Best for
Not ideal for
Very large files
Large files take longer and can hit browser memory limits — try a smaller sample first.
Skipping the output check
Compare the first rows or pages of the output with the input before using it in production.
Files from unusual exporters
Some files use format variants that do not convert cleanly — if the output looks wrong, re-save the file from the app that created it and try again.
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.
quality: 75, speed: 4Outcome
The image size is reduced by over 60% while remaining visually indistinguishable from the original.
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.
AVIF offers significantly better compression ratios than PNG, resulting in much smaller file sizes without sacrificing image quality.
Yes, you can set the quality parameter between 0 and 100 to find the perfect balance for your specific needs.
The encoding speed (0-9) allows you to trade off between processing time and compression efficiency; lower values are generally faster.
Yes, the tool supports individual PNG files up to 10MB.
Most modern web browsers support AVIF, though it is always recommended to check compatibility if you are targeting legacy systems.
