What is the Image Format Converter?

The free Image Format Converter converts images between PNG, JPEG, WebP, and AVIF entirely in your browser — no upload to any server, no account required. Drop or select your image into the drop zone, click an Output Format button (PNG, JPEG, WebP, or AVIF), and a side-by-side Original vs Converted preview appears instantly showing both the visual result and the new file size. For JPEG output a Quality slider (10–100%) lets you balance file size against image quality, and a Background colour picker fills any transparency before conversion.
