You won't be able to do that with RAR files either. The only archive/compression format that you can send anyone is ZIP, since both Windows and macOS can open them ootb.

I wouldn't send a RAR to my grandparents, but if I had to send pictures for a school reunion I would expect everyone to either know how to open a RAR or to be able to figure it out. Worst case they will google rar and will find WinRAR as the first result. For zstd or brotli I can't even name a GUI program able to open them outside a somewhat obscure 7zip fork.

  Why would you try to compress pictures....in your case zip is as good as everything else (and less problematic to open)

    Or if your friends all have WinZip and can tolerate .zipx (which is a file extension for later and thus less interoperable version of ZIP), it does support JPEG recompression so it can be actually better than RAR.

      Any lossy compression format it's crap.
      - lifthrasiir 5y ago
        No, JPEG recompression I meant is not lossy here; it is essentially taking the internal JPEG data structure and losslessly compressing them in more modern techniques. If you want there is also an open source algorithm [1] developed and used by Dropbox. [1] https://github.com/dropbox/lepton https://github.com/dropbox/lepton

    Ok, bad example, imagine I would be sending you ... text files or something. The point I was trying to make was how viable it is, not how useful it is.
    - nix23 5y ago
      Yes please zip there too since i don't think it would be gigabytes of text. If sending gigabytes of text please use lzip ;)

        I know it's not pretty much used...but it's a great format for "important information" as you can read here: https://en.wikipedia.org/wiki/Lzip#Application https://en.wikipedia.org/wiki/Lzip#Application https://www.nongnu.org/lzip/xz_inadequate.html https://www.nongnu.org/lzip/xz_inadequate.html https://parltrack.org/dumps https://parltrack.org/dumps

  If you sent me a RAR, I'd remind you that it's the 21st century, we all have really fast Internet these days compared to the 90s when RAR was released, and I really don't want to have to install a new piece of software just to open your photos. (The best bit is that the official WinRAR Linux distribution is a .tar.gz) Just use ZIP unless your classmates are working solely via tethered 2G connections in Tierra Del Fuego.

Except that... non ascii character filename went wrong all the time. Because zip did not enforce a charset. A rar or 7z won't mess up your filename in any case in contrast to zip.
