Project overview
A private, in-browser compressor for WebP, JPEG, and PNG with a live queue, quality control, and one-click ZIP export, no uploads, ever.
The challenge
Creators needed a trustworthy way to shrink large batches of images without uploading sensitive product shots or client assets to a third-party server.
Our solution
We built a Squoosh-style pipeline that runs MozJPEG, libwebp, and PNG codecs entirely in the browser, with a durable queue UI, format conversion, max-dimension caps, and ZIP download.

“Replaced three desktop tools with this. The batch queue plus ZIP download is exactly what we needed for shipping product screenshots, and nothing ever leaves the machine.”
