Let's face it: In this day and age, the internet is ephemeral. Anything anybody posts might be here one day, and gone the next. Websites take down or move their images and videos, posts get hidden or removed, and their content is lost. Even more so on Reddit, where accounts are constantly springing into existence - and then vanishing as quickly without a trace. How's anybody supposed to keep their cherished cat picture collection around with all this change? Well fear not, my data-hoarding friend, because Reddit Media Downloader is here for you!
Reddit Media Downloader is a program built to scan Comments & Submissions from multiple sources on Reddit, and download any media they contain or link to. It can handle scanning posts from your personal Upvoted/Saved lists, subreddits of your choice, user-curated multireddits, and more! When it finds a Comment or Submission from wherever you specify, it will parse the text and links within to find any media linked to. It then uses multiple downloaders to save this media locally onto your disk.
RMD comes equipped with a suite of options to let it scan just about anywhere you can find media on Reddit. Coupled with its powerful baked-in Filter options to let you specify exactly what type of posts and comments you're looking for ("I only want Submissions with 'Unicorn' in the title, and no less than 1000 upvotes!"), RMD makes automatically saving things a simple process. Built in Python and runnable headless (without a GUI) or as its own server, you can launch this program anywhere - and it's built from the ground-up to make automation a breeze.
If you hit any links which RMD does not support, find anything broken, need assistance, or just want to suggest new features, please open a new request here.
RMD is currently under a large-scale rewrite in a new language, which will greatly expand its capabilities. If you don't see much recent activity in the master branch, or in the bug reports, it's probably because the rewrite already fixes the problems or adds the requested features. In the meantime, the current release of RMD is considered extremely stable, and should work exactly as expected.
