Base64 Encode / Decode Online
IPOK dev tools provide fast network diagnostics and data conversions, including IP purity, subnet risk, DNSBL blacklist, and ASN routing lookups.
Base64 encodes arbitrary data into ASCII text. Developers use it constantly for debugging, decoding cookies / tokens, and proxy users use it to decode subscription links.
This tool encodes/decodes entirely in your browser (UTF-8 safe), with no server round-trip. Proxy subscription links (ss:// vmess:// or clash) are usually a Base64 blob — paste and Decode to see the plaintext node config.
Tip: proxy subscription links (ss/vmess/clash) are usually Base64 — paste and Decode to see the plaintext nodes. Everything runs locally, never uploaded.
