  3. Run resampling in your browser, review the larger result, and download it.

Overview

Enlarge an image with predictable browser resampling

Increase image dimensions with Canvas scaling and choose the output format and quality. This tool does not invent new detail with a generative AI model, so high scales can make existing compression artifacts more visible.
