and uses the chosen background color. WebP may use lossy or lossless encoding depending on the browser encoder.
Review and download
The output may be larger than the source. Check the preview and file size instead of assuming a conversion is automatically an optimization.
