What is HLS streaming and why do I need it?
HLS (HTTP Live Streaming) is an adaptive streaming protocol that automatically adjusts video quality based on the viewer's internet connection. It's essential for providing smooth video playback across different devices and network conditions.
What quality variants are generated?
Our HLS generator creates multiple quality streams ranging from 360p (low bandwidth) to 4K (high bandwidth). Common variants include 360p, 480p, 720p, 1080p, and 4K, each optimized for different viewing conditions.
Which video formats can I turn into HLS?
Any video the in-browser FFmpeg engine can decode: MP4, MOV, MKV, WebM, AVI, WMV, FLV, M4V, 3GP, MPEG-TS (.ts, .mts, .m2ts), MPG/VOB, OGV, MXF, animated GIF and most other video files. Every rendition is re-encoded to H.264 and AAC, so the source codec doesn't matter. Two exceptions are named when they happen: AV1 video (this engine has no AV1 decoder) and copy-protected (DRM) files. An audio-only file belongs in the Audio HLS Stream Generator, and the tool links you there.
How do I use the generated HLS files?
Upload the entire ZIP contents to your web server or CDN. Use the master playlist (.m3u8 file) as the source URL in HLS-compatible video players like Video.js, HLS.js, or native players on iOS/Safari.
What's included in the HLS package?
The ZIP package contains: master playlist (m3u8), individual quality playlists, video segments (.ts files), and all necessary files for adaptive streaming deployment.
Can I customize segment duration?
Yes, you can configure segment duration from 2-10 seconds. Shorter segments provide faster quality switching but create more files. Longer segments reduce file count but slower adaptation.
Is there a file size limit for HLS generation?
The maximum input file size is 1GB. Processing time varies based on video length and the number of quality variants selected.
Are my videos uploaded to your servers?
No, all HLS generation happens locally in your browser using WebAssembly technology. Your video files never leave your device, ensuring complete privacy.
