Generate an SRT Free ورود

Most "free" SRT generators cap you at 5–10 free minutes, then ask for a subscription. ZinAIStudio has no minute caps — upload your audio (up to 50MB per file), download the full SRT. And because the SRT is produced by our video pipeline, you also get a finished, subtitled HD video with it. Two deliverables, zero cost.

A standard .srt file ready for YouTube, Premiere, DaVinci, or any player — plus the bonus subtitled video, voice track, and script.

SRT generator — questions answered

How do I generate an SRT from audio for free?
Upload your MP3/WAV, let the AI transcribe it, and download the SRT from your project — no minute caps, no watermark, no credit card.
What exactly is in the SRT file?
Numbered captions with start/end timestamps, split at natural sentence boundaries — the standard SubRip format every major platform accepts.
Is there a length limit?
No per-minute caps. Files up to 50MB upload fine; for social clips, 60–90 seconds of audio is the sweet spot.
Do I also get a video?
Yes — the same pipeline produces a finished HD video with your captions burned in, at no extra step or cost.
What languages are supported?
The current speech-recognition model is English-optimised; other languages may transcribe with lower accuracy.
