Directly enlarging a small image often makes pixels and edges look blurry, especially in thumbnails or article images. This tool helps you enlarge low-resolution images with less visible quality loss by scaling them and applying optional sharpening or noise reduction.
Key features
- 2x, 3x, and 4x image upscaling
- Sharpening and noise-reduction options
- Output resolution, file size, and enhancement summary
- Private browser-based processing and PNG download
How to use
- Upload a PNG, JPEG, or WebP image.
- Choose an upscale factor from 2x to 4x, or select 1x to enhance without enlarging.
- Choose sharpening or noise reduction, then run the enhancement.
- Review the preview and output details, then download the enhanced PNG.
Practical tips and limits
- Start with 2x for a natural-looking result, then test 3x or 4x only when needed.
- Use noise reduction for grainy photos. For text and logos, try sharpening alone first.
- Output is limited to 12 megapixels to prevent the browser from becoming unresponsive. Choose a lower scale if the selected output exceeds the limit.
- After upscaling, use the PNG Compressor to reduce the output file size.
Summary
Use this image upscaler when a small source image is difficult to reuse. It provides a quick way to enlarge, enhance, preview, and download an image without uploading it to a server.
