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: over 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 will assume that the average effective broadband connection is about 20 MB/s, and both xz and zstd decompressions are faster than the download under this assumption. But there are lesser known compression algorithms that are more efficient in terms of compression ratio for this target decompression speed, like zpaq [1], which are rarely considered as alternatives. So multiple factors exist here and I believe... - Source: Hacker News / 2 months ago

My best bet is some data corrupted when plugging into windows. If it still works in windows I strongly recommend you backup important data on your drive. You can use 7z to compress, or zpaq which can achieve incredible compression rate in some cases. Source: 12 months ago

Yes, you can find more information on how it works on the zpaq's author website http://mattmahoney.net/dc/zpaq.html. Source: over 1 year ago

There was a recent essay about the use of the QOI format for software/game assets. They're somewhat bigger than PNGs; however, I discovered that they compress really good with ZPAQ. Source: over 1 year ago

But when you need high compression rates, why not use something more innovative? ZPAQ is amazing - Journaling archiver for incremental backups There are plugins for total commander to ease managing, or gui linked at Matt Mahoney's page It offers better compression ratio than both Winrar and 7-Zip, for even more RAM and time to compress. The amazing part is not wasting energy and storage space for the same... Source: almost 2 years ago
