Add your M3U8 file
Drop one or more .m3u8 files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
M3U8 to JSON
Converting a .m3u8 font to .json repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .m3u8 font to .json repackages the same glyphs and metrics for a different delivery target. An .m3u8 file is a UTF-8 encoded M3U playlist. The extension began as nothing more than an encoding signal, and then became the manifest format for HTTP Live Streaming, where it lists media segments or alternate bitrate renditions rather than songs.
A .json file holds JavaScript Object Notation: nested objects, arrays, strings, numbers, booleans, and null written in a strict text syntax. It is the default data language of the web — most APIs speak nothing else. For this route the practical draw is parsers ship in the standard library of essentially every language and readable by humans and machines alike — balanced against no comments — a perpetual annoyance for configuration files, which is worth knowing before you commit a large batch.
Why convert M3U8 to JSON?
The practical trigger for this conversion is usually a mismatch: with .m3u8, one extension covers both trivial playlists and full HLS manifests. Switching to .json buys you parsers ship in the standard library of essentially every language, which is why it is the better fit for rEST and HTTP API request and response payloads. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
M3U8 vs JSON at a glance
| Aspect | UTF-8 M3U playlist (.m3u8) | JSON data (.json) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | always UTF-8 — that was the original and only reason the extension exists | exactly six value types; no dates, no comments, no trailing commas — the strictness is deliberate |
| Strongest at | serving adaptive-bitrate video over HTTP to browsers and mobile devices | rEST and HTTP API request and response payloads |
| Weak spot | one extension covers both trivial playlists and full HLS manifests | no comments — a perpetual annoyance for configuration files |
Pick JSON as the output
Select .json in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if JSON is selectable, the route is real and validated.
Convert on your device
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid JSON file. Outputs keep the original filename with the .json extension.
M3U8 to JSON questions, answered
Will converting M3U8 to JSON lose quality?
There is no visual quality to lose — m3u8 is text-oriented and json is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert M3U8 files here?
Yes — the .m3u8 file is processed inside your browser tab and never uploaded. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip. Close the tab and the file is gone from memory.
Where will the JSON file work?
Browsers parse it natively through JSON.parse, every mainstream language bundles support, and most editors validate and highlight it out of the box. Viewing a raw .json file is possible in any text editor or browser tab.
Will the JSON file be bigger or smaller than my M3U8?
It depends on the content: exactly six value types; no dates, no comments, no trailing commas — the strictness is deliberate. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my M3U8 file?
In .m3u8, segment and rendition references with their durations are preserved. HLS-specific tags such as encryption keys and discontinuity markers are not represented in simpler targets. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert JSON back to M3U8?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .m3u8 → .json → .m3u8 is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
