Questions

How do I convert GPL to JSON?

Drop your GPL file on this page, or choose it. Anyfile converts it on your device in a moment and the JSON downloads straight away. To change it first, open it in the LUT and palette editor.

Is my GPL file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Can I convert several GPL files at once?

Yes. Drop them together and you get one ZIP with every JSON inside.
