Compress WebP images online.

WebP is Google's modern image format that delivers 25-35% smaller files than JPEG at equivalent quality. It supports lossy and lossless compression, transparency (alpha channel), and animation — making it a versatile replacement for both JPEG and PNG.

Browser support for WebP has reached over 97% globally, making it a safe choice for production websites. Our compressor uses the libwebp encoder with full control over quality, method, and compression mode.

Key features

  • 25-35% smaller files than JPEG at same quality
  • Lossy and lossless compression modes
  • Full alpha channel transparency support
  • Animation support for animated WebP
  • Adjustable compression method (0-6) for density

How to compress webp — step by step

  1. Drop your image: Drag and drop any image format onto the upload area — JPEG, PNG, WebP, or AVIF are all accepted.
  2. Configure WebP settings: Adjust quality (1-100), choose lossy or lossless mode, and set the compression method (0-6) for optimal density.
  3. Preview the result: Use the side-by-side comparison slider to verify quality, especially around edges and gradients.
  4. Download your WebP: Save individual WebP files or download all as a ZIP. Your originals never leave your device.

Common use cases

Whether you are a photographer, web developer, e-commerce manager, or social media creator, optimizing images before publishing saves bandwidth, improves page load times, and ensures compatibility with platform-specific requirements. Our browser-based compressor works with all major image formats and processes everything locally for your browser with no uploads.

Frequently Asked Questions

  • Is WebP better than JPEG?

    WebP typically produces files 25-35% smaller than JPEG at the same quality level, with fewer artefacts in gradient areas. It also supports transparency and animation — features JPEG cannot offer.

  • Does WebP support transparency?

    Yes. WebP has full alpha channel support, similar to PNG. Our compressor preserves transparency while independently optimizing the colour and alpha planes for maximum compression.

  • What is the difference between lossy and lossless WebP?

    Lossy WebP uses block-based predictive coding similar to VP8 video compression. Lossless WebP uses spatial prediction and colour cache for excellent compression without any quality loss.

  • Can I convert JPEG to WebP?

    Yes. Drop a JPEG and set the output format to WebP. The compressor re-encodes from the source into WebP, typically saving an additional 25-35% compared to the original JPEG.

  • Is WebP supported by all browsers?

    WebP is supported by Chrome, Firefox, Safari (14+), Edge, and Opera — over 97% of global browser usage. For the remaining 3%, serve a JPEG fallback.
