HLS Stream Generator

Converteer videobestanden naar HLS (HTTP Live Streaming) formaat met meerdere kwaliteitsvarianten voor adaptieve streaming. Alles wordt veilig in je browser verwerkt – je bestanden verlaten nooit je apparaat.

Overview

The HLS Stream Generator converts any local video file into a complete HTTP Live Streaming package — a master m3u8 playlist, per-quality variant playlists, and H.264-encoded .ts segments — ready to drop onto a CDN or web server. You choose the quality tiers (360p through 4K), segment duration, and encoding profile, and the tool produces a single ZIP you can deploy immediately. Because everything runs locally in your browser via WebAssembly, your video file never leaves your device: no upload, no cloud processing, no account needed.

Key Features

  • Meerdere kwaliteitsvarianten (360p tot 4K)
  • Instelbare segmentduur
  • Adaptieve bitrate streaming
  • H.264-encoding met aanpasbare profielen
  • Automatische master playlist generatie
  • Browsergebaseerde verwerking
  • Download als ZIP van het complete HLS-pakket

Common Use Cases

  • Self-hosted video streaming — Developers and sysadmins preparing video for a self-hosted player (Video.js, HLS.js) generate the full m3u8 package locally before pushing to their CDN.
  • Confidential or unreleased content — Content creators working on unreleased footage can package it into adaptive HLS streams without sending the source file to any third-party service.
  • Multi-device delivery — Teams building apps for iOS/Safari alongside Android and desktop need HLS because it is the only universally supported adaptive streaming format across those platforms.
  • Bandwidth-adaptive course videos — E-learning authors encode course recordings into multiple bitrate tiers so students on slower connections auto-drop to 360p without buffering.
  • Quick CDN deployment prep — Freelancers handling one-off video uploads to a client's CDN use the tool to produce a deployment-ready ZIP without spinning up FFmpeg locally or paying a transcoding API.

Frequently Asked Questions

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.

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.
