RapidPNG

Sam Bender

Simplify image downloading and conversion and save images directly as PNG! No need to go to external sites or popups, just right click on an image and choose the new "Save Image as PNG" option within the context menu. All of the conversion is done instantly upon download and in the background so it feels just as integrated as the regular Save option you are used to. This bare bones and simple extension won't run processes in the background, it only gets to work once you specifically choose to download something via the new option. Supports instant conversion/download from many formats, such as: - JPG/JPEG - WEBP - SVG - GIF - BMP and more!
