Base64 encode

Client

Standard Base64 for binary-safe text.

About Base64 encode

Encode UTF-8 to standard Base64. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.

How to use this page

Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.

Limits and safety

Utilities here are for development and inspection—do not paste live production keys, PANs, or recovery codes into any browser tab you do not control.
