Frequently Asked Questions
What upscaling method is used?
This tool uses high-quality bicubic interpolation via the browser Canvas API. It produces smooth results for photos and graphics.
How much larger will the file be?
A 2x upscale produces an image with 4x the pixels. A 4x upscale produces 16x the pixels. File size increases proportionally.
Will the image look sharper?
Upscaling with interpolation makes images larger but cannot add detail that was not in the original. For best results, start with a high-quality source image.
What formats are supported?
JPG, PNG, and WebP images are supported as input. The output is always saved as PNG for maximum quality.
