❓Frequently Asked Questions
Q: Why does conversion fail?
A: The most common reason is that the video source doesn't support CORS. Ensure your M3U8 link allows browser access.
Q: What's the maximum file size supported?
A: We recommend converting videos smaller than 100MB. Large files may cause browser memory issues.
Q: What about video quality?
A: The conversion process doesn't re-encode, maintaining original video quality by simply merging segments into a complete MP4 file.
Q: Are encrypted M3U8 files supported?
A: Currently, AES-encrypted M3U8 files are not supported. Only standard unencrypted formats are supported.
