Base64 Encoder/Decoder

Base64 converts binary data to ASCII text so it survives email, JSON, and query parameters without corruption. It powers data URLs, email attachments, and many API payloads. Pare Dev Base64 supports encoding and decoding with instant feedback—use it when you need a quick sanity check before dropping tokens elsewhere. Results update as you type.

Encode: convert UTF-8 text or small binaries to a Base64 string. Decode: restore Base64 back to original bytes when padding is valid. Use for img src data URLs, CSS backgrounds, JWT segment inspection, and multipart debugging. Avoid pasting production secrets into third-party sites—this tool keeps traffic confined to your tab. Remember Base64 expands payload size by roughly four-thirds, so bundle carefully. When debugging mobile crashes, copy the crash snippet here before rehydrating protobuf or image blobs offline. Clipboard managers sometimes strip padding—toggle strict decode off in your head when trailing equals signs disappear after screenshots. Embedded firmware teams embed Base64 certs in JSON manifests; verify line wraps here before flashing devices.
