About Image Converter
Different image formats suit different jobs. PNG is lossless and supports transparency, JPEG gives small files for photographs, and WebP often produces smaller files than both at similar quality.
This tool converts images between PNG, JPEG, and WebP and can resize them, using the browser's Canvas API. The image is processed on your device and never uploaded. For JPEG and WebP you can trade quality for file size; lossy formats lose some detail each time they are re-encoded, so keep an original.
Common use cases
- Converting a PNG screenshot to a smaller WebP for a website.
- Resizing an image to fit an upload size limit.
- Turning a WebP image into JPEG or PNG for software that does not support it.
- Reducing the file size of a photograph.
Frequently asked questions
- Which format should I use for the web?
- WebP is a good default for modern browsers. Use PNG when you need lossless quality or transparency, and JPEG for compatibility.
- Does converting to JPEG remove transparency?
- Yes. JPEG has no transparency, so transparent areas are filled with a solid background.
- Are my images uploaded?
- No. Conversion happens in your browser using the Canvas API.
