//How It Works
Drop your file
Drag a file onto the drop zone, or click to pick one. The file goes from your disk straight into your browser's memory — never to a server.
Browser converts locally
A WebAssembly module runs on your CPU and decodes the file in real time. Verify it yourself — pop open DevTools, watch the Network tab. It stays empty.
Save the result
The browser hands you a download. For batch jobs, a single ZIP. Close the tab and everything's gone — no caches, no history, no server logs.
//Common Questions
Is this really 100% offline?
Yes. Once a tool page has loaded in your browser, all conversion logic runs locally via WebAssembly. You can verify by opening your browser's DevTools → Network tab before converting a file: you'll see zero outbound requests during conversion.
You can also disconnect your wifi after the page loads — the converter still works.
What's the file size limit?
There is no enforced limit — but your browser has practical memory constraints (typically 1–2 GB for a single in-memory buffer on desktop, less on mobile). For very large files, use a desktop browser with plenty of free RAM.
How do you make money if there's no upload?
PrivateConvert is free to use. The site is supported by a single optional affiliate link to pCloud (a privacy-focused encrypted cloud storage service) — useful for people who want secure long-term storage of the files they just converted. We never push it, and the tools work fully without ever clicking it.
What's HEIC, and why convert it?
HEIC (High Efficiency Image Container) is the format iPhones use by default for photos. It's smaller than JPG but most non-Apple devices, Windows software, and many websites still don't open it natively. Converting to JPG makes a photo universally compatible.
Is the source code open?
The conversion libraries we use (heic2any, libheif, jszip) are open source. The site code itself is hand-written static HTML, CSS, and JavaScript — everything you see is in the page source, no compiled bundles or hidden trackers. View source any time.
Do you track anything?
We use Plausible Analytics for aggregate pageview counts — it's cookieless, GDPR-compliant, EU-hosted, and stores no personal data. No file names, sizes, hashes, or contents are ever transmitted. See our privacy page for the full disclosure.
