Common questions about the JPEG to JPG converter
Are my files uploaded to a server?
No. uqln runs the conversion inside your browser using JavaScript and WebAssembly. Your files never leave your device, which also means there's no upload wait and no size limit beyond your device's memory.
Is it really free?
Yes. There's no account, no watermark and no daily limit. Because the work happens on your device, it costs us almost nothing to run.
Can I convert many JPEG files at once?
Yes. Drop as many files as you like. They're converted one after another, and you can download them individually or all together as a ZIP.
