Switch a single image between formats with a quality slider — for a photo that needs to become a WebP for a website, a WebP that needs to become a plain JPG for something that doesn't accept it yet, or a screenshot that needs to stay a lossless PNG.
Upload an image, pick the output format and quality, and convert.
WebP support is broad but not universal — some older tools, some upload portals, and some legacy software still only accept JPG or PNG. Converting to JPG here usually resolves that instantly.
For JPG and WebP, it trades file size for visual fidelity — lower quality means a smaller file with more compression artifacts. PNG is always lossless regardless of the slider, so quality has no visible effect there.
See the JPG vs PNG vs WebP guide for a plain breakdown of when each one wins.
