Caption Maker — Clideo

Online Subtitle Adder

The tool is completely online which means that you don't need to download any software or app to your device. It's both faster and secure!

Several Options

You can decide how to add subtitles to your video: manually or with an SRT subtitle file. In any case, you can edit them then.

Edit Subtitle Font

We don't limit you! Select a font, its size, align the text. Also, choose its color and background to make the subs look brighter and seen on both black and white.

Free and Online Video Caption Maker

Have you ever seen auto-generated subtitles on YouTube? Usually, they are no more than illegible nonsense, which has nothing in common with the original text.

Nothing can compare with elaborated and manually-created subtitles. To add them, you need a free online caption maker, and luckily, we have one!

Our tool has many merits, but let’s just mention a couple of them:

Safety. Only you have access to your project while you are working on it. If registered, you can also manage your videos on your profile page. Duplicate, delete, and edit them.
Online. To use our tool, you don’t have to download and install any caption maker software or app, put up with endless advertisements, and waste the precious memory of your smartphone.

The best video editor. I've already tried out a lot of video editors, but this is the best one. It has everything in there, unlike others that need a lot of other websites to do different things. Thank you so much.
