Frequently asked questions
Everything you need to know about Keen.
We use SeedVR2, a state-of-the-art super-resolution model. It analyzes your image and intelligently reconstructs detail, texture, and sharpness — producing results that look naturally high-resolution rather than artificially sharpened.
We support JPG, PNG, and WebP files up to 25MB. The output is always a high-quality PNG to preserve every detail of the upscaled result.
Most images process in under 10 seconds. During peak times, jobs may queue briefly — you'll see your position in line and can close the tab while it processes.
2x doubles your image dimensions (e.g. 512×512 → 1024×1024). 4x quadruples them (512×512 → 2048×2048). Pro and Ultra plans unlock 4x for when you need maximum resolution.
Ultra subscribers get API access included — your 800 monthly images work via both the web app and API. Need more? Additional images are $0.05 each, billed per use. You can also use the API on a pure pay-per-use basis without a subscription.
On Free and Pro plans, you'll need to wait until next month or upgrade. On Ultra, you can keep going at $0.05 per additional image — no interruption to your workflow.
