Privacy

Compression without the vague parts.

Images travel over HTTPS to a Cloudflare Worker and on to TinyPNG for perceptual optimization. The Worker processes bytes in memory and keeps no image copy. If a result still exceeds your limit, the browser re-encodes it locally and adjusts dimensions only as needed.
