Enter a website URL to analyze images and optimize them to WebP format, or choose between WebP and WebM formats for animated images (GIF, APNG, WebP) for better performance.

Step 1: Enter Website URL

About WebP and WebM Formats

WebP is a modern image format developed by Google that provides superior compression for both lossy and lossless images compared to JPEG and PNG. WebP images often achieve about 25-34% smaller file sizes than JPEG at comparable quality.

Key features of WebP include:

  • Support for both lossy and lossless compression.
  • Alpha transparency support (like PNG).
  • Animated WebP support, allowing smaller and higher quality animations than GIFs.
  • Broad modern browser support (Chrome, Firefox, Edge, Safari).
  • Efficient decoding and smaller file sizes improve web page load times and save bandwidth.

WebM is an open-source video format also developed by Google, primarily for efficient video and audio streaming on the web. It is used for encoding videos with VP8/VP9 codecs designed for low CPU requirements and small file sizes.

While WebM is not typically used for still images, it can be used for video-based animations or interactive media that require higher compression efficiency than traditional animated GIFs or WebP animations.

Why Use WebP and WebM for Your Website?

  • Faster Loading: Smaller file sizes mean pages load faster, improving user experience and SEO.
  • Better Quality: WebP preserves image quality better than older formats at similar sizes.
  • Bandwidth Savings: Reducing image weight reduces data consumption, important for mobile users.
  • Animation Support: Animated WebP offers richer animations with smaller size compared to GIF.
  • Free and Open: Both are open-source formats with no licensing fees.

Implementation Tips

To support all users, include fallback options for browsers that do not support WebP or WebM by using the <picture> element for images and <video> element for videos, specifying alternative formats such as JPEG, PNG, or MP4.

Example for images:


<picture>
  <source srcset="image.webp" type="image/webp">
  <img src="image.jpg" alt="Description">
</picture>

Example for videos:


<video controls>
  <source src="video.webm" type="video/webm">
  <source src="video.mp4" type="video/mp4">
  Your browser does not support the video tag.
</video>

By integrating image scraping and conversion tools that generate WebP/WebM versions of your media, your website can serve optimized content seamlessly.
