Reddit to MP4: How to Convert & Download Reddit Videos

TL;DR: Reddit videos are already MP4 files, but Reddit serves audio and video as separate streams (DASH). That's why downloads often have no sound. To get a proper MP4 with audio: use yt-dlp (free, command line) or RedReap (desktop app, $39/year). Online converters work sometimes but frequently fail on the audio merge.

Reddit videos are already MP4. So what's the problem?

When someone uploads a video to Reddit, Reddit transcodes it into MP4 format. The video file sitting on Reddit's servers is already an MP4. You don't need to "convert" anything.

The problem is how Reddit delivers that video to your browser. Reddit uses a protocol called DASH (Dynamic Adaptive Streaming over HTTP). Instead of serving one file with video and audio combined, Reddit splits them into separate streams:

Your browser fetches both and plays them in sync. But when you try to download the video by grabbing the file URL directly, you typically only get the video stream. No audio. That's not a bug in your download tool. That's how Reddit intentionally structures its video delivery.

Why do Reddit video downloads have no sound?

Because most download tools grab the video stream URL and call it done. The audio stream lives at a different URL, and combining the two into a single MP4 file requires a process called muxing (multiplexing). Muxing requires a tool like ffmpeg to merge the streams into one container.

Free online converters either skip muxing entirely (silent video), attempt it server-side with mixed results, or limit it to short clips because muxing costs server resources. This is why the "no sound" issue is so widespread across every free Reddit downloader.

Method 1: Online converters

RedditSave, RapidSave, Viddit Hit or miss

Paste a Reddit URL, click download, get an MP4. These tools attempt the audio merge server-side.

Works when: The video is short, the site isn't overloaded, and the audio stream is in a standard format.

Fails when: The video is long, the audio is in a format the server can't process, or the site is experiencing downtime. You'll get silent video or an error.

Quality: Usually capped at 720p even when higher resolutions are available on Reddit.

Verdict: Fine for quick, one-off downloads if you don't mind occasional silent output. Not reliable enough to depend on.

Method 2: yt-dlp (free, command line)

yt-dlp + ffmpeg Reliable

yt-dlp is an open-source command-line tool that handles Reddit's DASH streams correctly. It downloads both the video and audio streams, then uses ffmpeg to merge them into a single MP4 locally on your machine.

Install: You need Python, yt-dlp (via pip), and ffmpeg (must be in your system PATH).

Usage:

yt-dlp "https://www.reddit.com/r/subreddit/comments/abc123/post_title/"

That's it. yt-dlp detects the Reddit URL, finds the best quality video and audio streams, downloads both, merges them via ffmpeg, and outputs a single MP4 file.

Pros: Free. Full quality (up to 1080p or whatever Reddit has). Audio always merges correctly. No ads. Works on hundreds of other sites too.

Cons: Command line only. Requires installing three separate tools. No bulk profile downloading without writing scripts.

Method 3: RedReap (desktop app)

RedReap Reliable

A desktop application with a web dashboard. Point it at a Reddit user, subreddit, or individual post, and it downloads all media as properly merged MP4 files (for videos) and original-quality images.

Audio merge: Automatic. Uses ffmpeg under the hood but handles everything without any command-line interaction.

Quality: Full resolution. Grabs the highest available quality from Reddit.

Bulk support: Downloads entire user profiles, subreddit histories, and saved posts. Not limited to one link at a time.

Also handles: RedGifs videos (also delivered as MP4), Reddit galleries, and image posts.

Cost: $39/year.

What about RedGifs to MP4?

RedGifs videos are also MP4 files. Unlike Reddit, RedGifs doesn't use DASH streaming, so the audio and video are in a single file. The challenge with RedGifs is that the video URLs aren't directly exposed in the page source. You need to go through their API to get the actual download link.

yt-dlp handles RedGifs natively. RedReap also supports RedGifs, including bulk profile downloads with thumbnail preview so you can select which videos to save.

Online converters that claim to download RedGifs often break because RedGifs regularly changes their API endpoints and token requirements.

How to get the best quality Reddit MP4

Reddit stores multiple quality levels for each video. When you watch on reddit.com, it auto-selects based on your connection speed. Here's how to ensure you get the highest quality:

  1. yt-dlp: By default, yt-dlp selects the best available quality. No extra flags needed.
  2. Online tools: Most offer a quality dropdown. Select "HD" or "1080p" if available. Many cap at 720p regardless of what they show in the dropdown.
  3. RedReap: Always downloads the highest available resolution by default.

Not all Reddit videos are uploaded in 1080p. If the original upload was 720p, that's the max you'll get from any tool. No tool can upscale beyond what Reddit has.

Download Reddit videos as MP4. With sound. In full HD.

RedReap handles the audio merge automatically. Bulk download entire profiles, subreddits, and saved posts. No command line, no ads.

Frequently asked questions

Why does my Reddit video download have no audio?

Reddit serves audio and video as separate files (DASH streaming). Your download tool only grabbed the video stream. You need a tool that merges both streams, like yt-dlp or RedReap.

Can I download Reddit videos on iPhone or Android?

Online converters work in mobile browsers. Paste the Reddit URL, download the MP4. Quality and audio reliability vary. There's no mobile app for yt-dlp or RedReap.

Is downloading Reddit videos legal?

Downloading publicly posted content for personal use is generally legal. Redistribution or commercial use of copyrighted content is a separate matter. Reddit's terms of service don't explicitly prohibit downloading, but they do prohibit scraping at scale without permission.

What format are Reddit videos in?

MP4 (H.264 video codec, AAC audio codec). Reddit transcodes all uploaded videos into this format. You don't need to convert anything. You just need to merge the separated audio and video streams.

Can I download Reddit videos in 4K?

Reddit caps video uploads at 1080p for most users. Even Reddit Premium users are limited to 1080p. If someone uploaded a 4K video, Reddit transcoded it down. No tool can extract higher quality than what Reddit stores.
