What’s the difference between crop and fit?

“Crop to fill” scales the image to cover the whole frame and trims the overflow (no bars). “Fit & pad” keeps the entire image and fills the gaps — either with a solid color you pick, or with a blurred copy of the photo (the popular “blur fit” look) so nothing is cropped.

What are the safe zones on vertical sizes?

On Story, Reel, and TikTok sizes (9:16), the app’s own interface — caption, action buttons, and profile — covers parts of the frame. The shaded overlay marks roughly where that happens so you keep important content (text, faces, logos) out of those areas. It’s a preview guide only and isn’t baked into the export.

Which size should I use for the feed?

Portrait 4:5 (1080×1350) is the default because vertical formats now take up more screen and tend to out-perform square posts on most mobile-first networks. Square (1080×1080) is still fine, and Story/Reel/TikTok use 9:16 (1080×1920).

Does resizing reduce quality?

Output is rendered at full target resolution with high-quality smoothing and saved as lossless PNG, so quality stays high. Enlarging a small source past its native size will still soften it.
