Frequently asked questions

Will the Word file open correctly?▾

Only if the original Base64 was a valid .docx. Garbled input will produce a corrupt file.

How do I know which format my string decodes to?▾

If the string starts with a data URI prefix (data:application/...), the format is identified automatically. Without a prefix, choose DOCX (modern) unless you specifically need DOC (legacy Word).

What if the decoded file is corrupt?▾

Make sure the source Base64 string is complete and not truncated. Email or chat clients sometimes wrap long strings; whitespace is fine but missing characters break the decode.
