# asc screenshot resize Use this skill to prepare screenshots for App Store Connect. Do not rely on a hard-coded dimension table in this skill; the CLI owns the current size matrix. ## Source of truth Always discover current accepted sizes from `asc` first: ```bash asc screenshots sizes --output table asc screenshots sizes --all --output table ``` For local validation before upload: ```bash asc screenshots validate --path "./screenshots/iphone" --device-type "IPHONE_65" --output table asc screenshots validate --path "./screenshots/ipad" --device-type "IPAD_PRO_3GEN_129" --output table ``` Common current device-type anchors: - `IPHONE_65` for the common 6.5-inch iPhone screenshot set. - `IPAD_PRO_3GEN_129` for the common 12.9/13-inch iPad screenshot set. Run `asc screenshots sizes --all` when targeting other display types such as 6.9-inch iPhone, Apple TV, Mac, Vision Pro, iMessage, or Watch. ## Workflow ### 1. Sanitize filenames macOS screenshots can contain hidden Unicode spaces that make tools fail with "not a valid file". Sanitize before batch work: ```bash python3 -c " import os for f in os.listdir('.'): clean = f.replace('\u202f', ' ') if f != clean: os.rename(f, clean) print(

Where does this skill come from?
From rorkai/app-store-connect-cli-skills, a repository with 948 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
