I also use Caesium Image Compressor on my ROMs and Themes folder to reduce their size and improve the RG35XX's responsiveness. Source: about 1 year ago

If you want further compression you could check out Caesium Image Compressor which is free (and I'm not affiliated with it incidentally, I just like it). Source: about 1 year ago

Try an image compression tool, this one is free and open source: https://saerasoft.com/caesium/. Source: over 1 year ago

Caesium Image Compressor can do the job and it is easy to use. There is also imagemagick which is basically the swiss-knife for image editing, but based on you having looked for websites first, I assume you don't look for a commandline tool (imagemagick is a commandline tool).

I can recommend Caesium , a utility (Windows, MAC version in Alpha test) to remove all EXIF, metadata etc which will reduce your JPG in size quite a lot without using higher JPG-compression (lower quality). Source: almost 3 years ago

I use Skanect with my high school students. Like others said, it's pretty blobby, but works for miniatures that I make the kids. I'm not sure if it still exists after the buyout, but the "try" version used to be free with the caveat of only being a 5000 poly export (I usually export at around a million for my models).

Skanect works the best, but you also need to install the OpenNI2 drivers. Skanect is also a paid program, in theory, although you can eternally use the trial version just fine if you know how to be creative with the options the trial version freely offers., last I knew. I liked it enough to purchase the most recent version after skimming by with the workarounds for a while. Source: almost 3 years ago

I got the pro version of Skanect 1.11 from: Https://skanect.occipital.com/. Source: almost 3 years ago
