Beautiful Client Previews,
Created in One Place.
Lumist Frame converts raw screenshots and copy into gorgeous desktop, mobile, and native social ad mockups. Present your work professionally without the cloud friction.
Hardware-Accelerated Wrappers
Wrap screenshots instantly in beautiful, modern Safari-style browser windows or minimalist mobile phone mockups on elegant gradient backdrops.
Social Ad Feeds
Generate native mockups for Facebook, Instagram, LinkedIn, and Google Search campaigns. Perfect for showing clients exact, in-situ ad placements.
Offline Compilation
We process image renders entirely in browser memory. Your client's confidential copywriting and unreleased design assets never touch our servers.
Under the Hood
The client-side rendering pipeline powering Lumist Frame.
SVG ForeignObject Canvas
Rather than relying on heavy server-side headless browsers (like Puppeteer) which lag and raise privacy concerns, Frame uses a clever SVG-to-canvas rendering technique. It loads custom HTML/CSS layouts into an SVG <foreignObject> element, and compiles it locally to a high-res PNG in memory.
High-Fidelity UI Mockups
Our social ad previews (Facebook, Instagram, LinkedIn, Google) are built using standard, responsive CSS structures that perfectly match live browser renders, ensuring your clients get a pixel-perfect representation of their live campaign.
Frequently Asked Questions
Are my graphics or campaign briefs stored anywhere?
No. Because files are incredibly heavy, storing them in your browser’s IndexedDB would rapidly consume storage. Frame operates as a completely stateless utility. Everything is rendered directly in your browser's active RAM memory and destroyed when the tab is closed.
Why use Frame instead of taking raw screenshots?
A raw screenshot looks unpolished in client slide decks or portfolio galleries. Frame wraps your raw images in high-fidelity browser or mobile containers and places them on sleek gradient backgrounds, instantly raising the perceived value of your work.
