Performance

Guetzli is intentionally slow — it tries many encodings to find the best compression. Expect processing to take 1 minute or more per megapixel. It is best suited for batch or offline processing, not real-time use.

It also requires a minimum of 300 MB of memory per megapixel of input image.
