Useful compression for everyday image work

The goal is not to hide the controls. You can choose the output format, resize oversized photos, and keep a clear before-and-after size comparison.

For website owners

Large images often slow down landing pages, blog posts, product pages, and portfolios. Smaller assets can improve load time and reduce bandwidth use.

For forms and email

Many application forms, support portals, and email systems reject large files. Compress images before attaching them to avoid failed uploads.

For privacy

Canvas re-encoding removes most camera metadata from exported images. Since files are not uploaded, private photos do not leave your browser.
