✓ Works best with
- In-focus photos with low-light noise
- Night shots from a phone, high ISO, scans
- Fine grain over an otherwise sharp subject
✗ Can't recover
- Motion blur or missing focus
- JPEGs wrecked by compression
- At full strength it can smooth skin and textures
We measured it
- Noise removed from a 1600 × 1200 px photo in 5 seconds. (19-09-2026)
Measured on airpic.app with the GPU already running. If nobody has used it for a while, the first job takes 40 to 90 seconds longer to start.
Frequently asked questions
What kind of noise does it remove?
High-ISO grain, low-light noise and color noise. SCUNet model trained for photographic denoising.
Will I lose detail?
The model prioritizes real edges and textures; on very fine grain it may smooth. For maximum detail, combine with Upscaler.
Can I control how much noise is removed?
Yes, with the strength control: at 100 % the SCUNet model (trained on real camera noise) cleans fully; at 50 % it keeps some grain and texture. Ideal for high-ISO photos you don't want to look “plastic”.
Is anything stored?
Nothing: ephemeral processing, deleted 1 hour after download.
Is it free to remove noise from a photo?
Processing and previewing the result is free, with no account. You get 1 free full-size download every month; after that you pay with credits that never expire, no subscription.
Are there settings for different kinds of photo?
Yes: there are quick presets for night photos, high ISO, scans and keeping texture. They set the recommended strength, and you can then adjust it by hand.
Can I upload a RAW file?
No: it accepts JPG, PNG (16-bit too), WebP, TIFF, HEIC and AVIF. Export the RAW to 16-bit TIFF or PNG so you don't lose information before denoising.
