How to Use the Base64 Tool

1
Choose a mode

Single Line — treats the entire input as one value. Multi Line — processes each non-empty line independently. Kubernetes Secret — parses YAML and decodes values inside data / binaryData sections.

2
Pick Encode or Decode

Encode converts plain text → Base64. Decode converts Base64 → plain text. Kubernetes Secret mode is decode-only.

3
Enter input or upload a file

Paste text into the input area or use Paste from clipboard. For Kubernetes mode, upload a .yaml / .yml file directly with the Upload button.

4
Run and reuse

Click Run to process. Use Copy Output to copy the result, or Use Output as Input to chain encode → decode operations without leaving the page.

Base64 is an encoding scheme, not encryption. It obscures data visually but provides zero security. Never use Base64 alone to protect sensitive information.
Single LineBest for encoding single tokens, secrets, or credentials. The entire input is treated as one value.
Multi LineEncodes or decodes each line separately. Useful for batch-processing lists of values in one pass.
Kubernetes SecretReads a kind: Secret YAML file and decodes all Base64 values under data and binaryData.
File UploadLoads the file content as text into the input. Supports .yaml, .yml, and .txt files.
