How It Actually Works
Most online converters upload your file to a server. Privvert doesn't - and you can verify it.
PDF, image, audio, video, code - pick any of 70+ tools.
WebAssembly + browser APIs do the work on your machine. Open DevTools → Network: nothing leaves.
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.
Merge, split, redact, sign and password-protect contracts without sending them to a third-party server.
Strip EXIF/GPS from photos, OCR scanned forms, compress patient files - all locally, no DPA needed.
JWT decode, JSON↔TS, hashes, regex, UUID, cron, base64, timestamps - without leaving production secrets in someone's logs.
HEIC→JPG from iPhone, background remove, image compress, favicon, color extraction - no Photoshop, no upload.
Redact PDFs, strip metadata from sources, extract text via OCR - sensitive material never leaves the device.
No upload wait, no server queue. A 200 MB video converts as fast as your CPU allows.
