// AVIF CONVERTER · ABOUT THIS TOOL
About the AVIF Converter
AVIF is the biggest easy win left in web image performance: the same photo at a third to half the bytes, supported by every major browser. This converter encodes with your browser's own AVIF support, so conversion is private, instant and free.
One honest limitation: encoding needs browser support, not a server. If AVIF is unavailable, the tool tells you plainly and suggests a browser that can do it.
Where it helps most
Half the size, same picture.
Faster websites
That kind of saving compounds fast on a site with hundreds of images, cutting page load times, bandwidth bills, and mobile data use for your visitors.
Core Web Vitals
Bloggers use it to hit Core Web Vitals targets without upgrading their hosting. Converting featured images is often the single biggest win.
Photo archiving
Photographers use it to archive shots at lower bitrates. At quality 75, a 2 MB JPEG lands around 700 to 900 KB with no difference a customer could spot.
Batch conversion
Batch conversion is supported, so you can drop a whole folder of images and convert them in one go instead of repeating the process twenty times.
Getting honest savings
What the numbers really look like.
Pick your quality
Drop toward 60 for tiny thumbnails that still look clean, hold near 90 for portfolio photos where every detail matters.
Real savings
A 2 MB JPEG product photo typically lands around 700 to 900 KB at quality 75, with no visible difference.
Universal support
Google, Apple, Microsoft, and Mozilla have all backed AVIF, and it now works in every modern browser. Web developers are switching their image pipelines to it.
AVIF Converter: private by design
Your photos never leave your computer: no upload queue, no server file cap, safe for client work.
AVIF Converter FAQs
Roughly half. At the same visual quality, AVIF files are typically 40 to 50 percent smaller than JPEGs, and about 30 percent smaller than WebP. A 2 MB JPEG often becomes a 900 KB AVIF with no visible difference.
