Free and Secure Online M3U Playlist Editor

Most free online utility tools upload your credentials to remote servers. M3U Studio provides a fully featured editor that operates entirely locally.

No Account or Subscription Required

The current editor can be opened without registering or starting a subscription. That does not mean the website performs zero measurement: Google Analytics and AdSense code are installed, and hosting access logs may exist. Those services are described in the Privacy Policy.

There are also technical limits. A local text file over 50 MB is rejected and the parser stops after 500,000 entries. Available memory and device speed usually become relevant before a theoretical ceiling.

Process Large Files Instantly

The channel view renders only the visible portion of a long list, which reduces DOM work. Parsing, searching, sorting, and copying the underlying data still use memory and CPU. Do not treat the 500,000-entry safety stop as a performance promise; keep a source backup and start with a smaller regional subset on mobile devices.

Advanced Browser-Based Parsing

All file parsing occurs inside your local device memory. The browser parses text strings directly into high-performance Preact states, protecting private hashes.

Features at a Glance

Edit channel names, EPG groups, tvg-logo links, bulk-rename items, clean duplicates, validate active streams, and customize export formats.

Free does not mean unlimited or tracking-free

No account or subscription is currently required for the browser tools. The parser still rejects input over 50 MB and has an entry safety stop; device memory can impose a lower practical limit.

The playlist-processing code is local for selected files, while the website includes Analytics and AdSense. Review the Privacy Policy and use a fictional sample before loading credential-bearing URLs into any web utility.

Frequently Asked Questions

What stays on my device?

A file selected from your device is parsed and edited in browser memory. URL import and stream checking contact the third-party addresses you provide, while Analytics and AdSense process separate website data as explained in the Privacy Policy.

Which formats can I save to?

You can download as M3U, M3U8, CSV, JSON, XML, or TXT.
