Convert Image Format
Convert images between JPG, PNG and WebP directly in your browser. Fast, private, watermark-free format conversion.
Runs entirely in your browser — no uploadsAbout this tool
Convert Image Format transcodes any browser-supported bitmap — including GIF and BMP inputs — to JPG, PNG or WebP with adjustable quality.
Converting to JPG flattens transparency onto a white background, since JPEG cannot store alpha. PNG and WebP preserve transparency. Conversion happens entirely through your browser’s canvas engine.
FAQ
Why does PNG turn white where it was transparent?
JPEG doesn’t support transparency, so transparent areas are flattened onto white. Choose PNG or WebP output to keep transparency.
Which format is smallest?
WebP usually wins for both photos and graphics at similar visual quality, followed by JPG, then PNG.
Can I convert animated GIFs?
Only the first frame is converted — animated output formats aren’t supported in-browser.
