WEBP
Raster Web Image File Format
WebP is a modern raster image format developed by Google that supports both lossy and lossless compression. It delivers smaller file sizes than JPEG or PNG while maintaining comparable visual quality, speeding up web page loads. WebP also supports transparency (alpha channel) and animation, making it a versatile choice for websites and applications seeking efficient image delivery.

FAQ
Questions & Answers
-
How long does it take to resize a WEBP image?Resizing a WEBP image takes just a second or two in most cases, since everything runs locally in your browser's JavaScript engine rather than being sent to a server. Larger files or a full batch of images may take a little longer, but you'll see progress update live as each one finishes.
-
Is it safe to resize my photos here?Yes. Your images are processed entirely on your own device using your browser's built-in canvas and Web Worker features, and they are never uploaded to a server or stored anywhere online. Once you close or refresh the page, nothing about your photos remains on our side.
-
What browser should I use?Any modern browser works well, including Chrome, Firefox, Edge, and Safari on both desktop and mobile devices. The tool relies only on standard, widely supported browser features, so there is nothing extra to install, enable, or configure.
-
Can I make a WEBP image bigger than its original size?The tool is designed to shrink images, not enlarge them - if you request a size larger than the original, it keeps the source size instead of stretching it. This avoids the blurry, pixelated look that comes from enlarging a small image.
-
What is the difference between scaling by percentage and resizing by pixels?Scaling by percentage shrinks each image in your batch relative to its own size, so a large photo and a small icon both shrink by the same proportion. Resizing by exact pixels applies the same target width and height to every image, fitting it inside that box or cropping to fill it, depending on whether you keep the original proportions.
