add SRT file to MP4

If you have a separate SRT file for a respective MP4 video, you can embed subtitles. In just two steps, add hardcoded subtitles to any video—or, generate subtitles and burn them onto the video permanently. 

Burn subtitles into an MP4 video

Make subtitles appear on any video, without the option for the viewer to turn subtitles off or on, for always-on captioning. Once you’ve uploaded your SRT subtitle file, you can edit the text to make sure every word is 100% accurate and in-context.

Customize font, size, and color for subtitles

If you want subtitles on your video, you might as well make them nice to look at. Customize your SRT subtitles by changing the style, size, and color. To make the subtitles pop out even more, you can add animations to make specific words stand out, word-by-word, karaoke style.

Best online video service ever. And a miracle for deaf people.
[Subtitler] is able to autogenerate subtitles for video in almost any language. I'm deaf (or almost deaf, to be correct) and thanks to Kapwing I'm now able understand and react on videos from my friends :)

By the far the most user friendly software to use.
As a housewife at home looking to start a Youtube channel for fun with absolutely zero editing experience, it was so easy for me to teach myself via their YouTube channel. It takes the tediousness out of editing and encourages creativity. As long as Kapwing is around, I will be using their software.

Love this site.
As an English Foreign Language Teacher, this site helps me to quickly subtitle interesting videos that I can use in class. The students love the videos, and the subtitles really help them to learn new vocabulary as well as better understand and follow the video.

Excellent subtitling features
[It] works perfectly for me. Have been using Kapwing for a year or so, and their automatic subtitle tool gets better and better every week, it's rare that I have to correct a word. Keep up the good work!
