What to know about JPG to HDR conversion
- HDR is lossless: it stores the decoded image exactly, which usually makes files larger than the original JPG, but prevents further quality loss when you edit again.
- HDR is best for HDR environment maps for lighting 3D scenes, and opens in Blender, 3D renderers and HDR viewers.

Frequently asked questions
Is it safe to convert JPG to HDR here?
Yes. Your files are processed entirely on your own device by WebAssembly code running in the browser. They are never uploaded, so nobody else can see them, and the converter keeps working even if your connection drops after the page loads.
Is there a file size limit?
There is no server-side limit. The only limit is the memory available to your browser, typically 1.5–4 GB on desktop computers.
Can I convert several JPG files at once?
Yes. Add as many files as you like; they are converted in parallel according to your device's CPU cores, and you can apply the same settings to all of them.
