How to merge subtitles with any video permanently (6 ways) (2025)

These step-by-step tutorials will show you how to merge subtitles with any video permanently. This works for MP4, MKV, AVI, and other video files.

Some devices, like the Sony PlayStation 3, 4, and 5, and some TVs don't support SRT subtitle files. If you want to play a video or movie with subtitles on devices that don't support the SRT subtitle format, you must hardcode the SRT subtitle file into the video file.

MKVToolNix is a set of tools to create, edit, and inspect MKV video files on Windows and Linux. You can also use MKVToolNix to merge MKV, MP4, and AVI video files with SRT subtitle files. For Windows, MKVToolNix is available as an installer and as a portable 7zip archive. You can download MKVToolNix for Windows here.

Note: If you've downloaded the portable version of MKVToolNix, you will need to unzip the .7z file first. You can use 7-Zip for this.

Make sure the subtitle file has the same filename as the video file (e.g., Movie.mp4 and Movie.srt).
Open MKVToolNix (mkvtoolnix-gui.exe or mkvtoolnix-gui).
