AI Image Tools
Lightroom Denoise works only on raw files and needs a paid subscription. For JPG, PNG and phone photos there is a free online option. Compare them, plus how to speed up Lightroom Denoise.
Lightroom's Denoise AI is excellent on raw files, but it does not work on JPEG, PNG, TIFF or HEIC — for those, a browser AI denoiser like imgmend is the practical free choice.
| Quick Comparison | Lightroom Denoise | imgmend denoiser |
|---|---|---|
| Works on | Raw files and some raw-based DNGs | JPG, PNG, WEBP up to 10 MB |
| Cost | Adobe subscription | 3 free/day; $9.90 one-time Pro |
| Install | Lightroom (Classic or cloud) | None, browser |
| Output | A new, denoised DNG | A cleaned image download |
| Speed | Depends on your GPU | About 10 to 30 seconds on the server |
Why Lightroom Denoise Skips JPEGs
According to Adobe's documentation and community discussion, Denoise works from raw sensor data before demosaicing, which is why already-rendered files such as JPEG, PNG, TIFF and HEIC are not supported. The list of supported raw types has grown over time, so check Adobe's current help page for your camera.
How to Denoise Faster in Lightroom
- Use a capable GPU and keep drivers up to date: this is the biggest factor.
- Batch it. Select several raw photos and apply Enhance → Denoise in one go, then do something else while it runs.
- Denoise only the keepers. Cull first so you do not spend time on rejects.
- Start at the default amount and raise it only if needed: heavier settings take no less time and can look plastic.
What If Your Photo Is a JPEG or Phone Image?
- Open the grain remover or the home page denoiser.
- Upload the JPG, PNG or WEBP.
- Wait 10 to 30 seconds while Real-ESRGAN removes noise, grain and compression artifacts.
- Compare with the before and after slider and download.
Free downloads carry a small imgmend watermark; Pro removes it. Images above roughly 2 megapixels are scaled down before processing, so for very large files denoise in your editor or with a desktop tool.
Which Should You Use?
| Situation | Best choice |
|---|---|
| Shooting raw, already in Lightroom | Lightroom Denoise |
| Only have JPEGs or phone photos | imgmend |
| Old scans or compressed images | imgmend, then compressed image repair |
| Hundreds of raw files | Lightroom batch Denoise |
