How It Actually Works

Most online converters upload your file to a server. Privvert doesn't - and you can verify it.

1. Drop a File in the Tab

PDF, image, audio, video, code - pick any of 70+ tools.

2. We Process It Locally

WebAssembly + browser APIs do the work on your machine. Open DevTools → Network: nothing leaves.

3. Download the Result

The output is generated in-memory and saved straight to your downloads. We never see it.

Why We Built Privvert

We started Privvert because the internet's "free file converters" are anything but free. They cost you your privacy. Every PDF you merge, every photo you compress, every audio file you trim on those sites gets uploaded to somebody else's server, scanned, logged, and often quietly retained and sold. We thought Americans - and everyone else - deserved better.

So we built Privvert the right way: a fast, modern web app where every conversion happens locally, on your device, using the same browser you're reading this in. We never see your files because we literally cannot see them. There's no upload endpoint. There's no cloud bucket. There's no "trust us." There's just math, running in your tab.

Built for People Who Can't Upload That File

Concrete situations where Privvert is the right tool - not a generic "convert online" site.

Lawyers & accountants handling client PDFs

Merge, split, redact, sign and password-protect contracts without sending them to a third-party server.

Healthcare & GDPR-bound teams

Strip EXIF/GPS from photos, OCR scanned forms, compress patient files - all locally, no DPA needed.

Developers in the flow

JWT decode, JSON↔TS, hashes, regex, UUID, cron, base64, timestamps - without leaving production secrets in someone's logs.

Designers & marketers

HEIC→JPG from iPhone, background remove, image compress, favicon, color extraction - no Photoshop, no upload.

Journalists & researchers

Redact PDFs, strip metadata from sources, extract text via OCR - sensitive material never leaves the device.

Anyone on a slow connection

No upload wait, no server queue. A 200 MB video converts as fast as your CPU allows.
