Turn JPG photos into AVIF files that are often about half the size at the same visual quality - for the widest support make a WebP copy too.

AVIF often stores a photo in about half the bytes of a JPG at the same look, which helps page speed and Core Web Vitals.
Every modern browser shows AVIF - Chrome, Edge, Firefox and Safari 16.4 and later.

Need a JPG back for an old app? Use AVIF to JPG.
Drop your JPG files into the box, keep quality 65 or pick a preset, and press Convert to AVIF. More than two files come as a ZIP.
Usually 40-60% smaller at the same visual quality. Photos with smooth skies and skin tones save the most.

55-70 for websites, 80 or more when detail matters. The size shown after converting is measured from the real file.
AVIF is lossy like JPG, but it hides its losses better. At quality 65 most people cannot tell the two apart.
All modern browsers show it. Some older apps and Windows 10 without the AV1 extension do not - keep the JPG or a WebP as a fallback.
Yes. Photos taken sideways are turned upright before converting.
