How to use it
- Choose a file and a target format: WebP for the web, JPEG for photos, PNG for lossless.
- Quality applies to WebP and JPEG; PNG is always lossless.
- When converting to JPEG, pick a background color for transparent areas.
- Download the converted image. Format support depends on your browser and is checked automatically.
About this tool
Re-encodes images into the formats your browser supports and reports when a requested format is unavailable. Transparency handling is explicit: JPEG output composites over a background color you choose, so PNG transparency never becomes surprise black.
Your input never leaves the browser: this tool works entirely offline once the page has loaded.
Frequently asked questions
Why is JPEG not offered for transparent images without a background color?
JPEG has no alpha channel, so transparent pixels need a background. The tool asks for one and composites it for you, avoiding surprise black areas.
What happens to animated GIFs?
Only the first frame is converted — the browser's encoder cannot write animated GIFs. Use dedicated tools for animation work.
