When to resize
Use it before uploading to a CMS, before emailing, before sharing on chat apps that re-compress aggressively, or to prepare different sizes for responsive layouts. Resize once, ship a smaller file — the receiver doesn't pay for pixels they never see.
How it works
Each photo is decoded with the browser's native image pipeline, resampled with a high-quality 2D-canvas downscaler, then re-encoded in its source format. No server is involved.
