What this utility does
Read a local file of up to 2 MiB and encode its bytes as standard Base64 entirely in the browser.
Input and output contract
Exactly one local file up to 2 MiB is accepted. Standard Base64 text representing the exact selected bytes.
Important limitations
The result uses standard Base64, not a data URL and not Base64URL.
SaveEditor.com implements this utility as a deterministic browser-local operation. The conversion result depends only on the explicit input and selected options; it does not infer a game format or silently modify unrelated data.
