Free audio file → text — quick online converter
_Updated May 2026._
Convert common audio and video files into plain text for free in minutes. This tool lets you upload formats like MP3, WAV, M4A, MP4, and more, then generate a readable transcript with optional subtitle output. The free flow includes speed vs quality settings, automatic language detection, and TXT or SRT exports. Processing runs asynchronously, so shorter files finish quickly while longer ones may queue. You get real output without hidden steps, with clear limits and a straightforward upgrade path if you need more control.
Try it now — upload your file and get text
You can start immediately by uploading a file and running a transcription. The flow is intentionally simple so you can see results before committing to anything else. After upload, you confirm the job, choose a speed or quality setting, and wait for the transcript to complete.
Here’s how the typical free flow works in practice. Upload your file, confirm the transcription, and let the system process it in the background. When it finishes, you can read and edit the text directly, then export it as a TXT or SRT file. If you leave the page, the job continues and can be recovered when you return.
- Upload a file (audio or video)
- Click “Start transcription”
- Choose Speed or Best quality (free tier setting)
- Wait for processing (may queue during busy periods)
- Review and edit your transcript
- Export as TXT or SRT
This is designed for quick, one-off use. You don’t need to configure anything complex to get a usable transcript.
Supported inputs and immediate outputs
The tool supports a wide range of common audio and video formats, so you can upload files from most recording devices, editing tools, or downloads without conversion. This removes a common friction point where users need to re-encode files before transcription.
You can upload the following formats directly:
- AAC
- FLAC
- M4A
- MP3
- MP4
- MPEG
- MPGA
- OGG
- WAV
- WEBM
Once processed, the free tier gives you two practical export options. TXT is ideal for reading, editing, or copying into documents. SRT is useful for subtitles in video players or editing software. Both formats are widely compatible and cover most basic use cases without requiring upgrades.
Language detection runs automatically across more than 100 languages. You don’t need to set a language manually unless you want to override detection. After transcription, you can edit the text inline before exporting, which helps clean up names, formatting, or small recognition errors.
How the free transcription works
Behind the scenes, the free tier uses self-hosted speech recognition models routed through a processing bridge. These include faster-whisper models and, in some cases, NVIDIA ParaKeet TDT variants. This setup balances accessibility with solid baseline accuracy, especially for clear recordings.
The key tradeoff is that free processing is asynchronous. When you submit a job, it enters a queue and is processed in order. Short files often complete quickly, while longer files may take more time depending on system load. You can leave and come back later without losing progress.
You also get a simple control over performance versus accuracy. The “Speed” option prioritizes faster turnaround, while “Best quality” uses a more thorough model configuration that may take longer but typically produces cleaner transcripts.
- Self-hosted models (faster-whisper variants)
- Optional ParaKeet model routing
- Asynchronous processing via queue
- Speed vs quality toggle on free tier
Accuracy is generally strong for clear speech, minimal background noise, and standard accents. Like all transcription systems, results vary with audio quality, overlapping speakers, and recording conditions. The built-in editor helps you fix issues quickly without reprocessing.
Realistic limitations and where free workflows break
The free version is intentionally useful, but it is not designed for complex production workflows. If you are transcribing a simple lecture or short clip, it works well. If you need structured transcripts, speaker separation, or high-volume processing, you will hit limits.
One major limitation is the absence of speaker identification. If you upload an interview or podcast with multiple speakers, the transcript will not label who said what. You will see continuous text instead of structured dialogue. For quick reference, this is fine, but it becomes difficult to use for publishing or editing.
Another constraint is export flexibility. TXT and SRT cover basic needs, but more advanced formats like DOCX or JSON are not included in the free tier. In addition, exports may include a watermark depending on usage context.
- No speaker labels (diarization not included)
- No word-level timestamps in free output
- Limited export formats (TXT and SRT only)
- Jobs may queue during peak usage
- Longer files take more time to process
These limits are intentional so the free tool remains accessible while reserving more advanced workflows for paid tiers. The goal is transparency, not restriction after the fact.
When to upgrade to a richer workflow
If your needs go beyond simple transcription, upgrading removes the friction points you will notice in the free tier. Paid plans use a different speech recognition provider with built-in speaker identification and more structured output.
For example, if you regularly work with interviews, podcasts, or meetings, speaker labeling becomes essential. Instead of manually editing who said what, the system handles it automatically. This alone can save significant time on longer recordings.
You also gain access to more export formats, batch processing, and advanced features that support real workflows rather than one-off use. This is especially relevant for creators, researchers, and teams working with multiple files.
- Speaker identification (who said what)
- Additional export formats (DOCX, VTT, JSON)
- Batch uploads and parallel processing
- Higher consistency for longer recordings

Practical examples: what you can do right now
A free tool is only useful if it solves real scenarios, so here’s how it performs in common situations. These examples show where the free flow works well and where you may want to upgrade.
A student uploading a lecture clip usually gets a clean block of text that can be exported as TXT. This works well for note-taking, reviewing material, or searching key terms. Minor edits are often needed, but the output is usable immediately.
A short podcast episode can be transcribed and exported as SRT for subtitles. This is useful for quick publishing or accessibility. However, without speaker labels, multi-host shows become harder to format properly, which is where a paid tier becomes more practical.
An interview clip highlights the main limitation. You will get the words, but not the structure. If you need to distinguish between interviewer and guest, or prepare content for publication, speaker identification becomes important.
These examples reflect the core positioning: free works best for simple, single-file transcription. More structured or repeated workflows benefit from upgrading.

FAQ
Q: How accurate is the free audio to text conversion?
Accuracy is generally strong for clear recordings with minimal background noise. The system performs well on standard speech and common accents, but results vary depending on audio quality and overlapping voices. Using the “Best quality” setting can improve results, especially for more challenging files.
Q: Does the free tool support long audio files?
You can upload longer files, but processing time increases and jobs may queue. The system is asynchronous, so you may need to wait longer during busy periods. For frequent or large uploads, paid plans provide a smoother experience.
Q: Are there any hidden limits or paywalls?
The free flow is usable without hidden steps. You can upload, transcribe, edit, and export in TXT or SRT. Limits appear in areas like export formats, speaker identification, and processing priority, not in basic access.
Q: Can I edit the transcript after it’s generated?
Yes, you can edit the transcript directly before exporting. This is useful for correcting names, punctuation, or formatting. You do not need to rerun the transcription to make small fixes.
Q: Does the free version include speaker identification?
No. Speaker identification (diarization) is available on paid plans only. Free transcripts do not label different speakers, even if multiple voices are present.
Q: What formats can I export in for free?
The free tier supports TXT and SRT exports. These cover basic text use and subtitle workflows. Additional formats are available on paid plans.
Q: Is my audio stored or saved automatically?
You can recover transcripts after processing, and jobs continue even if you leave the page. Saving and managing transcripts more extensively typically requires signing in.
Q: Do I need to install anything?
No installation is required. The tool runs entirely online. You upload your file, start the transcription, and download the result in your browser.
