Subtitle tools for common file jobs
Start with the change you need to make. Subtitle Tools groups utilities for changing, combining, dividing, and checking subtitle files. Convert Tools handles format changes, Edit Tools handles direct edits, Merge Tools combines files, Split Tools divides them, and Validate Tools checks subtitles against quality-control rules.
Convert and edit subtitle files
- Convert Tools changes the format of subtitle files. Use it when a subtitle file needs to move into another format.
- Edit Tools makes direct changes to a subtitle file. Its child tools cover subtitle frame-rate conversion, subtitle styling, and timestamp shifting. Use this group for timing, appearance, and other direct edits.
Merge and split subtitle files
- Merge Tools combines subtitle files into one file. Choose it when separate subtitle parts need to become a single file.
- Split Tools divides a subtitle file. Choose it when one file needs to be separated into smaller subtitle files.
Check subtitle files against quality rules
- Validate Tools checks SRT and WebVTT subtitles against quality-control rules. Pick it when the task is finding issues rather than changing a file's format, timing, style, or structure.
Typical subtitle jobs
For a format change, open Convert Tools. The other groups change different parts of a subtitle file, so they are not the starting point for conversion.
Edit Tools covers timing work after a frame-rate change, including subtitle frame-rate conversion and timestamp shifting. The group also includes subtitle style changes.
When subtitles are split across files, Merge Tools combines them into one file. When one file needs to become several smaller files, use Split Tools.
For a quality check, use Validate Tools. It checks SRT and WebVTT subtitles against quality-control rules. Use Convert Tools, Edit Tools, Merge Tools, or Split Tools when the file itself needs a format, timing, style, or structure change.
How to choose between subtitle tools
Match the group to the file change: format conversion in Convert Tools, direct text, timing, or style changes in Edit Tools, combining in Merge Tools, dividing in Split Tools, and rule-based checking in Validate Tools. For work outside subtitles, open Media Tools, which groups utilities for images, video, audio, subtitles, and fonts.
The Convert Tools, Edit Tools, Merge Tools, and Split Tools descriptions say that processing happens locally in the browser with no upload. The parent Media Tools page also says that files are not uploaded. Validate Tools is described as a checker for SRT and WebVTT subtitles.
