Free online TXT to M3U converter

A media player, smart-TV app, IPTV client, or car stereo may require an .m3u playlist instead of a list saved as .txt. Converting the file preserves the referenced media while making the list recognizable to software that supports M3U playlists.

What the TXT format is

.txt is a plain-text format with no required structure beyond characters and line breaks. Notepad, TextEdit, Linux text editors, IPTV tools, media managers, and other applications commonly create TXT files.

A TXT file can contain media filenames, local paths, streaming URLs, channel names, comments, or unrelated notes. Only valid paths and playable URLs become useful playlist entries; changing the extension does not repair incomplete paths or identify media automatically.

What the M3U format is

M3U is a plain-text playlist format supported by VLC, Kodi, IPTV applications, music players, smart TVs, and many car stereos. It stores references to media files or streams rather than the audio or video itself, so the playlist is small and easy to edit.

A basic playlist usually contains one path or URL per line:

/Music/Album/song.mp3
https://example.com/live/channel.m3u8

An extended playlist starts with #EXTM3U and can place metadata before an entry:

#EXTM3U
#EXTINF:-1,News channel
https://example.com/live/news.m3u8

M3U is not a media container and does not transcode, compress, or embed the listed files. Relative paths depend on the playlist's location; absolute paths remain valid only on systems where those paths exist.

How to convert TXT to M3U

Manual conversion is sufficient when the TXT file already contains one valid filename, path, or URL per line:

1. Open the file in Notepad, Notepad++, TextEdit in plain-text mode, or another plain-text editor.
2. Remove headings, numbering, explanatory text, and invalid entries. Keep one playable path or URL on each line; blank lines are best removed for compatibility.
3. Add #EXTM3U as the first line. Many players also accept a basic list without this header, but the header identifies the file as an M3U playlist.
4. Use File → Save As, choose UTF-8 encoding, and save with a name ending in .m3u. Disable an option that automatically appends .txt; otherwise the result may be playlist.m3u.txt.
5. Open the saved playlist in VLC or the intended device and test several entries. A successful conversion does not prove that every referenced file or stream is available.

On macOS TextEdit, choose Format → Make Plain Text before saving. On Linux, a graphical file manager can rename the extension, or a terminal can use mv playlist.txt playlist.m3u after the contents have been corrected. Renaming alone changes only the filename, not the file's contents.

Using the 101convert converter

You can convert the file on 101convert.com for free without installing software. Upload the TXT file, choose M3U when the output format is requested, start the conversion, and download the resulting playlist. The output still requires checking when the source contains labels, mixed formatting, invalid paths, or URLs that are not direct media resources.

Converting a plain list with commands

On Linux or macOS, this shell command adds the header and removes empty lines:

{ printf '#EXTM3U\n'; sed '/^[[:space:]]*$/d' playlist.txt; } > playlist.m3u

On Windows PowerShell, use:

@('#EXTM3U') + (Get-Content -LiteralPath playlist.txt | Where-Object { $_.Trim() -ne '' }) | Set-Content -Encoding utf8 -LiteralPath playlist.m3u

These commands assume every non-empty source line is already a valid media path or URL. They do not verify files, convert media codecs, create #EXTINF metadata, or repair paths.

Compatibility limitations

• Use absolute paths when the playlist will be moved independently of the media. Use relative paths when the playlist and media retain the same folder relationship.
• Windows paths such as C:\Music\song.mp3 are commonly accepted, but some players handle backslashes or drive letters inconsistently. Test the target player before distributing the playlist.
• UTF-8 is the best default for accented and non-Latin filenames. Older players may require a UTF-8 BOM or another encoding; change the encoding only if the target software documents that requirement.
• #EXTINF metadata is optional and may be ignored by basic players. A simple header plus entries is generally the most portable structure.
• A URL must point to a directly playable stream or media resource. A webpage, expired link, login-protected address, or unsupported stream will not work because it appears in an M3U file.
• The conversion changes a text playlist into another text playlist. It does not reduce the size or change the quality of the referenced audio and video.
