Online Base64 Decode & Encode
Unlock instant base64 decode, decode bas64, and reliable base64 encoding with this free online converter, designed for developers, security professionals, and power users who work with encoded data every day. Everything runs securely on the client side, so no data is ever sent to a server, keeping your sensitive information private and safe.
Effortless Base64 Decoding and Encoding
Use the built-in base64 decode online feature to convert any base 64 string back to its original form with a single click. The tool also supports base64 encoding so you can transform raw text or binary data into a compact, transport-safe string suitable for emails, APIs, HTML, CSS, and more.
URL Decode and Encoded URL Support
When you are dealing with messy query strings or redirect parameters, the integrated url decode feature helps you quickly clean and analyze any encoded url values. You can safely decrypt url parameters and inspect hidden data inside tracking links, redirect URLs, and API requests without installing extra software.
Decrypt Base64 Online
Combine url decode with the base64decode option to effectively decrypt base64 online and inspect layered encodings often used in modern web applications. This makes it an ideal tool for debugging, penetration testing workflows, and general troubleshooting of encoded url data.
Binary Decoder & Hex Decode Features
Advanced users can take advantage of the built-in binary decoder and decode hex capabilities to convert raw binary strings or hexadecimal values into readable text. This is especially helpful when working with low-level protocols, custom encodings, or debugging complex systems that combine multiple encoding layers.
Decode Bas64 Values
By supporting base 64, binary, and hex in a single interface, the tool becomes a versatile companion for developers and security researchers. Switch between modes to decode bas64 values, interpret binary payloads, and decode hex sequences without leaving your browser or using separate utilities.
Secure Local SHA-256 Hash Generator
Alongside decoding and encoding, the tool includes a secure SHA-256 hash generator that runs entirely in your browser. Generate strong, one-way hashes for password verification, data integrity checks, digital signatures, and blockchain-related workflows without exposing your input to remote servers.
Ideal for Security-Conscious Users
Because all hashing logic is implemented with client-side code, your raw text, secrets, or configuration values never leave your device. This provides a safer alternative to typical hash generators that upload data to a backend, making it ideal for security-conscious users and sensitive environments.
Why Use This Base64 and SHA-256 Decoder
This all-in-one utility combines base64 decode, base64 encoding, url decode, binary decoder, decode hex, and SHA-256 hashing in a single, streamlined interface. You can decode, encode, and hash data quickly, without sign-up, downloads, or server-side processing.
