Save Reddit videos with sound as MP4 files. Free, no app needed, works on all devices.
Download any Reddit video with audio to your device.
Find a Reddit video post, tap Share, and select "Copy Link". Works with reddit.com and old.reddit.com URLs.
01Paste the Reddit post URL into the download field above. GrabMP4 automatically merges the video and audio tracks.
02Click Download and the video (with sound) saves to your device as a single MP4 file.
03Reddit stores video and audio as separate streams — the video file has no sound, and the audio is in a separate DASH file. This is why saving a Reddit video directly from the browser results in a silent video. Reddit also doesn't provide a download button on its platform.
GrabMP4 solves this by automatically detecting and merging both the video and audio streams into a single MP4 file with full sound. This process happens on our servers in seconds. No technical knowledge needed — just paste the Reddit post URL.
Reddit has over 1.7 billion monthly visits (source: SimilarWeb), and video content is growing rapidly across subreddits. GrabMP4 supports all Reddit video formats and works on any device — iPhone, Android, desktop. You can also download from YouTube, TikTok, Instagram, Twitter/X, and Threads.
