WebP Converter
Convert any image to WebP with adjustable quality. Runs entirely in your browser.
WebP consistently produces smaller files than JPEG or PNG at equivalent visual quality, which is why it's become the default format modern browsers request for web images. This tool decodes any image your browser can open and re-encodes it as WebP using the browser's native encoder, with a quality slider for fine control. It's a focused, single-purpose path when WebP is always your target format; for converting between several formats in one place, use the Image Format Converter instead.

Common questions
Why WebP?
WebP files are typically 25-35% smaller than equivalent JPEG/PNG at the same visual quality - great for web performance.
Does it upload my image?
No - conversion happens locally using the browser's built-in WebP encoder.
Does WebP support transparency?
Yes - WebP supports an alpha channel, so transparent PNGs convert without losing their transparency.
Will every browser display WebP?
All major modern browsers support WebP. If you need guaranteed legacy support, keep a JPEG or PNG fallback.
