JPG, PNG, WebP or AVIF. They never leave your device.
Compresses and converts JPG, PNG, WebP and AVIF images entirely in your browser. Converting to WebP typically saves 25-40% over JPG at the same visual quality, and resizing to the width you actually display saves far more than that.
Frequently asked
Are my images uploaded?+
No. The conversion uses a canvas in your own browser. Nothing is sent to a server, which is also why it works with no file size limit beyond your device's memory.
Which format should I pick?+
WebP for almost everything on the web. Keep PNG only when you need lossless quality or transparency that WebP would not preserve well.
