How Image to WebP works
Files are validated, decoded, resized when requested, and encoded by your browser. The application does not send image files to a server, and animated inputs are rejected instead of silently losing frames.
Convert a mixed batch of images to WebP
Use this converter when you have different source formats and want WebP output for all of them. It accepts JPG/JPEG, PNG, WebP, AVIF, static GIF and standard BMP. Conversion happens on your device and does not require an account.
A change of format does not guarantee a smaller file. An efficient AVIF or a simple PNG can already be compact. Compare the final size and quality; keep your source when the conversion is not useful. Animated images are rejected instead of silently losing frames.
