Base64Anywhere
Base64Anywhere is a lightweight utility for encoding and decoding Base64 data on macOS. It lets users quickly Base64-encode entire files (including images like JPGs and PNGs) directly from Finder, and encode or decode text inline within text editors and programming IDEs. The app can display decoded binary data in hexadecimal format and automatically recognises and displays decoded image data as actual images rather than raw bytes. It is used by developers, web designers and anyone needing to work with Base64-encoded data structures.

1 suggestionBase64Anywhere now has an actively maintained successor called Base64 Toolbox, created by the same original developer (John Bowers), which ships as a native Apple Silicon build. Base64 Toolbox preserves all the functionality of Base64Anywhere—Finder integration, inline encoding/decoding in text editors, image recognition, and hexadecimal display for binary data—while adding UI improvements and running natively on M-series Macs. The transition is straightforward: download Base64 Toolbox from the MacUpdate link below, and your workflow carries over without migration. Since Base64Anywhere is no longer actively developed, moving to its native successor now ensures you will not face any issues when Apple removes Rosetta 2 in macOS 28 (September 2028).
