Frequently asked questions
Is this JPEG to PNG converter really free?
Yes, completely free. No account, no credit card, no watermark, no file size limit imposed by a paywall. Convifi is free to use forever.
Is my file safe when I convert JPEG to PNG?
Your file never leaves your device. All conversion happens locally in your browser using WebAssembly. There is no upload to any server — not even Convifi's.

Yes. Because it runs in the browser, it works on any device — iPhone, Android, Mac, Windows, or Linux — as long as you have a modern browser like Chrome, Safari, Firefox, or Edge.
How long does JPEG to PNG conversion take?
Conversion time depends on your file size and device. Most files convert in under 30 seconds. Longer videos or high-resolution images may take a minute or two. Nothing is being sent over the network, so your connection speed has no effect.
