Social Media Image Size Checker and Exporter

★ 7.0 · design

social-media-image-sizes is a Claude Code skill that checks image dimensions and exports correctly sized copies for 9 platforms — Instagram, Facebook, X (Twitter), LinkedIn, TikTok, YouTube, Pinterest, Snapchat, and Threads — covering 60+ specs. scripts/check.js produces a ranked match list (perfect → close → usable → too small) with inline resize commands, filterable by platform slug or match level. scripts/resize.js exports a resized copy using cover (center-crop) or contain (letterbox) fit, with optional background color and custom output path. Built on Node.js 18+ and Sharp, the skill also ships per-platform reference files detailing safe zones, carousel rules, and ad formats. It's the practical choice for validating image dimensions, prepping social media assets, or resizing creatives for ad campaigns.
