Local Video Processing
Your browser decodes, styles, and renders every video frame locally. No video data reaches our servers.
Drop in a video and get word-timed captions in seconds. Retime any word to the millisecond, pick from 30 styles, then export a captioned MP4 or an SRT file. Built for creators, educators, and video editors.
Live demo, no signup needed.
Most online subtitle tools upload your entire video to their servers. SnapSubtitles sends the audio track, never the video.
Your browser decodes, styles, and renders every video frame locally. No video data reaches our servers.
The editor extracts a compressed audio track and sends only that to the speech-to-text service. Your visual content stays private.
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.
You go from raw footage to a subtitled video in four steps. Nothing to install, and your video never goes to a server.
Drop your video into the browser editor, or click to browse. MP4, WebM, and MOV all work. Video frames stay on your device.
We transcribe your audio and return word-level timing. Auto-detection covers dozens of languages.
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.
Download a captioned MP4 rendered locally in Chrome, Edge, or Safari, or export SRT and VTT subtitle files. Downloads use video minutes and never carry a watermark.

Captions keep viewers reading when they watch on mute, and they open your videos to people who do not speak your language natively. Export a captioned MP4, or download an SRT for YouTube Studio.
Make lectures and tutorials accessible. Word-timed captions help deaf and hard-of-hearing students, and they help non-native speakers follow along.
Caption ads, Reels, and TikTok clips. The Bold and Karaoke styles are built for feeds that autoplay on mute.
