If you want one desktop workflow, start with yt-dlp + ffmpeg.
It supports YouTube, TikTok, IG, FB and a lot more, and it’s usually more stable than random web downloaders.
Practical setup that saves time:
– make a small batch script with one command per platform/profile
– use archive mode so it skips files you already grabbed
– standardize output naming (date_platform_creator_title)
– run ffmpeg presets after download so formats stay consistent
If you want a UI instead of CLI, pick a desktop app that’s basically a wrapper around yt-dlp but still gives you batch queue + format presets. That combo matters more than the brand name.
Are you mainly downloading long-form for editing, or short-form for repost/testing?
