I pasted the manifest, chose 1080p, and the tool handled the whole merge. No more command-line scripts for every stream.

About
M3u8 Downloader turns tricky HLS playlists into simple MP4 files. Paste a manifest URL or let the extension auto-detect streams on the page, pick the quality you want, and it will download every segment, forward the right headers, and merge the video in the background without command-line tools. It supports master playlists, CMAF/fMP4 segments, and multi-bitrate variants, retries failed chunks automatically, and runs in Chrome, Edge, Firefox, Brave, or Opera while keeping your browser responsive. The result is a source-quality MP4 you can archive, edit, or review offline.

Frequently Asked Questions
How do I download an m3u8 stream with this extension?
Paste the playlist URL into the popup or enable auto-detect on the page, select the quality variant you want, and start the conversion. The MP4 will save when segment merging completes.
Does it work with authenticated streams?
Yes. The downloader forwards cookies, referrers, and custom headers from your browser session so authorised streams play without manual configuration.
Can I queue multiple playlists?
You can add several manifests to the queue and the extension will process them sequentially, keeping your browser responsive while conversions run.
Which browsers are supported?
Builds ship for Chrome, Edge, Firefox, Brave, and Opera on Windows, macOS, and Linux. Safari is not supported.
Will it download DRM-protected or encrypted streams?
No. The tool works with unencrypted HLS playlists only. DRM-protected streams remain inaccessible.
Do subtitles or alternate audio tracks download?
The downloader captures the selected video/audio rendition. Subtitles or alternate audio tracks are not extracted; download them separately if required.
Is my data private?
All detection, downloading, and merging happen locally. Only licence verification touches external servers, and no analytics are collected.

I saved three-hour town halls back-to-back. Retries kept the downloads alive and quality is identical to the source.
