About UUencode Encoder
UUencode and UUdecode text or files with xxencode variant support for email-safe transfer.
UUencode Encoder converts text or files into the classic UUENCODED format that early mail systems used to move binary attachments over seven-bit channels, and decodes such payloads back to their original bytes. The xxencode variant is available for systems that prefer its slightly different character set, and the tool shows line lengths and byte counts so you can see exactly how the payload will expand. Paste a block, pick the direction, and copy the result with the encoding header intact. Use it for legacy archives, CTF challenges or reproducing an old mailing-list workflow. UUencode Encoder is free, runs in your browser and never uploads your data.

Frequently Asked Questions
Can the UUencode Encoder both encode and decode?
Yes. Switch the direction to encode text or binary into UUENCODED lines, or paste an existing encoded block and decode it back to the original bytes. The xxencode option works the same way in both directions, and byte counts let you verify the round trip.
Is UUencode Encoder free to use?
Yes. UUencode Encoder is completely free with unlimited use — no account, download or payment required.
Is my data uploaded to a server?
No. UUencode Encoder runs entirely in your browser. Your inputs are never sent to our servers or stored anywhere.
Does UUencode Encoder work on mobile?
Yes. The interface is fully responsive and works in any modern browser on Android, iPhone, tablets and desktops.
