LaunchKit
Chrome extension asset studio — icons, screenshots, and promo images in one place
Generate, edit, and manage all the image assets you need to publish on the Chrome Web Store. Upload one icon to get all 4 required sizes, design screenshots and promo tiles with a built-in canvas editor, and export everything as a ZIP. Runs entirely in your browser — no backend, no uploads, no accounts.
Features
Everything you need, built right in.

Upload a single icon and automatically generate all 4 Chrome Web Store sizes (16, 32, 48, 128px) in one click.
Visual Canvas Editor
Full-featured editor with text, shapes, images, drag-and-drop, resize, rotate, undo/redo, and keyboard shortcuts — built on Konva.
Screenshot Builder
Create pixel-perfect screenshots at the exact CWS dimensions (1280x800 or 640x400) with a visual editor and re-editable canvas JSON.
Promo Image Creator
Design all three promo tile sizes — Small (440x280), Large (920x680), and Marquee (1400x560) — from one unified editor.
ZIP Export
Download all your assets organized by type in a single ZIP file. Icons, screenshots, and promo images neatly folder-structured.
100% Browser-Based
Everything runs locally with SQLite WASM + OPFS. No server uploads, no accounts, no data leaves your machine.
