Summary

This tool converts WebP images to AVIF format entirely inside your browser using the Canvas API — nothing is ever uploaded to a server. AVIF typically achieves 20–50% smaller file sizes than WebP at equivalent visual quality, making it the modern choice for web performance. Adjust the quality slider, preview the result, and download the converted file in seconds.

How it works

  1. Select or drag a WebP image onto the drop zone.
  2. The image is decoded in the browser using an HTML Canvas element.
  3. Adjust the quality slider (1–100) to balance size vs. quality.
  4. Click Convert to encode the canvas output as an AVIF blob.
  5. Compare the original and converted file sizes, then download the AVIF file.

Use cases

  • Reduce image payload on websites by switching from WebP to AVIF.
  • Batch-test different quality levels before choosing a compression setting.
  • Convert design exports to AVIF without installing desktop software.
  • Verify AVIF compatibility and file size before updating a CDN pipeline.
  • Quickly produce AVIF assets for blog posts and landing pages.
  • Check how much space you save compared to your original WebP file.
