Convert Subtitles

Convert Subtitles Between SRT and WebVTT

Paste your captions or drop a .srt or .vtt file, pick the format you need, and get a clean, correctly-formatted result you can copy or download. The converter reads both directions — SubRip to WebVTT and back — and rewrites every timestamp to each format's rules automatically: SRT's 00:00:01,000 commas, WebVTT's 00:00:01.000 dots, and the required WEBVTT header.

Out of sync with your video? Shift every cue by a set number of seconds — positive to delay, negative to pull earlier, decimals allowed — so the whole track lines up in one pass. WebVTT cue identifiers and cue settings are preserved on the way through, and an optional switch strips inline tags like <i> and <v Speaker> when you just need plain text.

Unlike most online subtitle converters, this one runs entirely in your browser. Caption files often carry unreleased scripts, client names, or private video content — here they are parsed as plain text on your own device and never uploaded to a server.

Common Use Cases

• Web video players: HTML5 <track> and most browser players need WebVTT — convert an .srt export from your editor in one step.
• Editing software: Turn a .vtt download from YouTube or a transcription service back into .srt for Premiere, DaVinci Resolve, or CapCut.
• Fixing sync: Nudge subtitles that run a second or two early or late until they match the audio.
• Cleaning captions: Strip italics, bold, and voice tags to produce a plain, portable text track.
• Standardizing files: Bring a mixed set of .srt and .vtt files into one consistent format before delivery.
• Accessibility work: Produce WebVTT captions for compliant, screen-reader-friendly video embeds.

Privacy: Everything runs entirely in your browser using plain-text parsing — your subtitle files never leave your device, and there is no upload, signup, or usage limit.
