How do I remove website URLs or credits from subtitle files in bulk?

Drop all your subtitle files into the tool. Enable the Remove Specific Text option and enter the phrase you want deleted, such as a URL or credit line. Click Process and download a ZIP containing all cleaned subtitle files instantly.

How do I fix subtitles that are out of sync?

Use the Shift Time feature. If subtitles appear too early, enter a positive value such as +2000 milliseconds to push all timestamps forward by 2 seconds. If subtitles start correctly but gradually drift over time, use the Convert Framerate tool to correct the playback speed mismatch between the subtitle file and the video.

Are my subtitle files uploaded to a server when I process them?

No. All processing runs entirely in your browser using JavaScript. Whether you process one file or hundreds, your subtitle content is never transmitted to or stored by any server.

Can I convert SRT subtitle files to VTT format?

Yes. The tool supports SRT to VTT and VTT to SRT conversion as part of the batch processing pipeline. Select the output format before processing and all converted files will be included in the downloaded ZIP.

Frequently Asked Questions

Can I convert ASS/SSA anime subtitles to SRT?

Yes. The converter can read ASS and SSA dialogue lines, strip advanced styling, and export a cleaner SRT or VTT file for standard players.

How does framerate (FPS) conversion work?

If your video and subtitle file were created for different framerates, subtitles gradually drift out of sync. FPS conversion rescales the timestamps across the full file so they align with the video timing.
