Frequently Asked Questions
How does image upscaling work?+
The tool enlarges your image using advanced canvas interpolation algorithms. Smooth mode uses high-quality bicubic interpolation, Sharp mode applies a sharpening filter after upscaling, and Pixel Art mode uses nearest-neighbor for crisp pixel edges.
Will upscaling make a blurry image sharp?+
Upscaling increases resolution but can't add detail that wasn't in the original image. A small, clear image will upscale well. A blurry or very low-resolution image will remain soft. For best results, start with the highest quality source you have.
What's the maximum upscale size?+
You can upscale up to 4x the original dimensions. For example, a 500x500 image can become 2000x2000. Very large outputs may take a moment to process.
Is my image uploaded anywhere?+
No. All processing happens locally in your browser using the Canvas API. Your image never leaves your device.
When should I use Pixel Art mode?+
Use Pixel Art (Nearest Neighbor) mode when upscaling pixel art, retro game sprites, or any image where you want to preserve hard pixel edges without blurring or smoothing.
What output formats are available?+
You can download the upscaled image as PNG (lossless, best quality) or JPG (smaller file size). PNG is recommended for graphics and pixel art, JPG for photographs.
