Feed Safe Images

Pads your photos onto a solid canvas at the exact ratio each feed uses, so X, Instagram, Threads, or LinkedIn shows the whole frame in the timeline instead of cropping it to a thumbnail. The source ships `scripts/pad.sh`, a thin ffmpeg wrapper with preset layouts per platform, including a 5:4 `xc` layout for multi-image X carousels and a `film` mode that adds a thin black frame with rounded corners for Instagram. The useful detail is that the author live-tested the ratios against real posts and notes that third-party size guides go stale, so trust a live preview over a guide. The `igblack` option is worth knowing if you post horizontal photos and can't afford to lose the edges to the film crop. The main thing to watch is that mixed ratios within one post get cropped unpredictably, so pad every image to the same layout.

Feed-safe images

Social feeds crop photos to a fixed ratio in the timeline. Only the full-screen view shows the whole frame, and most people never tap. The fix is to put the photo on a solid canvas at the ratio the feed will show, so the crop hits the padding instead of the photo.

This skill ships scripts/pad.sh, an ffmpeg one-liner wrapped with the right canvas per platform layout.
