Base64 Encoder / Decoder vs Hash Generator
Both tools are 100% free, browser-based, and require no signup. Here is how they differ so you can pick the right one for your task.
Base64 Encoder / Decoder
Free Base64 encoder and decoder. Encode text or files to Base64 and decode Base64 strings back to text. Supports file to data URI encoding. No signup required.
Use Base64 →Hash Generator
Free hash generator. Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 cryptographic hashes from text or files. Verify file integrity and checksums instantly in your browser. No upload, no signup.

When to Use Each Tool
- →Select 'Encode' to convert text or files to Base64, or 'Decode' to convert Base64 back to text.
- →Type or paste text into the input area. For files, switch to File mode and select any file from your device.
- →The encoded or decoded output appears instantly below the input.
- →Select MD5, SHA-1, SHA-256, SHA-384, or SHA-512 from the algorithm buttons.
- →Type or paste text in the input area, or click "Choose File" to hash a local file.
- →The hash appears instantly. Click "Copy" to copy it to your clipboard.
Frequently Asked Questions
Base64 is a binary-to-text encoding scheme that represents binary data using 64 printable ASCII characters (A–Z, a–z, 0–9, +, /). It is used to safely transmit binary data (images, files) through text-based protocols like HTTP headers, email (MIME), and JSON.
Base64 encodes 3 bytes of binary data into 4 ASCII characters, making the output approximately 33% larger than the original. This size increase is the trade-off for making binary data safe to include in text formats.
A hash function takes any input (text or file) and produces a fixed-length string of characters (the hash or digest). The same input always produces the same output. Changing even one character of the input completely changes the hash. Hashes are one-way — you cannot recover the original input from the hash.
SHA-256 (Secure Hash Algorithm 256-bit) is used for verifying file integrity, in blockchain and cryptocurrency (Bitcoin uses SHA-256), digital signatures, SSL/TLS certificates, and password hashing (when combined with a salt). It produces a 64-character hex string and is considered cryptographically secure.
