Useful for people who turn recordings, captions, and transcripts into publishable work.
Convert between common file types
Move between SRT, VTT, and TXT without manually reformatting cues or transcript blocks.
Fix subtitle files while you convert
Repair numbering, blank lines, WEBVTT headers, and timestamp punctuation in one pass.
Support subtitle and transcript workflows
Use it for caption prep, transcript cleanup, CMS publishing, and editor handoffs.
Use the SRT, VTT, and TXT converter
Paste a file, choose your target format, and download the result. If you keep the same subtitle format, the tool behaves like a subtitle fixer.
Input
Paste a subtitle file or plain transcript. The converter fixes numbering, headers, whitespace, and timestamp formatting as it converts.
TXT to SRT/VTT uses estimated timing based on words per minute. If you know the final audio length, add it to generate tighter subtitle timing.

A practical shortcut for subtitle and transcript cleanup
A lot of subtitle work is not translation or editing. It is format cleanup. This tool removes that repetitive work so you can stay focused on the content itself.
How it works
Each tool is designed to feel lightweight while still being practical enough for real transcript and subtitle work.
Paste or upload the file
The tool accepts SRT, VTT, and TXT content directly in the browser.
Choose the target format
Select SRT, VTT, or TXT. TXT-to-subtitle conversion can use estimated timing.
Copy or download the result
Use the fixed output in your editor, CMS, YouTube workflow, or archive.
Keep the workflow moving
If you are converting subtitle files, you usually also need transcript cleanup or faster transcript generation.
Transcript Cleaner
