How to Save Reddit Videos with Audio: 3 Simple Methods

The single most common complaint among Reddit users sharing media is that downloaded videos often come with no sound.

Saving Reddit videos with audio is actually very simple once you know how to handle the separate streams. In this guide, we will cover the three most reliable methods for 2026, including an advanced look at local file combining.

1. The Technical Split: Why Reddit Videos Are Silent

When users upload videos directly to Reddit, the platform splits the upload into separate video-only and audio-only files using the MPEG-DASH streaming protocol. This allows Reddit's player to dynamically adjust video resolution based on your network connection speed while keeping the audio stream continuous.

If you try to download a video directly by right-clicking or using standard download helpers, you only retrieve the active visual track (e.g. DASH_720.mp4), leaving the audio file (DASH_audio.mp4) behind. To get a complete video, you need a method that merges these tracks. For more information, read our comprehensive study on Why Reddit Videos Have No Sound.

2. Method 1: RDT Video Downloader (Easiest Web Solution)

The most popular and recommended method to save Reddit videos with audio is to use a web-based converter that automatically merges the files on its servers.

Step-by-Step Instructions:

1. Copy the URL: Open the Reddit post and copy the URL from your address bar or share sheet.
2. Paste and Parse: Visit RDT Video Downloader, paste the link, and click Download Now.
3. Download: Choose your resolution (up to 1080p). The downloader combines the separate DASH_audio and DASH_video streams on our server and provides a single, high-quality MP4 file.

This tool is optimized for all browsers and devices. If you are using a mobile device, you can read our specialized guides:

3. Method 2: Desktop Browser Extensions (Chrome & Firefox)

For desktop users who frequently download Reddit media, installing a web browser extension can save time. These extensions inject a "Download" button directly under Reddit posts.

Popular Extensions:

• RedditSave Extension: Adds a simple button next to the standard Reddit share options.
• Video Downloader Professional: A general media downloader that detects DASH streams on the active tab.

How to Use:

1. Search for a reputable downloader extension in the Chrome Web Store or Firefox Add-ons Manager.
2. Click Add to Browser and accept permissions.
3. Open Reddit. You will see a new "Download" button on video posts. Click it to save the video with sound.

[!WARNING] Be cautious with third-party extensions. Some extensions may track your browsing behavior, inject affiliate ads, or consume excess memory. Always check reviews and user feedback before installation.

4. Method 3: Native Apps and Screen Recording (Mobile OS)

If you are on a mobile device and cannot access external websites, you can use built-in system tools as a temporary fallback.

iOS & Android Screen Recording

Both iOS and Android have native screen recorders.

• On iPhone: Open your Control Center, tap the Screen Recording icon (a circular dot), play the Reddit video in full-screen with sound enabled, and stop recording when finished.
• On Android: Swipe down twice to access Quick Settings, tap Screen Record, select "Media Sounds" as the audio source, and record the playback.

Disadvantages:

• Quality Loss: Re-encoding a playing video results in visible pixelation and lower audio bitrates.
• UI Clutter: Mobile notification banners, volume sliders, and play buttons will be captured in the output file.
• Manual Editing: You must crop the start and end of the recording in your photo gallery.

5. Advanced: Muxing Video and Audio Locally with FFmpeg

If you are concerned about privacy or want to merge high-resolution streams (like 4K) locally without sending links to third-party servers, you can perform the multiplexing (muxing) process on your own computer.

To do this, you will need FFmpeg, a powerful, open-source command-line tool for handling multimedia files.

Steps:

1. Extract the Streams: Inspect the network tab in your browser's Developer Tools (F12) while playing a Reddit video. Locate the URLs for the video stream (usually contains DASH_1080 or DASH_720) and the audio stream (contains DASH_audio).
2. Download Both Files: Save both files to your computer as video.mp4 and audio.mp4.
3. Run FFmpeg: Open your command line (terminal or command prompt) in the directory containing the files and execute the following command:

ffmpeg -i video.mp4 -i audio.mp4 -c:v copy -c:a aac -map 0:v:0 -map 1:a:0 output.mp4

Command breakdown:

• -i video.mp4 -i audio.mp4: Specifies the two input files.
• -c:v copy: Directs FFmpeg to copy the video stream directly without re-encoding, preserving the original quality.
• -c:a aac: Encodes the audio stream into AAC format for maximum player compatibility.
• -map 0:v:0 -map 1:a:0: Maps the first input file to the video track and the second input file to the audio track.

The output file, output.mp4, will be a high-quality video with the sound perfectly synchronized.

6. Summary and Best Practices Checklist

To ensure your downloaded Reddit videos play properly with full audio, use this quick checklist:

• Check the mute icon: Ensure the video actually has sound on Reddit before downloading. Some uploads are muted by default or are uploaded as silent animated GIFs.
• Avoid screen recording: Use cloud downloaders or extensions first to preserve 1080p HD quality and avoid UI clutter.
• Use VLC Media Player: If your downloaded video is silent, try playing it in VLC. Some default system players (like Windows Media Player or quick iOS previews) struggle to parse AAC audio tracks inside specific MP4 containers.
• Clear player cache: If videos buffer, check our troubleshooting guide on Reddit Video Player Fixes.
