Free online image format converter
Image formats have different advantages. PNG offers lossless compression and transparency. JPG uses lossy compression for smaller files. WebP offers better compression than both. BMP is uncompressed. GIF supports animations. Our tool converts between all these formats directly in your browser.
BMP is mainly used in Windows applications. GIF supports animations with a 256-color palette. Our tool uses the HTML5 Canvas API, without uploading files to any server.
Local processing ensures instant speed and total privacy. There are no file size limits or watermarks. For lossy formats like JPG and WebP, you can adjust the quality level.
Frequently asked questions
Is quality lost when converting between formats?
It depends on the target format. Converting to PNG or BMP does not lose quality. Converting to JPG or WebP may slightly reduce quality due to lossy compression, but you can control this with the quality slider.
What format should I use for my website?
WebP is the best format for web: it offers files up to 30% smaller than JPG with the same quality. If you need maximum compatibility with older browsers, use JPG for photos and PNG for graphics with transparency.
Are my images uploaded to any server?
No. The conversion is performed entirely in your browser using the HTML5 Canvas API. Your images never leave your device, ensuring total privacy and security.
Can I convert images with transparency?
Yes, but keep in mind that JPG and BMP do not support transparency. When converting to these formats, transparent areas will be filled with a white background. To keep transparency, use PNG or WebP.
