Base64 Encoder
Encode and decode text or files to and from Base64 instantly.
Base64 is a text encoding scheme that turns binary or special text content into a plain ASCII string so it can be safely transmitted in URLs, HTML, CSS, API payloads, and email-friendly contexts. Need to clean up your text first? Try our case converter before encoding.
This free browser-only base64 tool lets you encode or decode content instantly while keeping every step local to your device, which means no upload is required and your data stays private.
It is especially useful for developers, designers, and technical teams who need to embed tiny assets, transport data through forms, or inspect encoded payloads without installing extra software.
