About this tool
Encode and decode Base64 with full UTF-8 support. Convert text both ways, or drop in a file to get a Base64 string or data URI — all computed locally.
- 1Type or paste text to encode, or switch to decode mode to reverse it.
- 2Text is encoded via TextEncoder so multi-byte and emoji survive the round trip.
- 3Drop in a file to produce a Base64 blob or a data: URI you can paste anywhere.
- 4Everything is computed locally — nothing is uploaded.
Private by design
Everything runs locally in your browser. Your text, files and images are never uploaded to a server — the entire tool works offline once the page has loaded.
