Online audio to text transcription lets you upload a recording in your browser and get written text back in minutes — no software install. With PlainScribe you upload a file up to 1GB, get high accuracy on clear audio across 47 auto-detected languages, and pay $0.067/min ($4/hour) with no subscription. Your first transcript is free (up to 2 hours), no credit card.
Online transcription runs entirely through a website. You open the app, upload an audio or video file, and the service converts speech to text on its servers — then you download the result. There is no app to install, no plugin, and no local processing power required. That makes it the fastest way to handle a one-off interview, lecture, or podcast episode from any computer.
PlainScribe is file-based: you upload a finished recording and get a transcript back. It is not a live meeting bot that joins calls, and it is AI-only (no human typists). For sensitive material you can also run the offline desktop app, but for most jobs the browser workflow below is all you need.
Go to the transcription dashboard and sign up. Your first transcript is free (up to 2 hours) with no credit card, so you can test accuracy on your own audio before paying anything.
Drag your file into the browser or click to select it. PlainScribe accepts MP3, MP4, WAV, M4A, MOV, WebM, MKV, AAC, FLAC, OGG and other common audio and video formats, up to 1GB per file. For long recordings, a mono MP3 at 64–128 kbps keeps the file small without hurting speech accuracy.
Choose the spoken language or let PlainScribe auto-detect it across 47 supported languages. Click transcribe. The AI engine processes the file in minutes; you do not have to stay on the page.
When the job finishes, your transcript opens in the browser. Skim it, then download it and fix any misheard names, acronyms, or numbers — automated transcription is highly accurate on clean audio, but a quick review still pays off.
Download your transcript as TXT for documents, CSV for timestamped data, or SRT/VTT for video captions. You can also generate an AI summary from the same file.
Your first transcript is free (up to 2 hours) with no credit card. Beyond that, PlainScribe charges $0.067 per minute ($4 per audio hour) on a pure pay-as-you-go basis — no subscription and no per-seat fee. The minimum top-up is $10 (about 150 minutes of credit), and paid credits last a full year. Many "free" online tools cap you at a few minutes, watermark output, or require a monthly plan to export. Here is how the options compare:
| Service | Model | Price | Free tier | Notes | |---------|-------|-------|-----------|-------| | PlainScribe | Pay-as-you-go | $0.067/min ($4/hr) | First transcript free (up to 2 hrs), no card | Subscription-free; 30-day auto-delete | | Sonix | Hybrid | ~$0.167/min PAYG or $22/mo | 30 min trial | Higher per-minute rate | | Rev | Pay-as-you-go | $0.25/min AI | None | Pricier AI tier | | TurboScribe | Subscription | $10/mo | 3 files/day | Monthly commitment | | Otter.ai | Subscription | Free tier + paid Pro | Limited free tier | Live-meeting focused, per-seat |
Verdict: If you transcribe occasionally and want to avoid a recurring bill, PlainScribe's pay-as-you-go pricing is the cheapest honest option — you pay only for the minutes you actually upload, and the first 30 are free.
You skip downloads, updates, and operating-system compatibility headaches. You can transcribe from a Chromebook, a work laptop with locked-down installs, or a phone browser. And because PlainScribe deletes your files and transcripts after 30 days, you are not leaving a permanent archive on someone else's server.

Can I convert audio to text online for free? Yes — PlainScribe makes your first transcript free (up to 2 hours) with no credit card, which is enough to test it on a real file. After that it is $0.067/min pay-as-you-go. Be wary of "unlimited free" tools that watermark output or lock exports behind a subscription.
Do I need to install anything to transcribe audio online? No. The web app runs in any modern browser. You only need the desktop app if you want fully local, offline processing of sensitive audio.
What audio formats can I upload? MP3, MP4, WAV, M4A, MOV, WebM, MKV, AAC, FLAC, OGG and other common audio and video formats, up to 1GB per file on the web.
How accurate is online audio to text transcription? High on clean, single-speaker audio. Background noise, strong accents, and overlapping speakers reduce accuracy, so review the output before you publish.
Is my uploaded audio kept private? PlainScribe auto-deletes uploaded files and transcripts after 30 days. For confidential recordings, use the offline desktop app to keep everything on your own machine.
