FAQ
Which fit should I use?
Blur fill keeps the whole frame visible and looks intentional; crop fills the canvas edge-to-edge but cuts content; pad keeps everything with black bars.
What resolution is the output?
720×1280 for 9:16, 1080×1080 for 1:1, 1280×720 for 16:9 — all standard platform-native sizes.
Is this enough for Reels and TikTok?
Yes — 9:16 at 720×1280 is fully accepted by both, and the blur fill avoids the cropped-foreheads look.
