Uuencode / Uudecode
Encode text or files as classic uuencode, or decode uuencode back to a binary download. Edit filename and Unix mode on the begin line.
Runs in your browser. Nothing is uploaded.
How it works
Encode text or a file
Type UTF-8 text for a live uuencode, or drop a file up to 5 MB. Set the begin-line filename and Unix mode (default 644).
Copy or save the .uue
Copy the uuencode block or download a .uue file. Send to decode jumps to the decoder with the same payload.
Decode to a file
Paste a begin … end block. The tool reads the filename from the header and lets you download the binary. UTF-8 payloads show a short preview.
What is uuencode?
Uuencode maps binary bytes to a 64-character printable set and wraps them in begin/end lines with a filename and mode. This tool encodes text or files and decodes uuencode blocks back to downloads entirely in your browser.
Why use this tool
- Classic uuencode begin/end format
- Encode UTF-8 text live
- Encode files up to 5 MB
- Editable filename and Unix mode
- Decode with header parsing and preview
- Runs in the browser — files stay on device
Questions
What is uuencode?
Uuencode is a legacy Unix encoding that turns binary into printable ASCII with begin/end headers — once common for email attachments.
What does the mode number mean?
It is a Unix permission triad such as 644. This tool writes it into the begin line; it does not change local file permissions when downloading.
Are my files uploaded?
No. Encoding and decoding run in this tab. Easy24 does not receive the file.
Is there a daily limit?
The free plan allows 20 uses per day for file encode/decode actions, with files up to 5 MB.
Do I need an account?
No. Open the page and use it.
Does it work on a phone?
Yes. It runs in the mobile browser.
