Supports JPG, PNG, GIF, BMP, SVG, AVIF, ICO — converts to WebP
Files stay on your device. Nothing sent to any server.
Process hundreds of images at once with no limits.
WebP files are 25–35% smaller than JPEG or PNG.
WebP is Google's modern image format designed to make the web faster. It replaces older formats like JPEG and PNG with a single, more efficient alternative that achieves 25–35% better compression than JPEG and up to 26% better than PNG in lossless mode — all without any perceptible loss of image quality. Switching your images to WebP is one of the highest-impact optimizations you can make for web performance.
Search engines and performance tools actively reward WebP adoption. Google's PageSpeed Insights and Lighthouse audits explicitly flag images served in JPEG or PNG when WebP equivalents would be smaller, and this directly affects your Core Web Vitals scores — which in turn influence your search rankings. Serving WebP images is no longer optional for competitive web performance; it's an expected baseline.
Beyond performance scores, WebP reduces real bandwidth consumption. For high-traffic sites with many images — e-commerce catalogs, photo blogs, news sites — the cumulative savings in data transfer can translate to meaningful reductions in CDN and hosting costs. Mobile users on constrained data plans also benefit directly from smaller image payloads and faster load times.
imgToWebP converts your images entirely inside your browser. Your files never leave your device — no server uploads, no cloud processing, no privacy risk. Here's the process:
imgToWebP supports converting to and from a wide range of image formats:
The most common format for photographs. Lossy compression, no transparency. Universal compatibility across every device and application.
Lossless compression with full alpha transparency. Ideal for logos, icons, screenshots, and any image where perfect pixel accuracy matters.
Classic format with a 256-color limit and support for simple animation. Widely used for loops and memes, though limited in color accuracy.
Microsoft's uncompressed bitmap format. Large file sizes but no quality loss. Used by some Windows applications and legacy software.
XML-based vector format that scales to any resolution. Best for logos and illustrations, but can be converted to WebP for raster contexts.
The latest generation format with even better compression than WebP. Supported by all modern browsers. Ideal for high-performance sites.
Windows icon container format, primarily used for favicons. Can contain multiple sizes in one file. Convert to WebP to use icon artwork as a regular image.
Google's modern web format. The recommended choice for any image served on a website. Convert from WebP to other formats when you need broader compatibility.
WebP is a modern image format developed by Google that provides superior compression for images on the web. It supports both lossy and lossless compression.
Yes! When you upload an image, it never travels to any server — not ours, not anyone else's. Everything happens inside your own browser using your device's processing power. Think of it like using a calculator: the math happens on the device in your hand, not somewhere in the cloud.
