Image enhancer
AI image enhancer and upscaler
Make small or soft images usable again. ZeoCanvas’s enhancer upscales a picture 2× or 4× with a Real-ESRGAN super-resolution model, which reconstructs detail instead of simply stretching pixels.
Follow up with sharpening, noise reduction and colour adjustments to finish the image.

Features of the Image Enhancer
AI upscaling 2× and 4×
A super-resolution model adds plausible detail when enlarging, unlike ordinary resizing.
Denoise and sharpen
Reduce grain from low-light photos and bring back crispness after upscaling.
Light and colour fixes
Exposure, highlights, shadows, contrast and white balance in the same editor.
Runs on your device
The model runs in the browser — WebGPU where supported, otherwise the CPU.
How to use the Image Enhancer
- 1
Open your image
Upload the photo and choose the Enhance tool.
- 2
Upscale with AI
Pick AI 2× or 4×. Large images are processed in tiles to keep memory use in check.
- 3
Fine-tune and apply
Add sharpening or noise reduction, compare with the original and apply.
Upscaling versus resizing
Resizing makes an image bigger by interpolating between existing pixels, which looks soft. AI upscaling predicts the missing detail — edges, textures and lettering — based on what it has learned from many images, producing a sharper result at the larger size.
- Use AI upscaling for small images you need to print or show large
- Use plain resizing when you only need a smaller file
Know the limits
Super-resolution cannot recover information that is completely missing. Heavily compressed or blurred photos improve but will not look like they were taken with a better camera. Processing time depends on your device.
Frequently asked questions
How large can I upscale?
Up to 4×. Very large outputs are limited by your device’s memory, and the editor tells you if a size is too large.
Is the enhancer free?
Yes. It runs on your device, so there are no per-image charges.
Does it change faces?
The model enhances general detail; it is not a face-generation model and does not invent new facial features.
