Converting a .itt file to .vtt extracts the document's content from its office package into a portable form. An .itt file is an iTunes Timed Text document: a constrained TTML profile that Apple defined for subtitle delivery to the iTunes Store and Apple TV. Its defining trait is timing — cues are addressed in SMPTE timecode (HH:MM:SS:FF) against a frame rate declared in the document header.
A .vtt file is a WebVTT caption document: a WEBVTT header followed by timed cues for HTML5 video and audio. It is the web-native caption format browsers expect for the track element. For this route the practical draw is first-class support in modern browsers and richer cue settings than SubRip — balanced against some legacy desktop players prefer .srt and mishandle WebVTT settings, which is worth knowing before you commit a large batch.
Why convert ITT to VTT?
The practical trigger for this conversion is usually a mismatch: with .itt, frame timecodes are meaningless without the declared frame rate, so a mis-set header shifts every cue. Switching to .vtt buys you first-class support in modern browsers, which is why it is the better fit for captioning HTML5 video with the track element. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
ITT vs VTT at a glance
| Aspect | iTunes Timed Text (.itt) | WebVTT subtitles (.vtt) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | timing is frame-accurate: begin and end are HH:MM:SS:FF timecodes resolved against ttp:frameRate, optionally scaled by ttp:frameRateMultiplier for drop-frame rates such as 23.976 | files begin with WEBVTT and optional metadata headers before the first blank line |
| Strongest at | delivering subtitles to Apple's ingest specifications | captioning HTML5 video with the track element |
| Weak spot | frame timecodes are meaningless without the declared frame rate, so a mis-set header shifts every cue | some legacy desktop players prefer .srt and mishandle WebVTT settings |
Pick VTT as the output
Select .vtt in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if VTT is selectable, the route is real and validated.
Convert on your device
Press Convert. The package is unzipped in memory and its XML content parsed locally; nothing is uploaded.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid VTT file. Outputs keep the original filename with the .vtt extension.
ITT to VTT questions, answered
Will converting ITT to VTT lose quality?
There is no visual quality to lose — itt is text-oriented and vtt is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert ITT files here?
Yes — the .itt file is processed inside your browser tab and never uploaded. The package is unzipped in memory and its XML content parsed locally; nothing is uploaded. Close the tab and the file is gone from memory.
Where will the VTT file work?
Chrome, Firefox, Safari, and Edge render .vtt through HTML track elements. Professional editors and many downloadable players also import it, though SubRip remains more common in older desktop workflows.
Will the VTT file be bigger or smaller than my ITT?
It depends on the content: files begin with WEBVTT and optional metadata headers before the first blank line. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my ITT file?
In .itt, the frame-rate parameters are read because timing depends on them; styling attributes are dropped, since millisecond caption targets have nowhere to record them. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert VTT back to ITT?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .itt → .vtt → .itt is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
