Base64 Encode/Decode for Mac
Need to encode or decode Base64 strings without opening a website? TextStow handles Base64 encoding and decoding locally on your Mac — perfect for API auth tokens, data URIs, and binary payloads.
Base64 Is Everywhere in Development
HTTP Basic Auth headers, data URIs, JWT token debugging, binary-to-text encoding, and API authentication all use Base64. Developers and QA engineers need to encode or decode Base64 strings constantly during API testing, integration work, and log analysis.
Encode and Decode Base64 Without Opening a Website
Copy any text or Base64-encoded string and process it with TextStow built-in Base64 tool directly from your menu bar. Get the result instantly — no browser tab switching, no external website navigation, no workflow interruption.
Keep Sensitive Base64 Payloads Local
Many Base64 strings contain sensitive data: API keys, authentication tokens, internal user identifiers, or proprietary configuration. Processing them locally means these strings never leave your Mac and are never visible to third-party servers.
Base64 Is Part of a Larger Text Toolbox
Base64 encoding rarely happens in isolation. When debugging APIs, you often need JSON formatting, URL encoding, and text cleanup in the same workflow. TextStow keeps all these tools in one place so you do not need five different websites.
History Makes Encoded Payloads Recoverable
Copied a Base64 token earlier but closed the terminal? TextStow clipboard history keeps both the original text and encoded/decoded output searchable. Find any Base64 string you processed, even hours later.
Offline Base64 Utility for Mac Menu Bar
Web-based Base64 tools require internet and expose your data to external servers. TextStow Base64 encoder/decoder runs entirely offline from your menu bar — available even on flights, in secure environments, or when your connection is unstable.
