:zap: Proxy that compresses images to low-resolution
This data compression service is used by
Bandwidth Hero browser extension. It compresses given
image to low-res WebP or JPEG image. Optionally it also
converts image to greyscale to save even more data.
It downloads original image and transforms it with Sharp on the
fly without saving images on disk.
This is NOT an anonymizing proxy — it downloads images on user’s behalf, passing cookies
and user’s IP address through to the origin host.
You can deploy this service to Heroku:
Data compression service is a Node.js app which you can run on any server that supports Node.js.
