AI Image Upscaler
Upscales low-resolution images using AI. Unlike a plain resize, it reconstructs missing pixels intelligently instead of just blurring them.
What it does
Use this to turn old 480p phone shots into HD, scale a tiny logo up for print, or sharpen a screenshot for social media. A normal Resizer makes things blurry when going larger - this one tries to invent realistic detail.
How to use
- Drag low-resolution images into the list.
- Pick a Scale Factor: 2x, 3x or 4x.
- Pick an AI Engine: FSRCNN (fast), ESPCN, LapSRN (best quality).
- Click Run.
You get one upscaled copy per image.
Scale factors
| Factor | Result |
|---|---|
| 2x | Twice the size. 500x500 becomes 1000x1000. Fastest. |
| 3x | Three times. 500x500 becomes 1500x1500. Balanced. |
| 4x | Four times. 500x500 becomes 2000x2000. Most detail. |
AI engines
| Engine | Trait |
|---|---|
| FSRCNN | Fastest, lightweight. Good general-purpose pick. |
| ESPCN | Balance of speed and quality. |
| LapSRN | Highest quality, slowest. Pick this when detail really matters. |
Examples
Old phone photos into HD: Add the photos, 4x, FSRCNN, run. 480p becomes near-1920p quality.
Scale a small logo for print: Add the logo, 4x, LapSRN, run. No more visible pixels at print size.
Sharpen a screenshot for social: Add the image, 2x, FSRCNN, run.
Digitise old family photos: Add the scans, 3x, LapSRN, run.
Watch out
- On first use the AI model is downloaded (about 1-5 MB). After that it runs fast.
- Very large images can take minutes.
- Running 4x on an already-high-resolution image produces huge files.
- The AI cannot work miracles on heavily blurred or broken images, it just enhances what is there.
- Faces can sometimes get an "AI plastic" look, not entirely natural.
- A GPU is used automatically if available, otherwise CPU mode is slower.
