Image Utility
Image Format Converter
Convert PNG, JPEG, or WebP images to PNG, JPEG, or WebP locally in the browser.
Method
The selected image is decoded by the browser, drawn to a canvas, and encoded into the requested output MIME type. JPEG/WebP expose a quality setting. Transparent pixels are placed on white for JPEG because JPEG has no alpha channel.
Worked example
A transparent PNG can be converted to WebP while preserving transparency, or to JPEG with a white background.
