JPEG vs AVIF: Is It Finally Time to Retire the JPG?
JPEG has served the web for decades, but the digital landscape has evolved. With mobile-first indexing and Core Web Vitals punishing slow websites, legacy formats are costing you traffic. Enter AVIF.

There is virtually no metric where JPEG beats AVIF today, other than legacy hardware encoding speed. AVIF provides massive file size reductions (up to 60%), superior color depth, transparency support, and crisp text rendering that JPEG simply cannot match.
The Problem with JPEG
JPEG uses a DCT (Discrete Cosine Transform) compression algorithm that divides an image into 8x8 pixel blocks. When compressed heavily to save bandwidth, these blocks become visible, resulting in the famous "JPEG artifacting" that makes edges look messy and text unreadable. Furthermore, JPEG does not support transparency.
The AVIF Advantage
AVIF uses the incredibly efficient AV1 video codec to compress still images. It was designed from the ground up to solve the exact problems JPEG suffers from, offering HDR support, transparency, and a drastically different compression technique that results in soft blur at extreme compression, rather than ugly blocks.
File Size Savings
Converting a 500KB JPEG to an AVIF will often result in a file that is around 200KB, with no perceivable loss in quality. This 60% reduction translates directly to faster LCP (Largest Contentful Paint) times for your users.
