The Airpic blog
How to get an image ready for whatever you need it for: file formats, printing, online shops and old photographs. With numbers, not adjectives.
Why Airpic
Image upscaling API with no sign-up
Airpic's image upscaling API needs no sign-up, API key or card: a credit code is your bearer token. What you can call, how you pay per download, the limits.
Upscale images for professional printing: Airpic for studios
Upscale images for professional printing up to 600 MP with the ICC profile kept, share one credit code across the studio and automate it with the API.
Which AI models does Airpic use, and under what licence?
Which AI models does Airpic use? Per tool: Real-ESRGAN, GFPGAN v1.4, BiRefNet, DDColor, LaMa and Whisper, with licences, size limits and where they run.
