Best practices for image upscaling
- Start with the highest-quality source image you have — AI upscaling enhances existing detail but cannot invent completely missing information.
- Use 4x for close-up product shots, faces, and text-heavy images where fine detail matters.
- Use 2x for social media thumbnails, blog headers, and any use case where file size is a concern.
- For ecommerce, upscale before adding white backgrounds or compositing — cleaner edges make later editing easier.
- PNG output preserves detail and color best for before/after quality checks and editing workflows.
