Lepton Optimizer Download Free PORTABLE
Anette Bartha
Anytime Google does something new, folks pay attention. Guetzli is no exception to that, but the hype is a bit ridiculous on this one. First of all, Guetzli is NOT a JPG optimizer. Once you've saved a JPG, it is not useful to re-compress the image with Guetzli. It is a JPG compressor, one time only. It is meant to be used when saving a JPG from a PNG image or other lossless/high-quality input. Then, and only then, does it beat "normal" JPG encoders.
Additionally, images produced by Guetzli are not optimized. They can be further compressed by any standard JPG optimizer using progressive encoding. Our favorite JPG encoder is mozjpeg, and to date, I have not seen a better lossless JPG optimizer.
This is a compression technology from Dropbox, and is useful only for compressing JPG images "at rest". While it is lossless, you must also have lepton to decompress and view your JPG. Without the decoder, your JPG images are inaccessible. Dropbox compresses images using lepton when they store them to their servers, and then when you want to download or view a JPG, they decompress it on the fly so you can view it again. There are no browsers, and no system viewers that can display lepton-encoded images natively. So if you want to save backup space and lepton-encode all your images, go right ahead. But don't put lepton-encoded images on your website, no one (including you) will be able to view them in the browser.
