Frequently Asked Questions
How does the image upscaler work?▼
It draws your image onto a larger canvas using the browser's highest-quality interpolation algorithm (imageSmoothingQuality: 'high'). This produces a clean, smooth enlargement without pixelation artifacts.
What scale options are available?▼
You can upscale images by 2x, 3x, or 4x their original dimensions. For example, a 500x500 image at 4x becomes 2000x2000.
Is my image kept private?▼
Yes. All processing happens locally in your browser. Your image is never uploaded to any server.
Will the quality be as good as AI upscaling?▼
Our tool uses the browser's best interpolation for clean results. For photorealistic AI super-resolution, you would need a dedicated AI model, but this tool delivers great results for most use cases — especially illustrations, logos, and screenshots.
