Does this add detail like an AI upscaler?

No. This tool uses the browser's bilinear smoothing — it enlarges without inventing detail. For AI-based super-resolution, use a dedicated tool.

Graphics, logos, screenshots, line art and illustrations. Photographs may look slightly soft when upscaled dramatically.

No. The whole pipeline runs locally with the Canvas API.
