• JPEG (progressive and baseline)

Main capabilities

• View original and optimized images side-by-side to quickly judge differences
• See live previews of changes as you tweak settings

Who benefits from it

Photographers preparing portfolios, web developers optimizing assets for faster sites, and anyone managing large image collections will find RIOT Portable useful. It’s particularly handy when you need a lightweight tool that speeds up repetitive optimization tasks without sacrificing control.

Suggested free alternative
