Base64 Encoder / Decoder
Encode and decode Base64 with full Unicode support - text or files.
About this tool
Encode text to Base64 or decode it back, with full Unicode support - accents and emoji round-trip correctly. You can also encode a file to Base64. Everything runs locally, so credentials and tokens are safe here.
Is Base64 encryption?
No. Base64 is an encoding, not encryption - anyone can decode it. Never rely on it to hide secrets.
Why does Unicode sometimes break in other tools?
Many tools use btoa directly, which only handles Latin-1. This one converts through UTF-8 first, so any character works.
