File format & quality tips
- Pixel size first. Match the dimensions above exactly — uploading larger and letting YouTube downscale is fine; uploading smaller makes it blurry.
- PNG for logos, icons and avatars (crisp edges, supports transparency). JPG / WebP for photos and detailed banners (smaller files, faster loads).
- Mind the safe zone. Wide banners get cropped differently on phone vs desktop — keep text and faces centered.
- Export once, right. AI All Social outputs the exact YouTube size in PNG, JPG or WebP, safe-zone aware, so you skip the resize dance.
YouTube sizes — FAQ
What is the best YouTube channel icon size?
800 x 800 px (1:1). Upload at that exact size so YouTube doesn't crop or compress it.
What file format should I use for YouTube?
PNG for logos, avatars and anything with sharp edges or transparency; JPG or WebP for photos and busy banners to keep the file smaller. AI All Social can export PNG, JPG or WebP.
Why does my YouTube image look cropped or blurry?
It was the wrong size or aspect ratio, so YouTube cropped or compressed it. Upload at the recommended pixel size and keep the subject inside the safe zone.
Can I make YouTube images without design skills?
Yes — describe what you want, pick the YouTube surface, and AI All Social generates it at the exact size, safe-zone cropped and upload-ready.
