Traditional Challenges for Content Creators & YouTubers
Broken Social Media Preview Cards
Sharing blog and video links on Twitter/X or LinkedIn often results in ugly, cropped, or missing thumbnail cards.
Inaccessible YouTube Thumbnails

iPhone HEIC Compatibility Woes
Transferring b-roll photos from an iPhone creates incompatible HEIC files that editing software refuses to import.
