Frequently asked questions

Everything you need to know about Proteus Convert.

  • No. Every conversion happens entirely inside your browser using WebAssembly and the File API. Your file is never uploaded to our servers — we have no server-side processing at all. The converted result is downloaded directly to your device.

  • You can run conversions without an account. An account is only required to download the result. Sign-up is free and takes under a minute — no credit card needed. You receive 20 free credits on sign-up.

  • Every conversion costs exactly 1 credit, regardless of file size or format. Free accounts get 20 credits on sign-up and can top up with credit packs that never expire. Pro ($6.99/mo) includes 600 credits per month; Business ($19.99/mo) gives unlimited conversions.

  • Documents: PDF, CSV, DOCX, JSON, XML, YAML, XLSX. Images: JPG/JPEG, PNG, WebP, HEIC/HEIF. Video: MP4, MOV, AVI, MKV. Audio: MP3, WAV, FLAC. Drop any supported file onto a converter or use the Browse button to select it.

  • No artificial size cap — all plans support unlimited file sizes. PDF → CSV handles documents up to 2,000 pages. Video and audio files work best under 500 MB for reasonable in-browser performance.

  • We store only your email address, credit balance, and anonymous conversion counts for billing purposes. We never see, store, or transmit your files — conversion is entirely local. We do not sell your data or share it with third parties.

  • Yes. You can upgrade, downgrade, or cancel at any time from your account settings. Credit packs purchased separately never expire and remain in your account regardless of plan changes.
