KaijuConverter is a free online file conversion platform built for speed, security, and simplicity. We support 198+ file formats across images, video, audio, documents, ebooks, spreadsheets, presentations, archives, and more.
Our Mission
File conversion should be effortless. No software installs, no account creation, no hidden fees. Just upload, convert, and download. We built KaijuConverter to be the fastest and most reliable way to convert files online.
How It Works
Our cloud-based conversion engines process your files on dedicated infrastructure. Each conversion runs in an isolated container, ensuring both performance and privacy. Files are automatically deleted within 60 minutes of upload.
For Developers
Need file conversion in your app? Our RESTful API lets you integrate conversion capabilities with just a few lines of code. Free tier includes 50 conversions per month.
KaijuConverter is built and maintained by Pablo Cirre, an independent software engineer based in Granada, Spain. Every conversion engine, the privacy model, and the multilingual catalog are developed and operated hands-on — not outsourced. Questions and feedback are always welcome via LinkedIn.

- Files are sent over an encrypted (TLS) connection and automatically deleted within 60 minutes of upload.
- GDPR-aligned: we never read, share, or sell your files or your data.
- Each conversion runs in an isolated environment — your content stays yours.
