How do I convert a PDF to Markdown for free?

Upload your PDF to mdisbetter.com, click Convert, and get clean structured Markdown in seconds. No signup, no installation — it works directly in your browser.

Why is Markdown better than PDF for AI?

Markdown reduces token usage by up to 95% compared to PDF when feeding documents to AI models like ChatGPT or Claude. PDF contains layout metadata, fonts, and binary data that waste tokens. Markdown preserves only the content structure that AI actually needs.

What file types can MDisBetter convert to Markdown?

MDisBetter converts PDF, Word (.docx), plain text, YouTube videos (transcript extraction), audio files (MP3, WAV, M4A, OGG, FLAC, WEBM), and any web page URL to clean Markdown.

Is MDisBetter free to use?

Yes, MDisBetter is completely free. You get 10 conversions per day with no signup required. All tools work directly in your browser.

How do I extract a YouTube transcript as Markdown?

Paste the YouTube video URL into the YouTube to Markdown tool on mdisbetter.com and click Convert. The tool extracts the transcript and structures it as clean, formatted Markdown with headings and timestamps.

How accurate is AI transcription compared to human?

Human transcription is ~99% accurate and costs $1-2 per audio minute, takes hours to days. AI transcription via Whisper-class models hits 92-97% on clean audio (single mic, native or fluent speaker, quiet room), 85-92% on phone audio or accented speech. For working transcripts and most professional use cases, AI accuracy is sufficient with audio-verification of any quote that ships in publication. For high-stakes verbatim records (court testimony, regulatory filings), use human transcription.

How fast is the turnaround?

A 60-minute audio file typically transcribes in 2-5 minutes on the web tool. Compare to human transcription: hours to days. The speed difference is what makes AI transcription a practical part of daily workflow rather than a once-per-project task.

What's the difference vs Otter, Rev AI, AssemblyAI?

All use similar Whisper-class models or comparable competitor models. Otter is consumer-friendly with team workspace features ($16+/mo per user). Rev AI is API-first for developers. AssemblyAI is enterprise API. mdisbetter is the free no-signup alternative for one-off conversions, with structured Markdown output (speakers + H2 sections + timestamps) as the differentiator vs the flat-text output most competitors give you. Different price points, different feature sets — pick what matches your workflow.

Is there a file size or length limit?

Free tier handles typical interview/podcast lengths (up to ~60 minutes per file). Pro handles multi-hour recordings. For files larger than the free limit, split with any audio editor (ffmpeg, Audacity) before upload. File format and bitrate don't affect the limit; total duration does.

What audio quality do I need for good results?

Single-mic recording in a quiet room — accuracy 92-97%. Multi-person recording with separate mics per speaker — same range, 92-97%. Phone-call recording — 85-92%. Conference room with one centre mic and several speakers at distance — 75-85%. Heavy background noise (cafe, street, construction) — 70-80%. For challenging audio, run a cleanup pass first (Adobe Podcast Enhance, Krisp, Auphonic) before transcribing — typical accuracy boost is 5-15%.

AI transcription vs human transcription

Human transcription services (Rev, Scribie, GoTranscript) charge $1-2 per audio minute and take hours to days. Human accuracy is ~99%. AI transcription is dramatically cheaper, returns in minutes, hits 92-97% accuracy on clean audio. For working transcripts, content repurposing, research coding, and most professional use cases, AI accuracy is sufficient with a verification pass against the audio for any verbatim quote. For high-stakes verbatim records (court transcripts, regulatory testimony), human transcription remains the right choice.
