About Base92
Base92 uses 92 printable ASCII characters to encode data, slightly more compact than Base91 by adding one more character to the set.
How it works: the data is treated as a large number and converted to base 92 using a printable character table. The result is compact and remains text-safe.
Base92 is a choice for niche cases where every output byte is precious and you control both encode/decode sides. For general interoperability, Base64 is recommended.
FAQ
Can this Base92 tool both encode and decode?
Yes. This is a single page with a toggle — use Encode mode to transform text, and Decode mode to reverse it. No need for two separate pages.
Is my data sent to a server?
No. Base92 is processed entirely in your browser. The text you enter never leaves your device.
