The file conversion tools I actually reach for (instead of installing FFmpeg again)

Every few months I hit the same wall. A client sends over a .mov file that needs to end up as an .mp4 for a web page, or someone drops a .heic photo in Slack and asks why it "won't open" on their Windows machine. My first instinct used to be brew install ffmpeg and then spend twenty minutes remembering the flags. These days I don't bother unless the job actually needs scripting or batch automation. Here's what's actually in my rotation, and when I reach for each one. When it's a one-off file and I just need it done If I'm not going to touch this format again for another six months, I'm not installing anything.

It's not pretty, but it's reliable and doesn't nag you to create an account. When I need to batch-process a folder This is where the browser tools stop being useful and FFmpeg earns its keep. If I'm converting 200 images or normalizing audio levels across a podcast archive, nothing beats a script I can rerun. for f in * .wav ; do ffmpeg -i " $f " -acodec libmp3lame " ${ f %.wav } .mp3" done I know this loop by heart at this point. If you're doing this regularly, it's worth the setup pain once and never thinking about it again. When it's part of a pipeline If file conversion is happening inside an app — sa
