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 than 800? Contact us about enterprise pricing at $0.05 per image for any volume.
Yes! Keen is built for agents. Use our MCP server for Claude/Cursor, or the x402 payment endpoint for autonomous agents that pay per-image with USDC — no account needed. See our For Agents page for integration guides.
On Free and Pro plans, you'll need to wait until next month or upgrade. Ultra has 800 images per month. Need even more? Contact us about enterprise plans.
