Examples
1. Optimizing Hero Images for Web Performance
Web Developer
Background
A high-resolution hero image in AVIF format was causing slow page loads on mobile devices.
Problem
The original file was too large, negatively impacting the site's performance score.
How to use
Upload the image, set quality to 75, and enable 'Clear All Metadata' to strip unnecessary data.
quality: 75, clearMetadata: true
Outcome
The image file size was reduced by 40% while maintaining visual clarity, significantly improving page load speed.
2. Preparing Assets for Mobile-First Design
UI/UX Designer
Background
A collection of UI icons and graphics in AVIF format needed to be as lightweight as possible for a mobile app.

How to use
Use the 'Max Compression' chroma subsampling setting and set the effort level to 9 for the best possible reduction.
FAQ
What is the benefit of optimizing AVIF files?
Optimizing AVIF files reduces their file size, which leads to faster page load speeds, better user experience, and improved Core Web Vitals scores.
Can I keep my image's transparency?
Yes, the tool includes a 'Preserve Transparency' option that ensures the alpha channel is maintained during the optimization process.
Does removing metadata affect image quality?
No, removing metadata like EXIF data only strips non-visual information, reducing file size without impacting the actual image pixels.
What does the 'Effort Level' setting do?
The effort level determines how much time the encoder spends searching for the best compression. Higher levels result in smaller files but take longer to process.
Can I set a specific target file size?
Yes, you can input a target size in KB, and the tool will attempt to optimize the image to meet that requirement.
