Chrome Extension Promo Tile Generator
Small (440x280), Large (920x680), and Marquee (1400x560) — generated from one image.
Publishing a Chrome extension? The Chrome Web Store requires up to 3 promotional tile images at specific dimensions (Small 440 x 280, Large 920 x 680, Marquee 1400 x 560). Extensions WITH all 3 get more visibility in featured carousels and search results; extensions with only the required small tile get less promotion.
This tool takes a single high-resolution source image (1400 wide or larger recommended) and generates all 3 tiles instantly with proper aspect-ratio handling — center-cropping where needed to match each target ratio. Everything processes in your browser; no upload, no signup, no watermark.
