Base 64

Base64 is a common encoding format used to convert text or file data into a safe, readable string that can be sent through systems that don’t handle special characters properly. The Base64 Encoder / Decoder tool helps you instantly convert normal text into Base64, and convert Base64 back into readable plain text—directly inside your browser. It’s especially useful for developers, SEO teams, and website owners who work with APIs, JSON payloads, authentication headers, email templates, WordPress integrations, or any system where encoded strings are required. Since everything runs locally in your browser, no text is uploaded and no data is saved, making it safe to use for client projects or private content.

This tool is built to handle real-world Base64 scenarios properly. The encoder uses UTF-8 safe encoding, so it works with normal English text as well as special characters, emojis, and non-English languages without breaking. For decoding, it includes a reliable “Decode FIXED” approach that normalizes Base64 input safely by removing extra spaces/new lines, supporting URL-safe Base64 (using - and _), restoring missing padding (=), and even decoding Base64 from data URI formats like data:text/plain;base64,.... This makes it far more dependable than basic Base64 tools that often fail when the input is slightly different or copied from real production systems.

To make workflows faster, the tool includes helpful advanced options such as URL-safe output, remove padding, and wrap lines (76 characters—useful for emails and some transport formats). It also includes a smart setting that lets you choose the decode input source: either decode from the Base64 field (default) or decode from the plain text area—so you can work in the way that fits your situation. You can also upload a file (like .txt, .json, .csv, .log, or .b64) to load Base64 content instantly, then copy the result with one click. Whether you’re debugging API requests, verifying encoded data, or converting text for safer transport, this tool gives you a clean, fast, and reliable Base64 experience.
