Examples

1. Optimizing Web Hero Images

Web Developer
Background
A developer needs to replace heavy PNG hero images on a landing page to improve page load speed.
Problem
The original PNG files are too large, causing slow LCP (Largest Contentful Paint) metrics.
How to Use
Upload the PNG hero image and set the quality to 75 for an optimal balance of size and detail.
Example Config
quality: 75, speed: 4
Outcome
The image size is reduced by over 60% while remaining visually indistinguishable from the original.

2. Batch Asset Compression

Content Manager
Background
A content manager is preparing a set of product images for a new e-commerce storefront.
Problem
High-resolution PNGs are consuming too much bandwidth, increasing hosting costs.
How to Use
Process each product image through the converter, using a quality setting of 80 to ensure product details remain sharp.
Example Config
quality: 80, speed: 2
Outcome
The storefront loads significantly faster, providing a smoother experience for mobile users.

FAQ

What is the advantage of AVIF over PNG?

AVIF offers significantly better compression ratios than PNG, resulting in much smaller file sizes without sacrificing image quality.

Can I adjust the output quality?

Yes, you can set the quality parameter between 0 and 100 to find the perfect balance for your specific needs.

What does the encoding speed setting do?

The encoding speed (0-9) allows you to trade off between processing time and compression efficiency; lower values are generally faster.

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

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

Is AVIF supported by all browsers?

Most modern web browsers support AVIF, though it is always recommended to check compatibility if you are targeting legacy systems.
