How do I convert bitmap files between PNG, JPEG, and WebP?

Upload a bitmap file, choose the target format, adjust quality and max dimension if needed, then download the converted output from the browser.

Use this route when the main goal is changing the output format rather than only shrinking size.
JPEG export automatically uses a white background fallback when the target format does not support transparency.
The result panel shows output size so you can compare the converted file against the original asset.

How to convert a bitmap image

1.Select a PNG, JPEG, WebP, BMP, GIF, or AVIF source file.
2.Pick PNG, JPEG, or WebP as the target format and tune quality or max dimension if needed.
3.Run the conversion, review the output size, and download the converted file.

FAQ

When should I use bitmap convert instead of bitmap compress?

Use bitmap convert when the output format must change, such as PNG to WebP or JPEG to PNG. Use bitmap compress when you mainly want a smaller file.

What happens to transparent areas when I export JPEG?

JPEG does not support transparency, so the converter applies a white background when JPEG is selected as the output format.

Can I still reduce size while converting format?

Yes. Quality and max-dimension controls let you reduce the final file size while also changing the output format.
