Base64ix

Encode and decode Base64 right inside your editor — UTF-8 safe, with URL-safe support.

Features

• Encode Selection — standard Base64 (SGVsbG8=).
• Encode Selection (URL-safe) — -_ alphabet, no padding, safe in URLs and JWTs.
• Decode Selection — accepts both standard and URL-safe input, with or without padding.
• Smart Encode/Decode — detects whether the selection already looks like Base64 and flips it the other way.

Every selection is processed independently, so multi-cursor edits work. Encoding uses UTF-8, so emoji and accented characters round-trip correctly.

Usage

1. Select the text you want to transform.
2. Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P).
3. Run a Base64ix: command.

If a selection isn't valid Base64 when decoding, Base64ix reports the reason and leaves your text untouched — it never writes a partial or garbled result.
