WebP to AVIF Converter

Summary

Drop a WebP image, adjust quality, and download it as AVIF — all processed locally in your browser.

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.
