A phone ringtone editor or older mobile device may require a ringtone text file rather than a standard MIDI sequence. Converting MID to RTX is useful when that target device or program specifically supports RTX.
What the MID format is
.mid files usually contain Standard MIDI File data: timed note events, instrument program changes, tempo, and other performance instructions. They are created or exported by notation programs, digital audio workstations, and MIDI sequencers, and are commonly used to exchange editable music between them.
What the RTX format is
In music composition, RTX is a text-based ringtone format used by some mobile phones and ringtone tools. It represents a tune as ringtone events rather than as the general-purpose MIDI event stream, making it suitable for compatible ringtone editors and devices.
How to convert MID to RTX
Online on 101convert.com
- Open the MID-to-RTX converter page on 101convert.com and upload the MIDI file.
- Start the conversion and wait for the RTX output.
- Download the converted file. The page supports batch conversion; check its displayed per-file size limit before uploading.
Offline with desktop software
Awave Studio for Windows can open MIDI files and export supported ringtone formats. Open the file with File → Open, then use File → Save As and choose RTX if it appears in the output-format list. If RTX is not listed in your installed version, that version cannot perform this conversion; changing the filename extension does not convert the data.
Quality and compatibility
RTX ringtone formats support a narrower set of musical events than MIDI. The conversion may omit instruments, controller data, or notes that the target RTX format cannot represent, so check the result in the intended phone or ringtone editor. Keep the original MID if you need the full arrangement for later editing.
