Upload a messy SRT or VTT file and remove HTML tags, ASS/SSA styling, VTT metadata and empty lines without changing the timestamps.
Your subtitles are cleaned locally in your browser. No upload required.
Messy subtitles with HTML formatting, font colors, ASS/SSA styling or WebVTT metadata can cause problems in video players, social-media uploads and editing software. The SRT & VTT Cleaner strips distracting code and creates a clean, compatible subtitle file.
Upload an SRT or VTT file, choose the cleanup options you need and download the cleaned version. Everything runs locally in your browser. Your file is not uploaded to a server.
Typical broken SRT files contain HTML tags, font colors, italic or bold formatting and non-breaking spaces. The Cleaner removes visible clutter while leaving numbering and timestamps untouched.

This line still has tags.Some subtitle files contain ASS or SSA styling even though they are saved as SRT. These tags control position, alignment, color or animations. Many platforms display them as plain text or reject the file.
{\an8}Show text at the top
{\pos(640,80)}Positioned subtitle line
{\c&H00FFFF&}Colored subtitle textWhen the ASS/SSA option is enabled, the Cleaner removes these curly-brace styling tags from the visible subtitle text. The timestamps stay unchanged.
WebVTT files can contain extra metadata that is useful in browsers but distracting in plain subtitle workflows. The Cleaner can remove NOTE comments, STYLE CSS blocks and REGION definitions without deleting the actual cue times or subtitle text.

Privacy comes first. The entire cleanup process runs through JavaScript in your browser. Your SRT or VTT files never leave your device, which means no upload wait time and no risk of subtitle data being exposed.
Besides styling tags, the Cleaner also detects empty subtitle blocks: blocks that contain timestamps but no visible text. Such blocks can confuse players and editing tools and can optionally be removed completely.
Cleaning removes visible styling code, but it does not check every structural SRT problem. If your file still has broken numbering, overlapping timestamps or empty blocks, run it through the SRT Validator afterwards.
