Frequently asked
Why convert IMSC to SRT?+
Internet Media Subtitles and Captions is the modern W3C streaming profile of TTML used by Netflix, Apple TV, and most streaming services. SubRip Subtitle is built for delivery to almost any video editor or upload form. Converting lets you take a file produced for one workflow and use it in the other without re-typing or re-timing anything.
Is timing preserved exactly?+
Yes. The converter only re-encodes the file structure — start and end times round-trip to within one millisecond.
Does any styling survive the conversion?+
Neither format carries styling, so there's nothing to lose. The text and timing transfer exactly.
Does this run on a server?+
No. The conversion is pure JavaScript running in your browser — files never upload anywhere. Works offline once the page is loaded.
