FAQ

Input: any browser-supported image. Output: PNG, JPEG, WebP (most reliable). GIF, BMP, AVIF, ICO, TIFF depend on browser support.
Not all browsers support these formats for canvas export. Chrome supports WebP and AVIF. Safari supports WebP. PNG and JPEG work everywhere.
PNG and WebP preserve transparency. JPEG fills transparent areas with white. Need to embed the result as Base64 in your code? Use the Image to Base64 tool.
