Base64 / Base58 / Base32 Encoder

Encode and decode text using Base64, Base58, or Base32 directly in your browser.
You can switch between encoding modes with tabs and instantly view the results.

This tool supports UTF-8 text, including line breaks and non-ASCII characters, making it suitable for handling multilingual content and structured data.
Encoded results can be copied with a single click for use in APIs, filenames, URL-safe payloads, or configuration values.

All processing is performed locally in your browser.
No input data is sent to any server, ensuring a fast and secure encoding experience
for development, testing, and debugging tasks.

Guide: How to use & features

  • Paste the text you want to convert, then hit the Encode/Decode buttons in each tab to get results.
  • Toggle URL Safe or remove line breaks for Base64 and reuse the same input for Base32 or Base58.
  • Use the copy buttons to move any output elsewhere; large payloads may need a moment to finish.
  • All processing stays in the browser—your input is never sent to a server.

FAQ: FAQ

  • How do I choose between Base64, Base58, and Base32?

    Base64 is the most compact and is used for embedding binary data in email, data URIs, and the like. Base58 removes look-alike characters such as 0/O and l/I, which suits values people read or type by hand, like crypto addresses. Base32 uses only uppercase letters and digits and is case-insensitive, making it safe in strict environments such as URLs and some file names.

  • What does the URL-safe option change?

    Standard Base64 uses + and /, which can have special meaning in URLs and file names. URL-safe mode replaces + with - and / with _ so the output can sit directly in a query string or path. The side that decodes it must expect the same URL-safe form.

  • Is Base64 encryption — can I use it for sensitive data?

    No. Base encodings simply turn data into readable characters, and anyone can reverse them without a key, so they provide no secrecy. To protect sensitive data, use encryption (such as AES), not encoding. Encoding is only a representation change for carrying data safely.

Use cases: Common use cases

  • Inspecting tokens or log snippets

    Switch between Base64/32/58 to decode signed tokens or configuration strings and verify their contents safely.

  • Preparing payloads for API tests

    Convert images or binaries to Base64 for request bodies, or decode responses back to check the underlying data.

  • Agreeing on an exchange format

    Toggle URL-safe and strip-newline options to match the exact encoding format expected by partner systems.

Notes: Notes & limitations

  • Work stays in your browser

    Inputs and outputs remain local. Closing the tab or clearing cache will remove any temporary state.

  • Validate critical data

    Results are helper outputs—double-check them before sending to production systems or sharing externally.

  • Large payloads depend on your device

    Very large text or files can feel slow in some browsers. Use a desktop environment for heavy workloads.

UTF-8 friendly. Base64 output works well for filenames or URL-safe payloads.

Base64

Base64, Base58, and Base32 Encoder/Decoder

Base encodings are used to represent binary or structured data as plain text. This tool helps encode and decode Base64, Base58, and Base32 strings directly in the browser, which is useful when working with API payloads, tokens, hashes, keys, URLs, and debugging data formats.

Common use cases

  • Decode API payloads: Inspect Base64-encoded fields in logs, requests, or responses.
  • Prepare text-safe values: Encode data for configuration, URLs, headers, or test fixtures.
  • Compare encoding formats: Check how the same input appears as Base64, Base58, or Base32.

Things to watch

Encoding is not encryption. Base64 or Base58 can be decoded by anyone who has the string. Do not treat encoded secrets as protected data, and be careful when sharing API keys, tokens, cookies, or private material.
