Export formats and image quality
Understanding Lume's output format and template canvas sizes
Quick Answer
Lume exports all generated images as PNG files at one of three resolutions: 1K (1024px), 2K (2048px), or 4K (4096px) on the longest edge. Each template has a preset aspect ratio (square, portrait, or landscape) that is optimized for the scene. Pick the resolution from the editor toolbar before you generate, 1K on every plan, 2K and 4K on Business, Growth, and Studio.
Export Format
PNG, Lossless
All Lume generations are exported as PNG files for maximum quality and compatibility, at the resolution you select before generating.
Output Resolution
Pick a resolution from the toolbar before you generate. The aspect ratio always comes from the template; the resolution sets how many pixels long the longest edge is. 1K is included on every plan; 2K and 4K are on Business, Growth, and Studio.

Template Aspect Ratios
Each template is built for a specific aspect ratio. Pixel dimensions scale up automatically when you choose 2K or 4K, the long edge below shows the 1K baseline.
Square (1:1), baseline 1024x1024
The most common format. Ideal for product listings on Shopify, Amazon, Etsy, and social media posts. Scales to 2048x2048 (2K) or 4096x4096 (4K).
Portrait (2:3), baseline 1024x1536
Vertical format suited for tall products or scenes with vertical compositions. Scales up proportionally at 2K and 4K.
Landscape (3:2), baseline 1536x1024
Wide format for scenes that benefit from a horizontal composition. Scales up proportionally at 2K and 4K.
