Getting started

Subtitle Convert is a set of 25 free tools for working with subtitle files. Everything runs in your browser — no accounts, no uploads, no cost.

Basic workflow

1. Open the tool directory.
2. Pick the tool you need (search by keyword if you know what you want).
3. Paste your subtitle text or load a file.
4. Click the action button (Convert, Shift, Validate, etc.).
5. Copy the output or download it.

Privacy basics

Your subtitle file never leaves your device. All processing happens in the browser using JavaScript. There is no backend service. This means:

• You do not need to trust us with your file.
• The site continues to work offline once loaded.
• You can use it on any computer, phone or tablet.
