Octal encode bytes
Unix file mode style octal beside hex dumps.

Nearby workflows on Toolcore
- Hex dump text — Classic hex + ASCII dump of UTF-8 bytes. Useful when the payload needs another alphabet or escape format.
- chmod & umask — Owner/group/other rwx to octal, ls-style rwxrwxrwx, copy chmod, and umask 022/002 quick reference for new files and dirs—local only. Useful when the payload needs another alphabet or escape format.
- LEB128 (ULEB + SLEB) — Encode/decode unsigned and signed LEB128 (WebAssembly, DWARF, varint-style) from decimal or hex; BigInt in the browser. Useful when the payload needs another alphabet or escape format.
- Encoding tools — Hub index: Base64 & URL, Base64url, Base32, Crockford, LEB128, ASCII85, Z85, Base58, base-36, bencode, Morse, quoted-printable, URI, Punycode/IDN, Unicode escapes, data URLs, MIME, hex, HTML entities, JWT, JSON helpers, crypto. Useful when the payload needs another alphabet or escape format.
Common use cases
- Transform sample text with octal encode bytes while debugging legacy email, Usenet, or protocol payloads.
- Compare output size and alphabet against Base64, Z85, or hex dumps on the same input without leaving the encoding hub.
- Unix file mode style octal beside hex dumps.
- When the payload also needs a sibling encoding, open the related encoding-hex-dump page from More tools below.
Common mistakes to avoid
Treating UTF-8 paste as raw binary
These tools encode the UTF-8 bytes of your text unless the page states otherwise. For arbitrary byte arrays, convert from hex first.
Mixing alphabets between encodings
Base91, Z85, uuencode, and Base64 use different symbol sets—decode with the matching tool before re-encoding.
Pasting secrets into shareable prefill links
URL query parameters may appear in browser history. Use Load example for demos; avoid ?q= links for production keys.
FAQ
Where does encoding run?
In your browser. Toolcore does not need your paste for the transform.
Is there a payload size limit?
Very large pastes may slow the tab. Split huge files locally before encoding samples on the page.
Can agents prefill this page?
Yes. Use ?q= for short text or ?qb= for base64 payloads on the tool URL.
