Add Subtitles to Video Free

Add subtitles to a video in one upload. AI transcribes the speech and burns the captions into the picture, so they show on every player and platform, sound on or off. You also get the editable .srt file. Free, no account, no watermark. Works on MP4, MOV, MKV, WebM up to 2GB and 30 minutes.

VidClean adds subtitles to video for free: it transcribes the speech with a hybrid Parakeet-TDT and Whisper engine, burns the captions into the video, and also gives you the editable .srt file. No account is required and there is no watermark. Files are processed server-side and automatically deleted within 1 hour.

How It Works

Upload your video

MP4, MOV, MKV, or WebM up to 2GB and 30 minutes. Drag and drop or click to browse. Pick the spoken language first, or leave it on auto-detect.

AI transcribes and burns the captions

A hybrid Parakeet-TDT and Whisper engine converts the speech to timed subtitles, then the captions are rendered permanently into the video frames: clean white text with a black outline at the bottom. The same engine powers our transcription tool if you only need the text.

Download the captioned MP4 and the .srt

The primary download is your video with the subtitles burned in. You also get the .srt file in case you want to edit the text or restyle it elsewhere. Just want the text without the video? Use the transcriber instead, it handles up to 90 minutes. Want to see what runs behind the scenes? Learn how VidClean works technically.

Who uses this

Creators posting to TikTok, Reels, and Shorts where most viewers watch with the sound off. Teachers and course makers captioning lessons. Anyone making videos accessible without learning a subtitle editor or paying for a captioning subscription.

Drop your video, get it back with captions everyone can read.

Frequently Asked Questions

Everything you need to know about adding subtitles with VidClean.

Can I add subtitles to a video for free without an account? expand_more

VidClean's subtitle generator is completely free, no account, no watermark, and no trial limits. Your files are deleted 1 hour after processing.

Are the subtitles burned into the video or a separate file? expand_more

The speech is transcribed with a hybrid Parakeet-TDT and Whisper engine, then the captions are burned directly into the video frames (hardcoded). They show up on every player and platform with no settings to enable. You also get the .srt file.

Can I edit the subtitle text or style? expand_more

Yes. Everyone can preview every caption style for free in the live preview, including all 10 fonts. Burning a custom style into your video (9 Pro fonts plus color, position, size, and background) is a Pro feature; free downloads use the standard DejaVu Sans captions.

What languages can subtitles be generated in? expand_more

English, Spanish, Portuguese, French, German, Italian, Dutch, and Russian, with automatic detection. More languages are coming; the current list is limited by the subtitle font's character coverage.

What video formats can I add subtitles to? expand_more

Video files (MP4, MOV, MKV, WebM) up to 2GB and up to 30 minutes long. The output is always an MP4 with the captions burned in.

Why are burned-in subtitles limited to 30 minutes? expand_more

Burning subtitles requires re-encoding the whole video, which takes roughly as long as the video itself on our servers. The 30 minute cap keeps processing times reasonable for everyone. Need just the text of a longer recording? The transcriber handles up to 90 minutes.

Is my video private and deleted afterward? expand_more

Yes. Files are automatically deleted from our servers 1 hour after processing.
