FAQ

Good questions, honest answers.

Is FileWhirl really free?+

Yes. Every conversion is free — no account, no watermark, no daily limit. The only paid part is TranscriptAI, if you later want transcripts, notes or summaries from a file.

Do I need to sign up?+

No. You can convert without an account. You'd only sign in for TranscriptAI's paid features.

What happens to my files?+

Image conversions run entirely in your browser and never leave your device. Anything sent to our engines is processed privately and auto-deleted within one hour, along with its download link. We never use your files to train AI.

Which formats can I convert?+

500+ format pairs across audio, video, images, PDFs, documents, ebooks, data, archives, fonts and 3D meshes. Browse them all on the Tools page.

How good is the conversion quality?+

We use the same pro-grade engines professionals do — ffmpeg, LibreOffice, Tesseract, Whisper and Calibre among them. Some conversions (OCR, scanned PDFs, speech-to-text) are best-effort by nature; we aim for the best available result, not a guarantee of perfection.

Is there a file-size limit?+

Fair-use limits keep things fast for everyone. Most everyday files convert without issue; very large media simply take a little longer.

Can I convert straight from a link?+

Yes — paste a direct file link or a public video/audio page and we'll fetch it for you, no upload needed. There's a Chrome extension too that adds a right-click "Convert with FileWhirl". Public content you own or have the rights to only — we don't bypass DRM, paywalls or logins.
