Image Denoiser - Clean Grain Before You Deliver the File
Use this page when the complaint is noise: speckle in shadows, colour blotches in a night photo, grain across a sky. If the problem is softness rather than grain, the AI image sharpener is the shorter route; if the frame is blurry instead of noisy, start at the blurry photo fixer.

Use it when the pixels are already the right size but noisy
Noise is what a sensor records when there is not enough light: film-like grain in the shadows, purple and green speckle in dark areas, and coloured blotches that survive even when the photo looks sharp. Denoising is a judgement call, because every noise reduction also removes a little texture. There is no strength dial here; the model cleans as it rebuilds the image, so the practical lever you control is the scale step and the quality of the file you upload. Test on the worst frame you have, then look at flat areas such as sky, studio backdrops and skin, where leftover speckle and smeared patches are easiest to see.
Best For
The jobs this page is built to handle well
- Night and indoor phone shots with visible grain
- Dark product or interior frames where speckle ruins a clean sweep
- Scans of old prints where paper grain competes with subject detail
Choose Another Page When
These jobs usually need a different workflow
- A file that is merely small: that is an enlargement job
- An image where grain is the intended look, such as film emulation
A sharp but grainy file, ideally the camera original
The same framing with calmer shadows and cleaner colour
Sky, shadows and skin for leftover speckle or smearing
Test the noisiest frame in the set, not an average one
Upload the frame with the worst noise. If shadows come back clean without turning plastic, the rest of the set behaves the same way; if detail vanishes, take a smaller step.

How to Use Image Denoiser
Upscale your images in 3 simple steps
Upload the grainy original
Work from the camera file or the highest-quality export you have, and keep it within 10MB. Recompressing before upload adds new blocking on top of the noise you are fighting.
Start at 2x and judge a flat area
Run 2x first and open the result at 100 percent. Flat areas show the truth: if speckle is gone and texture survives, the file is done. Only raise the step when you also need more pixels.
Keep the version that still has texture
If the result looks waxy, the workflow took more than the file could spare. Re-run from the original at a smaller step, or accept the grain and deliver at the destination size.

Upload a soft or low-resolution photo and let the restoration model rebuild edges and texture while it enlarges. For scanned prints, start with the old photo upscaler; for general enlargement, use the AI image upscaler.
Scanned Photo Enhancer - Fix the Scan, Then Improve the File
Use this page for a scan of a printed photo, whether it came from a flatbed or a phone camera. If the print itself is old, faded or cracked, the old photo upscaler is built for that job; if you are preparing a print-size delivery, continue with the image upscaler for print.
