Frequently asked questions
Is converting TOML to JSON free?
Yes. There is no sign-up, no watermark and no limit on the number of files.
Are my files uploaded?
No. Everything runs in your browser, so your files are never uploaded to a server. That also makes it fast, because nothing has to travel over the network.
Will I lose quality converting TOML to JSON?
No noticeable loss: the conversion keeps the content of your TOML file intact.
Can I convert several files at once?
Yes. Drop as many TOML files as you like. They are converted one after another and you can download them individually or as a ZIP.
Is there a file size limit?
There is no fixed limit. Very large files depend on your device's memory, since the conversion runs locally.
What is TOML?
