如何使用 Image Upscaler

Upload an image, choose an upscale factor, and preview the larger target dimensions before export. This tool is useful for thumbnails, product images, social graphics, logos, and other assets that need to be enlarged without blindly stretching them. The best results come from reasonably clean source images rather than tiny heavily compressed originals.

1

Upload the image

Choose a JPG, PNG, or WebP image you want to upscale.

2

Pick an upscale factor

Choose a practical enlargement size like 2×, 3×, or 4× depending on your target use case.

3

Review the output dimensions

Check the preview size so you know the expected larger resolution before export.

4

Export the upscaled image

Generate the larger image and review it at real display size before publishing or printing.

常见问题

Can this make a tiny image look perfect?+
Not always. Upscaling can help, but very small or heavily compressed images still have limited source detail.
Which upscale factor should I choose?+
2× is usually the safest default. Higher factors can be useful, but they also expose source-image limitations faster.
Does this upload my image anywhere?+
No. The upscaling workflow is designed to run locally in your browser during normal use.
What images benefit most from upscaling?+
Clean product shots, graphics, logos, screenshots, and decent-quality web images usually benefit more than noisy or heavily artifacted files.
