Base64 Encode / Decode
Encode text or files to Base64, then decode Base64 back into text or downloadable files. Everything runs locally in your browser. Files never leave your device.
Before you start
Upload
Use text input or drop a file. File processing uses browser APIs and runs locally.
Result
Copy Base64 output, download it as a text file, or decode Base64 into a file download.
Local processing
Processing runs in your browser session. Files are not uploaded by default.
Limitations
Base64 increases file size and does not encrypt content. Treat encoded data as plain data.
