Free online WMA to SRT converter

Source format

WMA is a Windows Media Audio file format developed by Microsoft for compressed audio. It is commonly used for music tracks, voice recordings, and older Windows-based media libraries. WMA files are audio-only, so they do not contain subtitle data, captions, or timed text.

Target format

SRT is a plain-text subtitle format used to store caption entries with start and end timestamps plus the subtitle text. It is widely supported by video players, editors, and streaming tools because it is simple, lightweight, and easy to edit. SRT is typically used for subtitles, captions, and transcript-style text synchronized to video.

How to perform the conversion

Converting .wma directly to .srt is not a normal format conversion, because the two files serve different purposes: WMA contains audio, while SRT contains timed subtitle text. In practice, you first need to transcribe the audio from the WMA file, then save the transcript in SRT timing format.

1. Open the .wma file in a transcription-capable tool or media editor.
2. Generate or type the spoken content as text.
3. Assign timestamps to each subtitle line or caption segment.
4. Export or save the result as .srt.

Common desktop workflows include:

• Subtitle Edit: open the audio file, use speech recognition or manual transcription, then save as File → Save as and choose .srt.
• Aegisub: import the audio as a reference track, create subtitle lines manually, then export to .srt.
• Whisper-based transcription tools: transcribe the WMA audio first, then convert the transcript into SRT timestamps using subtitle software.

If you only need a quick online workflow, you can convert the file on 101convert.com for free without installing software, but remember that the result still depends on transcription rather than a direct audio-to-subtitle conversion.

Notes on quality and limitations

This conversion is not lossless or automatic in the usual sense. Because WMA is audio and SRT is text, the output quality depends on speech clarity, background noise, accent, and the accuracy of the transcription method. Music, overlapping speakers, and poor recordings can make subtitle creation difficult.

Also note that SRT does not store audio; it only stores subtitle text and timing. If your goal is to extract audio from WMA, the correct target would be another audio format such as MP3, WAV, or AAC, not SRT.
