Examples

1. Optimizing Website Hero Images

Web Developer

Background

A developer needs to replace heavy WebP hero images with AVIF to improve page load times on a high-traffic landing page.

Problem

The current WebP files are still too large, causing slow LCP (Largest Contentful Paint) metrics.

How to use

Upload the WebP hero image, set quality to 60, and use a compression effort of 6 for a balance of speed and size.

quality: 60, effort: 6, lossless: false

Outcome

The image file size is reduced by an additional 30% without visible quality loss, significantly improving page load performance.

2. Archiving High-Quality Graphics

Graphic Designer

Background

A designer wants to archive a collection of WebP assets into a more future-proof and efficient format.

Problem

Need to ensure zero quality degradation during the format migration.

How to use

Upload the WebP file and enable the 'Lossless Compression' option.

FAQ

What is the main advantage of AVIF over WebP?

AVIF typically offers better compression efficiency, resulting in smaller file sizes than WebP while maintaining the same or better visual quality.

Can I perform lossless conversion?

Yes, you can enable the 'Lossless Compression' checkbox to ensure the image data remains identical to the original.

What does the 'Compression Effort' setting do?

It controls the balance between encoding speed and file size; higher values result in better compression but take longer to process.

Is there a limit to the file size I can upload?

Yes, the tool supports individual files up to 10MB.

Will I lose image quality during conversion?

If you use lossy compression, some data is discarded to save space. You can adjust the quality slider to find the perfect balance for your needs.
