Convert SRT to TXT with the SubtoVTT API

Convert SRT to TXT programmatically with one HTTP request. The SRT to TXT API strips the timestamps and cue numbers and returns the plain transcript — nothing but the dialogue text.

It's the conversion for transcripts, archives, search indexes, and any place that wants captions without timing. One credit per conversion, 100 free credits to start.

Why convert SRT to TXT with an API

• Transcripts: clean dialogue text for notes or publishing.
• Search: index subtitle text without timing noise.
• Automate: extract plain text from caption files at scale.

Convert with cURL

curl -X POST https://api.example.com/api/v1/convert \
  -H "Authorization: Bearer your_api_key" \
  -F "[email protected]" \
  -F "from=srt" \
  -F "to=txt" \
  -o transcript.txt

Compact example — Ruby

require "net/http"
require "uri"

url = URI("https://api.example.com/api/v1/convert")
boundary = "----SubtoVTT#{rand(1_000_000)}"
content = File.binread("movie.srt")
body = +"--#{boundary}\r\n"
body << "Content-Disposition: form-data; name=\"file\"; filename=\"movie.srt\"\r\n\r\n"
body << content << "\r\n"
body << "--#{boundary}\r\nContent-Disposition: form-data; name=\"from\"\r\n\r\nsrt\r\n"
body << "--#{boundary}\r\nContent-Disposition: form-data; name=\"to\"\r\n\r\ntxt\r\n"
body << "--#{boundary}--\r\n"

req = Net::HTTP::Post.new(url)
req["Authorization"] = "Bearer #{ENV['SUBTOVTT_API_KEY']}"
req["Content-Type"] = "multipart/form-data; boundary=#{boundary}"
req.body = body
res = Net::HTTP.start(url.host, url.port, use_ssl: true) { |http| http.request(req) }
File.binwrite("transcript.txt", res.body)

Format notes

Tip: keep the original SRT — timing is lost in TXT output, so this is a one-way conversion.

FAQ

Is SRT to TXT one-way? Yes. TXT has no timing, so you can't convert it back to a timed format.

Can I clean the text while converting? Yes — combine with clean_sdh (strip [sound]/(applause)) or fix_all_caps for a readable transcript in one call.
