Grain gone, details kept
An open-source AI model (NAFNet, trained on real smartphone noise) cleans the photo on our server: it removes grain and colour speckles and keeps edges sharp. The grain in this photo was added for the demo. Drag to compare.

How to remove noise from a photo
Add your images
Choose up to 10 JPG, PNG, WebP or AVIF files, drop them on the page or paste one.
The AI cleans them
The model removes grain and colour noise and keeps the edges; a photo over 4 megapixels is scaled to 4 first.
Compare and save
Drag to compare with the original, then save each image or all of them in a ZIP.
More about removing noise
What the denoiser fixes
| Problem | Looks like | Result |
|---|---|---|
| Low-light grain | Sand-like specks in dark areas | Smooth dark areas, sharp edges |
| Colour noise | Red, green and blue dots | Even colours |
| High-ISO phone photos | Grainy night and indoor shots | Cleaner, as if shot in better light |
| Light JPEG blockiness | Small blocks around edges | Softened; heavy blocks may remain |
Noise can't hide detail that was never captured: a very dark or blurred photo gets cleaner, not sharper. On a photo with no noise, the model can soften fine texture a little.
Getting the best result
- Start from the original. A photo sent through a chat app is already compressed: its noise is mixed with blocks.
- Denoise before you edit. Brightening a dark photo makes grain stronger: remove it first, then adjust.
- Use it on noisy photos. Night, indoor and high-ISO shots gain the most; clean daylight photos don't need it.
- Make it light before it goes online. Save as WebP or compress the result to keep the page fast.
Your images are never stored
To remove the noise, the image is sent to our server over an encrypted connection, cleaned in memory and deleted as soon as the result is sent back. It is never stored, logged or seen by anyone.
Questions about removing noise
Is it free? Are there limits?
It is free, with no sign-up and no watermark. You can clean up to 10 images at a time and 50 an hour.
Does the result keep the full size?
Yes, up to 4 megapixels. A bigger photo, such as a 12-megapixel phone shot, is scaled down to 4 megapixels first, and the result says so.
Which kinds of noise does it remove?
Grain from low light and high ISO, colour speckles, and light JPEG blockiness. It works best on phone and camera photos taken in dim light.
Will it make my photo sharper?
It makes it cleaner, not sharper: edges are kept, but detail that was never captured can't come back. For a bigger, sharper image, use the upscaler.
Which AI model is used?
NAFNet, an open-source model by Megvii (MIT licence) trained on real smartphone noise, running on our own server.
Are my photos uploaded?
Yes, each image is sent to our server, processed in memory and deleted at once. Nothing is stored and no one sees it.
How long does it take?
About 5–8 seconds for a 1-megapixel photo and up to about 30 seconds at 4 megapixels. Images are done one after another.
Is transparency kept?
Yes. A PNG, WebP or AVIF with a transparent background stays transparent; JPG has no transparency, so it becomes white.
