What is Image Upscaler?
The Image Upscaler enlarges low-resolution images using advanced Lanczos resampling, which preserves sharp edges and fine details better than basic bilinear scaling. Choose 2x, 3x, or 4x upscaling, compare the result side-by-side with the original, and download the high-resolution version.
How to use
- Upload a low-resolution image (PNG, JPG, WebP) — the tool shows its current dimensions and a preview.
- Select your desired scale factor (2x, 3x, or 4x) and click upscale to process the image.
- Compare the original and upscaled versions side-by-side, then download the high-resolution result as PNG.
Result
You have a 200×200 product thumbnail that looks blurry on your website. Upload it, select 4x upscaling, and download an 800×800 version with sharper edges and preserved detail.
