Frequently Asked Questions FAQ
Is this tool completely free to use?
Yes! This tool is 100% free with no hidden fees, subscriptions, or invasive paywalls. We rely on unintrusive ads and voluntary donations to keep the service running for everyone.
Is my audio data safe? Will it be leaked?
Extremely safe. Once your file is converted and the SRT is returned, the source file is immediately destroyed from our cache cluster. This complies with modern privacy regulations and takes advantage of our architecture that doesn't rely on persistent storage.
What languages are supported?
The underlying Whisper Large V3 model natively supports automatic detection and high-precision transcription for hundreds of languages worldwide. Whether it's English, Chinese, or a niche language, it perfectly outputs the corresponding source language subtitles.
Why is there a 25 MB file limit?
This is limited by the hard throughput standards of the high-performance inference engine. For content larger than this size, please consider splitting it into smaller audio segments on your device before uploading for processing.
