Subtitle & caption converter
Convert your caption or subtitle files to different formats online. A lot of projects need an SRT converting into another format to work with different software — so convert SRT, VTT and SBV files to SRT, VTT, SBV, plain text or CSV, and clean up or shift their timing at the same time. It all runs in your browser; nothing is uploaded.
Choose your file
Select any .srt, .vtt or .sbv subtitle file. It's read straight in your browser — nothing is uploaded.
Pick a format & clean up
Choose the format you need, then tick any clean-up options to repair and tidy the file as you convert.
Download or copy
Grab the converted file instantly, or copy the output straight to your clipboard.
Your converted subtitles will appear here.
Choose a file to get started.
Supported formats
SubRip — the universal default, used by Premiere, Resolve and most players.
WebVTT — the standard for web video, HTML5 and YouTube.
YouTube / SubViewer — YouTube's own caption format.
Timed Text Markup — the XML caption format used by many broadcast and post-production tools.
Plain text — a clean transcript with the timecodes stripped out.
Spreadsheet — start, end, duration and text in columns for review or translation.
Also useful: the subtitle reading speed checker flags any cue that's too fast to read.
It repairs, not just converts
Tick any of these as you convert and the tool cleans the file up on the way out — fixing the small errors that trip up editing software.
Remove empty subtitles
Strip out any cue that has no text — a common cause of errors in other software.
Trim extra whitespace
Collapse double spaces and trim stray whitespace from the start and end of lines.
Fix overlapping cues
Trim each subtitle's end to the next one's start so timings never collide.
Merge identical subtitles
Combine repeated back-to-back cues into one, tidying up roll-up style captions.
Shift all timings
Move every subtitle by the same offset to fix a file that's uniformly early or late — no video needed.
Clean numbering & formatting
Re-numbering and technical reformatting are handled automatically on every export.
Frequently asked questions
You can import SubRip (.srt), WebVTT (.vtt) and YouTube (.sbv) files, and export to SRT, VTT, SBV, TTML (Timed Text), plain text (.txt) or spreadsheet (.csv). Just pick your target format and download.
