Increase Image Resolution — Magnify 2x-4x Without Pixelation

Old photos look blurry? Online graphics have too low of a resolution? PixLocal utilizes Real-ESRGAN technology to upscale your image resolution by 2x or 4x while maintaining sharp details — running completely free in your browser.

Real-ESRGAN Technology

PixLocal integrates Real-ESRGAN x4v3 — one of the world's leading upscaling algorithms. Trained on millions of low-res/high-res image pairs, this technology is capable of:

• Recreating fine details that do not exist in the original low-res file
• Smoothing out JPEG compression artifacts
• Preserving sharp edges instead of blurring them like traditional bicubic interpolation
• Handling real-world degradation effectively

How It Works

Tile-Based Processing

For larger images, PixLocal divides the file into smaller tiles, upscales each tile individually, and stitches them back together. This technique allows processing of very high-resolution images without crashing your device's memory.

Workflow

1. Upload image — Select the photo you wish to enlarge
2. Choose scale factor — 2x (double the size) or 4x (four times the size)
3. Processing — Analyzes and reconstructs detail
4. Download result — HD image ready to use

Applications

• Restore Old Photos: Enlarge family archives or low-quality memorabilia
• Product Images: Increase resolution for e-commerce photos that need zoom capabilities
• Graphic Design: Scale up small graphics for use in banners or posters
• Social Media: Enhance blurry thumbnails or profile pictures
• Printing: Boost DPI to achieve crisp offset print quality

Comparison: 2x vs 4x

Notes

• Larger images take longer to process
• The model engine downloads on the first run and caches locally — subsequent runs are much faster
• Results depend on the quality of the source image — extremely blurred or severely damaged photos have limitations
