Differences between JPEG, PNG and WebP
JPEG uses lossy compression and doesn't support transparency — it's the usual pick for photographs, where small losses aren't noticeable and the file gets much smaller. PNG uses lossless compression and supports transparency, making it better for screenshots, logos and images with few colors. WebP aims to combine both advantages: files are generally smaller than equivalent JPEG/PNG, with transparency support, though with somewhat newer compatibility.
What happens to transparency when converting to JPEG?
JPEG has no transparency channel. Converting an image with transparent areas to JPEG fills those areas with a background color — white by default — instead of silently dropping that information.
Quality and file size
For JPEG and WebP, a quality control sets the balance between file size and visual fidelity. Very low values produce small files with visible artifacts; very high values barely reduce the size. PNG has no such control because its compression is lossless.
When should you use this tool?
Websites and online stores
Convert photos to WebP to reduce page load times.
Email and WhatsApp
Shrink large camera photos before sending them.
Compatibility
Convert a WebP to JPEG/PNG when an older system doesn't accept the format.

Export screenshots as PNG to keep text crisp.
Privacy and processing
Conversion happens entirely in your browser using the Canvas API — the image is never sent to a server.
Frequently asked questions
- Why aren't AVIF or HEIC supported?
- Browser support for writing those formats from a canvas is inconsistent, so this tool sticks to JPEG, PNG and WebP for reliability.
