🟢get_image_sizes(id, platform)
Exact image sizes for Instagram, YouTube, TikTok, X, LinkedIn, Facebook, Discord, Twitch, Pinterest, marketplaces and passport photos, with safe zones (pixel areas the app covers or crops), upload limits and minimum sizes. Free, no API key. With no arguments it lists every size id; pass `id` (e.g. "youtube-banner/banner") or `platform` (e.g. "Instagram") for full details.

}⚪ai_extend_image(image_url, image_base64, ratio)
Extend an image to a wider or taller shape with AI, e.g. a portrait photo to a 16:9 YouTube thumbnail without cropping the subject. Costs 5 CropDen credits per run, refunded if it fails. Needs a CropDen API key. Input: PNG, JPEG or WebP, up to 10 MB and 2048 px on the longest side. Returns a link to the result, valid 7 days.
