Benefits
Reduce image file size in the browser with local preview, quality controls, and ZIP-ready batch export.
Preview the image, watch file size change, and avoid blindly re-saving through multiple external tools.
Use quality and dimensions together, because aggressive quality loss alone is rarely the cleanest path to a smaller file.
The queue makes it practical to compress folders of images and package the results in one download.
Tradeoffs
The tradeoff may be compression artifacts, reduced dimensions, or a format shift. The page makes those choices visible instead of hiding them.
JPG is predictable for broad compatibility, WebP is usually smaller for the web, and PNG is better kept for assets that need lossless edges or alpha.
Exact file-size targets can be approached, but some images still need a gentler dimension change to hit strict upload limits cleanly.

The smallest file is not always the best file. Start with moderate compression, then lower dimensions or switch format only when the destination really needs it.
