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.

Client testimonial
“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.”
