Base64 Coder 2.1.0 for Mac
Mac Developer ToolsBase64 Coder is a small Mac utility for one everyday developer task: turning text into Base64 and turning Base64 back into readable text. Base64 shows up everywhere in development work, from data URIs and email attachments to API payloads and configuration values. Instead of opening Terminal and remembering command flags, you paste your text into the app, encode or decode it, and copy the result back into your project.
Key Features
- Encode plain text into Base64 in a couple of clicks
- Decode Base64 strings back into their original text
- Simple paste-in, copy-out workflow with no command line needed
- Useful for checking data URIs, tokens and encoded values while debugging
- Lightweight utility that does one job and stays out of the way
How to Download
- Check that your Mac runs a recent version of macOS before installing.
- Use the green Download button on this page, or visit the developer's website to check the current edition they offer.
- Install the app, paste in a test string, and encode and decode it once to confirm it behaves as you expect.
System Requirements
Base64 Coder runs on Macs with a recent version of macOS, on Apple silicon or Intel hardware. Encoding text is trivial work for any modern Mac, so system demands are minimal.
FAQs
Is Base64 the same as encryption?
No, and this matters: Base64 is only an encoding. Anyone who has the encoded string can decode it instantly, so never use it to protect passwords or secrets.
Can macOS do this without an app?
Yes, Terminal has a built-in base64 command. A small app like this one simply makes the same job quicker and less error-prone if you do it often.
