WebP delivers the same visual quality as JPEG and PNG at noticeably smaller file sizes, making it the format of choice for fast, modern websites. Our free WebP converter online works in both directions: convert PNG, JPG, GIF, and BMP images to WebP, or turn existing WebP files back into PNG or JPG.
Switch modes with a single tab to use it as a png to webp free tool for lighter graphics, a jpg to webp tool for smaller photos, or a WebP-to-PNG/JPG converter when you need broader compatibility with older software. A quality slider lets you dial in lossy compression, a max-quality option keeps maximum detail (and transparency) when encoding WebP, and converting to JPG offers a background color picker to flatten transparent areas. A side-by-side preview reports both file sizes and the exact percentage saved.
All conversions run entirely in your browser, so your images are processed on your device and never uploaded. Combine the WebP converter with our JPEG Converter for classic compatibility, the PNG to JPG Converter for another quick format switch, or the Image Compressor to squeeze files even smaller before publishing.
