Encode and decode Base64 strings with proper UTF-8 support.
Convert text to Base64 for data URIs, tokens, and transport-safe payloads — then decode back with UTF-8 handling for international characters.
Naive window.btoa usage assumes Latin-1. We encode via TextEncoder so Unicode survives round-trips.
No. Base64 is encoding, not encryption. Anyone can decode it.
Paste the raw credentials or token string into ToolVera’s Base64 tool and copy the encoded output. Encoding happens in your browser—useful for quick header tests without sending secrets to a server.
Padding completes the last block so the length is a multiple of four. Most decoders expect it; strip padding only when a specific API documents that requirement.
