SubVid review
A free local-first caption tool with strong editing and privacy, but limited export options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SubVid is a free, browser-based tool for generating, editing, translating, and exporting subtitles from video and audio files. It is aimed at individuals and teams that want a simple caption workflow with local processing. AI speech transcription uses Whisper, while subtitle translation uses NLLB-200. Users can edit subtitle text and timing, adjust caption appearance, and export finished captions without sending uploaded media to a backend.
The main strength is its privacy-focused browser workflow. Local processing keeps video and audio files in the browser rather than uploading them, which suits users handling sensitive media or preferring a local-first tool. SubVid also covers the core captioning sequence in one place: transcription, translation, timeline editing, styling, and output. Styling controls include font, color, background, outline, and position, giving users direct control over how captions appear in the final video.
SubVid is free, with no paid tiers described, but its output range is narrow. Subtitle-file export is limited to SRT, while video output is an MP4 with captions burned in. The product also has no integrations, so it is better suited to standalone browser workflows than connected production pipelines. Its license permits noncommercial use only, which matters for commercial teams. Choose SubVid for local, straightforward caption creation and translation; choose an alternative when you need broader subtitle formats, integrations, or commercial licensing.
