One Asset.
Every Platform.
Drop in a single image. Drag to frame it perfectly for OpenGraph, Product Hunt, Dribbble, and Favicons simultaneously, and batch-export them instantly using your local GPU.
Batch Generation
Select multiple targets (Twitter, Instagram, Dribbble). Scale generates exact bounding boxes for you to pan and crop simultaneously.
Interactive Panning
No stupid automated center-crops. Drag your image within each frame to perfectly position your subject before exporting.
Hardware Accelerated
Utilizes the browser's native HTML5 Canvas API to render and crop high-res imagery using your device's local GPU without cloud servers.
Under the Hood
The architecture powering Lumist Scale.
Zero-Server Operations
Your pre-release SaaS dashboards and proprietary designs never leave your machine. Images are ingested as local Blob URLs and processed entirely client-side.
Virtual Offsets
When you drag an image in the workspace, Scale uses CSS transforms to maintain 60fps performance. Only when you click "Export" does it calculate the mathematical offsets to paint the actual pixels to a hidden canvas.
Frequently Asked Questions
Can I zoom in on the crop?
Yes. Each target platform frame includes its own independent zoom slider and panning coordinates, ensuring you get the perfect crop for every aspect ratio.
Does this integrate with Lumist Crush?
While they act as independent utilities, we highly recommend cropping your master assets in Scale first, and then dropping the exported PNGs into Lumist Crush to convert them to WebP and strip EXIF data before uploading to your server.
