    That’s why I always prefer an offline converter. Also if your upload a file somewhere the website can save it for their own purpose alhough they say they won’t do it.

      Precisely, and this is why I’ve never trusted online “free” converters since day one. Who the fuck knows what they’re actually doing with your file, and I always assumed that most of them were fronts to steal data and IP from users who are stupid enough to upload corporate and business stuff to them.

      Anyway, there’s vanishingly little I haven’t been able to do over the years with ffmpeg or Imagemagick, their byzantine command line structures notwithstanding.

        Which is why I’ve been happy to trust them for files nobody cares about, like a random audio file that I got off the Internet. And it’s very unlikely they’d be able to exploit my media player.

      I tend to just whip up a script of some sort that employs widely used libraries for the conversion. I know that’s more technical than most people would have the tolerance or aptitude for, but for me, it’s the least ambiguous and most secure way to do stuff like that. And then I can squirrel it away in a utility scripts directory and use it later if I need it again.

      The website mentions that there are fake offline converters that push malware as well.

      Which offline converter? I find myself often trying to convert:

      • PDF to JPEG
      • AVC to MP4
      • OPUS to MP3

      etc. I have no idea how to do that but if I type it into a search engine there’s usually tools there.

        FFmpeg and handbrake do the latter two quite handily. The latter even has a nice program interface, rather than needing commands.

        ImageMagick is capable of the first. I’ve had it go the other way before, and I should be most surprised if it couldn’t convert a PDF to a jpg.

                Let me tell you a little bit about all those various file converter tools, be it ffmpeg, pandoc, imagemagick, whatever.

                The majority of them can be used like this: magick inputfile.bmp outputfile.jpg. If all you need is this file in that format, that’s how you do it. They’re ridicluously capable, you can do editing and compositing and such with them and whatever. If you have a use case where you do that a lot, like you just always put a watermark on images or you always desaturate them or whatever, you can write a script, then just run that script.

                They’re basically all like that. Fairly simple to use for basic format translation, shockingly capable if you want to write a script.

            Handbrake has a GUI, and it’s relatively straightforward to use. VLC also works well. You can also use ffmpeg on the CLI like so:

            ffmpeg -i input_video.mp4 output_video.avi
            

            imagemagick isn’t really that hard, in most cases it’s:

            convert <file1> <file2>
            

            For example:

            convert file.pdf file.jpg
            

            If that doesn’t work, try pdftoppm:

            pdftoppm input.pdf outputname -png
            

            I don’t know of a good GUI for it, I recommend just learning to use either imagemagick or pdftoppm.

              I downloaded it and it immediately did not work so I’m gonna have to disagree with you there, champ.

              You can also use ffmpeg on the CLI like so:

              I’ve lost far too many hours to the CLI. I don’t fall for that trick anymore.

                You do you, I guess. Those are incredibly simple commands I provided, and you can intuit pretty easily how to tweak them for other formats.

                I guess it’s up to you. You can gamble with random services online, or you can spend a few minutes and learn to use a tool that’s all but guaranteed to not have malware.

                  or you can spend a few minutes

                  This is just a fucking lie and I’m tired of hearing it. What did I just say?

                  I’ve lost far too many hours to the CLI.

                  I’ve tried to learn this shit. It’s a fucking rabbit hole. I type these commands, letter for letter, the terminal returns some completely useless error that provides me with no diagnostic information whatsoever, I spend hours searching and trying to understand why and come up empty-handed. I don’t have time for that anymore. I already have multiple jobs. It’s not how I prefer to spend my free time. And frankly, I don’t believe it anymore when software engineers feed me this bullshit.

                  You know what those web services do? I just click a button and it does what the button says. Why is that so hard?

                    There’s also a pretty big chance that they’ll do more than what the button says, like inject malware. That’s the whole point of the article.

        I can’t comment on the others, but PDF to JPEG should be easy enough. ImageMagick, which another commenter suggested, is possible but not user friendly. However you can just open the PDF in many applications and export it as an image. Adobe Acrobat and Photoshop can do it. GIMP probably too.

        I’m a last ditch effort you can even just open the file and screenshot it.

        imagemagick handles almost all image files

        images ) ls
        001.jpg  002.jpg  003.jpg  004.jpg  005.jpg
        images ) convert 001.jpg example.pdf
        

        ffmpeg handles almost all video files

        ex ) ls
        rock.mp4
        ex ) ffmpeg -i rock.mp4 rock.avi
        

        if you use gnome there’s a nice little feature of the file explorer where you can just drag and drop scripts into ~/.local/share/nautilus/scripts/

        for example

        make a fish script (ignoring error checking for brevity here, my real script had a couple guard rails)

        /#!/usr/bin/env fish
        set file $argv[1]
        convert $file (basename $file .png).pdf
        

        then when you right click on a file in your gnome file explorer you can click the scripts option

        example

        and the script is right there so you can just easily convert with the press of a button

        example

        note, i crossed out some stuff that includes client names

        tldr: there are so many ways to do what you need to do there’s no reason to trust random websites you don’t know. there’s a lot of slimey people out there wanting to take advantage of people. and everybody should strive to be at least a little computer literate. the examples i gave here aren’t complicated. they’re simple commands
