Add Subtitles to Video Online

Add subtitles to your videos automatically with AI. SubVidos helps creators generate accurate and stylish captions in seconds. Upload your video, generate subtitles, choose a subtitle style and export your video ready for TikTok, YouTube or Instagram.

Works with MP4, MOV, M4V and WebM. Automatic language detection in 90+ languages.

How it works

A focused three-step flow that lets you go from raw video to finished subtitles without complex timelines or editors.

  1. Step 1 — Upload your video

    Drag and drop your MP4, MOV, M4V or WebM file. SubVidos automatically prepares it for subtitle generation, even if it was recorded on a phone.

  2. Step 2 — AI generates subtitles automatically

    Our speech recognition engine detects the spoken language and generates precise subtitles with proper timing, punctuation and casing.

  3. Step 3 — Choose subtitle style and export

    Pick one of the ready-made subtitle templates and export either a video with burned-in subtitles or a clean SRT file for platforms like YouTube.

FAQ

What video formats are supported?

SubVidos supports MP4, MOV, M4V and WebM. Phone recordings with variable frame rate or rotation metadata are normalised automatically so subtitles stay in sync.

Can I export subtitles as SRT?

Yes. After generation you can download the SRT file separately or export a video with subtitles permanently burned into the frame.

Can I add subtitles for TikTok, Instagram or YouTube?

Absolutely. SubVidos is optimised for short-form vertical content as well as longer YouTube videos. You can reuse the same subtitles across TikTok, Instagram Reels, YouTube Shorts and the main YouTube player.

Do I need a subscription?

No. You can try SubVidos for free on short clips, then purchase credits only for the minutes you actually process. There are no recurring fees or long-term contracts.
