About Subtitle Cleaner & Validator

Use Subtitle Cleaner & Validator when you need a focused result without installing a separate desktop application. Validate SRT or WebVTT cues, normalize spacing and report ordering or timestamp errors. The result changes when the source data or selected options change, so it is easy to run a second comparison.

For a typical workflow, use it to make a shorter or more compatible copy for a presentation, website or social channel. Start with a representative input, inspect the first result, then adjust one setting at a time if you need a different outcome.

Processing stays in the browser where the individual feature supports it. Live public checks use a protected, rate-limited site endpoint; avoid unnecessary sensitive data.
