Base Encoder/Decoder

Encode and decode text with Base16, Base32, Base58, Base62, Base64, Base85 and Base91 schemes

About Base Encoder/Decoder

Base encodings map binary data into printable characters and are widely used in API transport, signature payloads, short IDs, and text-based channels.

Key Features

  • Supports seven schemes: Base16, Base32, Base58, Base62, Base64, Base85, and Base91
  • Bidirectional conversion between plain text and Base-encoded strings
  • Includes paste, copy, download, and sample data shortcuts
  • Runs fully in-browser without uploading your input

When to Use Each Base

  • Base16: easiest to inspect for hashes and binary debugging
  • Base32: better readability with case-insensitive workflows
  • Base58/Base62: compact output for short links and identifiers
  • Base64: most common transport format in web protocols
  • Base85/Base91: denser output for shorter encoded strings

How to Use

  1. Choose conversion direction (encode or decode) and Base type.
  2. Paste your plain text or encoded string into the input area.
  3. Click Convert to generate output instantly.
  4. Copy, download, or swap input/output for chained operations.

FAQ

Is Base encoding encryption?

No. Base encoding is a representation format and does not provide cryptographic security.

Why does decoded text look garbled?

The original bytes may not be UTF-8 text, or the selected Base type does not match the input.

Will my data be sent to a server?

No. All conversion is performed locally in your browser.

Data is processed locally in your browser by default and will not be uploaded to any server. Upload will be clearly indicated if required.
