Lime Kit

Base64 Encode/Decode

Encode or decode Base64 text, or turn a file into a Base64 data URI. No uploads.

How to encode or decode Base64?

Switch between Encode and Decode, paste your text, and Lime Kit converts it instantly. Unicode text — emoji, accented characters, non-Latin scripts — is handled correctly, unlike plain btoa() which breaks on multi-byte characters.

Need to embed an image or document inline? Use the file section below to convert any local file into a ready-to-use Base64 data URI, computed entirely in your browser.
