One pass that sharpens detail, lifts exposure and cleans up JPEG artefacts.
'Low quality' usually means three things at once: soft focus, heavy compression and a dull exposure. Sharpening alone makes the first worse and the second much worse, because it amplifies the blocky edges JPEG left behind.
Real-ESRGAN was trained on degraded images specifically, so it reconstructs detail while suppressing the artefacts instead of sharpening them. It is the same family of model behind most paid 'HD photo' apps.
Upload the photo: Small, old or heavily compressed images benefit most. Screenshots and scans work too.
Run the enhance pass: One credit. Nothing to configure — the model reads the degradation from the image itself.
Upscale if you need size: Enhancement fixes quality; the upscaler adds resolution. Running both gives a print-ready file.
Artefacts, not just sharpness: Compression blocks and colour banding are cleaned rather than accentuated.
Cheapest tool on the site: 1 credit, so ten free enhancements a day on a free account.
Pairs with the upscaler: Enhance first, then upscale — the order matters for a clean result.
How can I improve image quality for free? Signed-in accounts get 10 free credits every day, and new users can try Pro free for 24 hours — cancel anytime.
Is this the same as upscaling? No. Enhancement repairs quality at the current size; upscaling increases resolution. They are separate tools and often used together.
Will it change faces? The enhancer is non-generative, so features are reconstructed, not reinvented. For heavy face damage, use the restore tool.
What is the maximum size? Up to your plan's resolution limit — 2K on free, 4K on paid plans.
