Subtitle Convert

Subtitle Convert is a free browser-based subtitle utility for creators, translators, editors, students, and media teams. Batch-convert SMI, SRT, VTT, ASS, and Whisper JSON subtitle files without installing software or creating an account. Upload multiple files, choose the desired output format, and download the converted results together in a ZIP archive. When captions exist only as screenshots, the optional OCR workflow can extract text from caption images in the browser. The tool is designed for quick, privacy-friendly work on local files and supports common subtitle formats for video editing, localization, accessibility, and bilingual learning. No signup is required and the core workflow is free.

What problem it solves
