Guertzli JPEG Encoder - smaller JPEG filesize (up to 35%)

[masterjp]

Here is an article about a new JPEG Encoder - Guetzli JPEG Encoder. It produces up to 35% smaller files by better compression.
The pictures have fewer artifacts than standard jpegs.
The algorithm is open source and you can find it at github. Demo programs for Windows, Linux, etc. (32 or 64bit) are also available.
The results will be fantastic, if you have big jpeg file (e.g. 5 MB jpeg compressed to 1-2 MB.).
The only disadvantage is the slower speed of the jpeg encoder. The reason is the missing multi core support. It takes much time.

+1 as an option

Good Idea.
Here another SSIM compressor for JPEG:

Really powerful.

so an option in jpeg setting to use this encoder?

[m.Th.]

yes, IMHO ...with a proper caption: "Use Guertzli Encoder (smaller files, slower saves)" - this is exactly how Photoshop writes it (in other cases, of course).

'Guertzli Encoder' exists in PS?

Not the codec itself, just the language. In the image below it explains very clearly what RLE and ZIP do from the user's perspective:

Compression types.jpg (8.17 KiB) Viewed 2287 times

IMHO this kind of text we need here.

In fact, it could be there a check box in order to activate it, near the already present:
Progressive, Optimise Huffman table, Remove all Metadata, Rebuild embedded thumbnail, etc...

Personally I never tried the Guertzli Encoder, but the jpeg-archive yes. And I can tell you that there is a visible difference.

ok, but it will perhaps better to have Guertzli as Tools, because often users want to recompress files without opening them

Perhaps. But surely we need it as an option for saving. Batch Convert / Save / Save As... / Export etc.

+1 - Guertzli as additional would be great!
