Encode text to Base64, decode Base64 safely, validate payloads, and use URL-safe Base64.
Text, files, and bulk lists are processed locally in your browser.
Blank lines are skipped. Binary decode rows are identified instead of being forced into invalid text.

Examples follow your current mode, variant, character encoding, padding, and wrapping options.
Code uses placeholder input so your current text or decoded data is never inserted into the example.
Base64 Encoder / Decoder is made for quick date & time tools tasks where opening a heavy app would slow you down. Paste the input, choose the option that matches your work, and use the clean result in your next step.
