The rules, short version

Drop a file in, get a converted file out. That's the whole deal. You don't need an account. There's no usage limit. Convert your own files or files you have permission to convert, we can't check, but it's on you.

We aim for the conversion to produce a reasonable result for any well-formed input file. We test 192 converters on every push with structural validation, round-trip equivalence, and adversarial fuzz tests.

We do not promise the conversion will be perfect for every file. Some conversions are inherently lossy (e.g. PDF to DOCX necessarily flattens layout). The output may not be a byte-for-byte equivalent in every case. Verify important conversions before relying on them.

• Uptime. The site is hosted on Vercel and the static files are CDN-served, but we don't guarantee a service-level agreement.
• That every browser will work. We test in current Chrome/Safari/Firefox. Older browsers may not have the WebAssembly or Canvas APIs some converters need.
• That your file is safe to convert. If you drop in a corrupted or malicious file, the conversion may fail or behave unexpectedly. The engine validates file shapes but is not an antivirus.

You're responsible for:

• Having the legal right to convert the files you drop in (copyrighted material, etc.)
• Verifying the converted output is correct for your use case before submitting it anywhere important (court filings, official documents, etc.)
• Not using the tool to violate anyone else's rights or applicable laws

twineconvert is a free tool provided as-is. We're not liable for losses arising from conversion errors, format incompatibilities, or the output not meeting your expectations. Verify important conversions yourself before relying on them.

We may update these terms. Material changes will land in the public GitHub repo first; the current version is always what's on this page.
