Online Tools for Subtitle Conversion, Shifting, Cleaning & Translation
Conversion
Subtitle One currently supports converting text-based subtitle files such as ASS, VTT, SBV, and image-based subtitle files such as PGS SUP and VobSub IDX/SUB into SRT or VTT.
The entire conversion process, including subpicture conversion, takes place locally in your browser with no files or content ever sent to our server. This ensures your complete privacy.
Adjustment
The Adjustment page allows you to apply timing shifts to your subtitles and/or clean up your subtitle files. Supported formats: SRT, ASS, SBV, WebVTT. More will be added in the future.
Three shift modes are available: simple, partial and linear shifts. For Adjustment, none of your files or content will be sent to our server. All adjustments take place locally in your browser.
Translation
Here you can translate your subtitles from any language to more than 100 languages using Google Translate™.
While machine-translated subtitles are not as accurate as human-translated ones, they are still very usable in helping the audience understand the dialogues.
