What is inside an SRT file

An SRT source stores subtitles with timing: sequential number, timecode range, sub text, and blank line separators. Repeats for every entry.

Numbers, timecodes, and blanks make up ~40% of content. SRT files often contain HTML tags invisible in players but clutter when pasted into documents.

The SRT Cleaner removes all of these elements automatically. What remains is clean, readable text ready for editing, publishing, or repurposing.

Supported Subtitle File Formats

Works with standard .srt files and plain text with SRT content. Processes numbering, timecodes, subtitle blocks, and blank lines.

Handles HTML tags, positioning tags, speaker labels, and SDH descriptions. All stripped during cleaning.

Formats: .srt, .txt with SRT content, raw pasted SRT text.
