Hardcode SRT to MP4

Permanently burn subtitles into your video so they appear on Instagram, TikTok, and players that don't support closed captions.

Viral Text Presets

Make your captions pop with one click. Use our built-in styles like 'The Beast', 'Neon', or 'Hormozi' to increase viewer retention.

100% Free & Private

Unlike other tools that charge for 'burning' captions or add watermarks, we process everything locally in your browser for free.

Make Your Video Stand Out

80% of videos on social media are watched on mute. If you don't have captions, you're losing views. FastVideoCutter allows you to upload an existing .SRT file and "burn" it into the video permanently. Customize the look to match your brand style instantly.

How to add subtitles to video online?

  1. 1

    Click "Start Editing" and upload your video.

  2. 2

    Go to the Text tab and click "Import Subtitles (.srt)".

  3. 3

    Your subtitles will appear on the timeline. Select them to customize styles:

    • Change font, color, and background.
    • Use Presets like "The Beast" or "Neon" for quick styling.
    • Drag clips on the timeline to adjust timing if needed.

No Watermark

Most online subtitle tools (like Veed or Kapwing) add a huge watermark unless you pay. FastVideoCutter is completely watermark-free.

Privacy First

Since we process the video in your browser using WebAssembly, your private videos and subtitle files never touch our servers.
