How to upscale an image without losing quality

Stretching a small image in a normal editor just makes it blurry. AI upscaling is different: it reconstructs plausible detail, so the result looks sharp rather than soft.

Step by step

1. 1Open the AI Image Upscaler and drop, browse, or paste your image (PNG, JPG, or WebP).
2. 2Pick a model — General is best for photos; Ultra Sharp maximises crispness; Anime suits illustrations and line art.
3. 3Choose 2× or 4×, then run it. Drag the before/after slider to compare the result against the original.
4. 4Download the upscaled PNG.

When to use which factor

Use 2× for a gentle, natural boost and 4× when you need a big enlargement (printing, large displays). Very large images take longer, especially without a WebGPU-capable GPU — the tool falls back to CPU automatically.
