Twitch thumbnails keep saving as AVIF and my editing software freaks out. reaConverter swaps them to JPEG instantly. Now I can actually post my ‘🔥HOT TAKES🔥’ without crying over file errors.

Google Photos auto-saved my pics as AVIF files that won’t open anywhere. reaConverter rescued 3 years of memories AND kept the quality. Take that, ‘innovation’!
