Frequently asked questions
How do I convert TOML to YAML?
Drop your TOML files onto the page, or click “Choose files”. You can add many at once, or a whole folder. YAML is already selected as the output. Optionally open Options to adjust indent, sort keys. Click Convert, then Save. Converting several files? Save them all as one ZIP.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly. Your files never leave your device, so it is safe for private photos, contracts and business data. Once the page has loaded it even works offline.
Will converting TOML to YAML reduce quality?
No. TOML to YAML conversion is exact: the data is parsed and rewritten, not approximated.
Can I convert multiple TOML files to YAML at once?
Yes. Add as many TOML files as you like; they are converted in parallel on your device and you can download them all as a single ZIP.
Is it free? Are there limits?
It is free, with no sign-up, no watermark and no daily limits. Because nothing is uploaded there is no upload size limit either; the only limit is your device’s memory, which matters mostly for very large videos.
