Local Video Processing
Video frames are decoded, styled, and rendered entirely inside your browser. No video data is ever uploaded to our servers.

Your Video Stays on Your Device
Most subtitle generators upload your entire video to a remote server. SnapSubtitles works differently.
Audio-Only Transcription
The editor extracts a compressed audio track and sends only that to the speech-to-text service. Your visual content stays private.
No Cloud Storage
There is no server-side file storage. When you close the tab, the video is gone from memory. Captions are saved locally in your browser until you clear them.
How to Create Subtitles in 4 Steps
This video caption generator takes you from raw footage to a subtitled video in four steps. No software to install, no files to upload to a server.
Upload
Drop your video into the browser editor or click to browse. Supports MP4, WebM, and MOV files. Video frames stay on your device.
Transcribe
The AI subtitle generator transcribes your audio with word-level timing. Auto-detection covers dozens of languages.
Edit
Fix any word, adjust start and end times to the millisecond, split or merge caption cues, and switch between 30+ built-in styles. Changes appear instantly on the video preview.
Export
Download a captioned MP4 rendered locally in Chrome or Edge, or export SRT and VTT subtitle files. Free exports include a small watermark; paid plans remove it.
