Hey Product Hunt! 👋

I'm Tobi, creator of Morphio.

Like many of you, I convert files almost every week: client NDAs, tax receipts, iPhone HEIC photos for Windows, video clips for social media, or merged PDFs.

A few months ago, while converting a confidential contract on a popular "free online converter", I stopped and asked myself:

"Where is this PDF actually going? Who owns the server? How long is it cached? What prevents them from keeping my sensitive data?"

Almost every major converter uploads your files to a cloud server, queues them, converts them remotely, and lets you download them. If you deal with legal papers, medical records, client documents, or personal photos, that's an unnecessary privacy risk.

So I built Morphio — a privacy-first converter that runs 100% locally inside your browser:

🔒 Zero Cloud Uploads

Every conversion happens on your own device using WebAssembly (FFmpeg, 7-Zip, WebCodecs, PKIjs, Canvas, and Tesseract OCR). Your files never leave your computer or phone.

⚡ The Wi-Fi Acid Test

Don't take my word for it. Open https://morphio.tech, turn off your Wi-Fi / disconnect your network, and hit Convert. It keeps running smoothly offline. You can also open DevTools Network tab and verify zero file payloads.

📑 Complete PDF Studio & Cryptographic Signing

Merge, split, edit, compress, and digitally sign PDFs using personal or corporate .p12/.pfx PKI certificates directly on device.

🗜️ 1,300+ Formats Supported

- Images: HEIC, WebP, AVIF, PNG, JPG, SVG, TIFF, RAW

- Audio: MP3, WAV, M4A, FLAC, OGG, OPUS

- Video: MP4, WebM, MOV, MKV, GIF generator, Audio extractor

- Archives: 7Z, ZIP, TAR, RAR extraction, GZ

🔐 Morphio Lockbox & P2P Sharing

Client-side AES-GCM 256-bit encryption for sensitive files, plus peer-to-peer WebRTC file transfer between phone and desktop with zero server storage.
