Why Free Whisper Transcription?
Most popular transcription tools advertise a "free tier" — then hit you with limits that make it practically unusable. Otter.ai gives you 300 minutes per month. Rev.com charges $1.50 per minute. Descript requires an account just to try it. Whisper Web is different: the local transcription mode is genuinely unlimited, forever free.
Truly Free
No credit card, no subscription, no metered usage. Local mode runs on your device — our servers aren't involved.
No Registration
Open the page and start transcribing. Unlike Otter, Rev, and Descript — we don't require an account to unlock the tool.
No Upload
Your audio data never leaves your browser. Free transcription without the privacy trade-off cloud services require.
Free whisper transcription online works because the Whisper AI model runs directly in your browser via WebAssembly — a portable instruction format that lets complex AI models execute in the browser at near-native speed. No cloud servers are needed, so there are no costs for us to charge you for.
How It Works
Choose Your Audio
Click Upload Audio / Video or record directly from your microphone. Supported formats include MP3, WAV, M4A, MP4, WebM, OGG, and more. File size up to 200 MB in local mode.
Whisper AI Processes Locally
On first use, the Whisper model (~77 MB) downloads once to your browser cache. After that, all transcription runs offline and locally — no audio is ever transmitted to a server. Language is detected automatically.
Copy, Edit, Export
Review the transcript in-browser, make any corrections, then export as TXT for plain text, SRT for video subtitles, or VTT for web captions. All free, all instant.
Free vs. Paid: What's the Difference?
Whisper Web's free local mode covers the majority of daily transcription tasks. Here is the free vs unlimited plan framing for buyers comparing browser tools to cloud subscriptions:
| Feature | Free | Unlimited ($20/mo) |
|---|---|---|
| File size | 200 MB | 5 GB |
| Max duration | 20 min | 10 hours |
| Cloud sync | ❌ | ✅ |
| Batch upload | ❌ | ✅ |
| API access | ❌ | ✅ |
| Priority support | ❌ | ✅ |
What Can You Transcribe for Free?
The short answer: almost anything with spoken audio. Here are the most popular use cases for free online Whisper transcription:
Podcast Episodes
Turn podcast audio into searchable blog posts or show notes. The SRT export lets you add chapter-accurate captions to your YouTube re-uploads. Completely free — no per-episode charge unlike most transcription services.
YouTube Video Audio
Download a YouTube video's audio (e.g., using yt-dlp or an online converter), then drop it into Whisper Web. Get an accurate transcript for repurposing content into articles, newsletters, or social media clips.
Voice Memos & Interviews
Researchers and journalists can transcribe field recordings, voice memos, and qualitative interviews without uploading sensitive data to a cloud provider. Ideal for GDPR-compliant workflows.
Lectures & Online Courses
Students can transcribe lecture recordings to create study notes, while course creators can generate accurate captions for their videos — all at zero cost per lecture.

Frequently Asked Questions
Yes. The local transcription mode is completely free with no time limits, no upload limits, and no account required. The Whisper AI model runs entirely in your browser, so there are no server costs for us to pass on to you. The site is supported by non-intrusive display ads.
There is no catch. Whisper Web is an open-source project built on top of OpenAI's open-source Whisper model. Since all computation happens on your device, we have no per-use cloud costs. Some very long files (>20 min) may require more RAM than entry-level devices have, but that is a hardware limit, not a pricing one.
Yes. In the free local mode there are no duration limits imposed by Whisper Web. The practical limit is your device's RAM and processing power. A 2-hour podcast on a modern laptop (8 GB RAM+) typically transcribes in 10–20 minutes. For very long files, consider splitting them into 30-minute chunks first for faster processing.
Yes. Once the free browser model has been downloaded, the assets can stay cached locally so you can reopen the page and keep transcribing without a constant connection.
For clear speech, free whisper transcription online is already competitive with many paid products. What you give up is extra SaaS workflow features, not the core benefit of accurate local speech-to-text.
