SRT, SMI, VTT, ASS, SUB, TXT
This browser-based tool converts and edits SRT, SMI, VTT, ASS, SUB, and TXT subtitle files. In one screen, you can change formats and encodings, edit subtitle text, correct timing, validate errors, search and replace, clean up content, and batch-convert up to 20 files.
Upload a Subtitle File
On the Convert tab, select a supported subtitle file or drag it into the upload area.
Choose the Output Format and Options
Choose the target subtitle format and encoding, then optionally enable removal of HTML tags, empty lines, or duplicate lines.
Review Content and Timing
Use the Edit, Sync, and Tools tabs to revise subtitle text, adjust offsets or frame rates, and validate for errors.
Convert and Download
Convert and download the result. To process multiple files together, use the Batch Convert tab for up to 20 files.
You can open SRT, SMI, VTT, ASS, SUB, and TXT files and convert them to any other supported format. Format-specific effects or styles may be simplified depending on the capabilities of the target format.
Reload the source file with the correct encoding, then choose UTF-8 or EUC-KR for download based on what your playback environment supports.
On the Sync tab, apply a fixed offset to every subtitle or correct the full timeline by setting a timing scale and source and target frame rates.
Add up to 20 files on the Batch Convert tab, convert them to the same target format and encoding, and download them together.
Use subtitle validation on the Tools tab to find overlapping timings, empty text, long lines, and other issues, then clean up items that can be fixed automatically.
