How it works
Convert in three steps

1. Upload your image

Select or drag the low-resolution file (JPG, PNG, or WebP) into the upload box.

2. Select scale multiplier

Choose your target sizing output factor (such as 2x or 4x size).

3. Process and download

Click scale to let the local neural network reconstruct details and save the larger image.

FAQ
Common questions
The upscaler utilizes a specialized super-resolution neural network that runs directly in your web browser via WebAssembly. The model analyzes small pixel grids and reconstructs missing details, edges, and textures locally on your device. Your file is processed entirely in memory without being sent to external servers.
The AI model achieves the best results on digital illustrations, clean graphic designs, and well-lit portrait photos. It can produce blurry or soft textures when processing heavily pixelated screenshots, low-quality memes, or photos with high grain.
To prevent your device web browser from crashing or running out of memory, input images are restricted to a maximum size of 1200 by 1200 pixels. The tool will automatically resize files exceeding this size before beginning the upscale process.
No, the upscale calculations are executed client-side inside your browser session. None of your original images, output graphics, or settings are stored in database logs, keeping your data private.

About the AI Image Upscaler
The AI Image Upscaler is a fast, reliable utility designed for graphic designers, content creators, and print managers who need to increase image sizes. It offers a clean interface to enhance resolution without installing complex desktop applications or paying for cloud processing APIs. Whether preparing illustrations for print or scaling web thumbnails, the tool provides quick results.
Benefits
  • Scale web thumbnails - increase the resolution of low-quality thumbnails to reuse them in high-definition articles.
  • Prepare print graphics - expand illustration dimensions to meet minimum pixel count requirements for physical posters.
  • Enhance vector layouts - upscale rasterized logos and icons to keep edges sharp on modern high-resolution screens.
  • Enlarge old photos - double the size of vintage scans before sharing them with friends or family.
Privacy
Calculations are processed entirely within the local web browser, meaning no image files or upscaled graphics are sent to external servers.
