Base32, Base64, and Hex Decoder Interface
Instant Decoded Output Results
How to Use the Base32 and Hex Decoder
Decoding with our tool is simple and takes just seconds:
- Select Format: Choose Base32, Base64, or Hex from the tabs above
- Paste Your Text: Enter your encoded string in the input box
- Click Decode: Hit the decode button for instant conversion
- Copy Result: Use the copy button to save your decoded text
Our base32 decode function handles RFC 4648 standard encoding automatically. The hexadecimal decoder supports all hex formats including color codes and byte strings. For Base64, we handle both standard and URL-safe variants.
What is Base32 Encoding and Decoding?
Base32 decode is the process of converting Base32-encoded text back to its original format. Base32 uses 32 ASCII characters (A-Z and 2-7) to represent binary data, making it ideal for case-insensitive systems.
Common Uses for Base32:
- TOTP authentication tokens (Google Authenticator, Microsoft Authenticator)
- File encoding in distributed systems (IPFS, Blockchain)
- QR code data encoding for mobile applications
- Case-insensitive unique identifiers in databases
- Email systems and DNS records (DKIM, SPF)
- API keys and tokens in modern web applications
Unlike Base64 which uses 64 characters, Base32's limited character set makes it more reliable when case sensitivity matters or when avoiding ambiguous characters like 0/O or 1/l/I. Our base32 decoder supports all modern Base32 variants.
Hexadecimal Decoder: Converting Hex to Text
Our hex decoder converts hexadecimal (base-16) strings to readable text. Hexadecimal uses 16 characters (0-9 and A-F) to represent binary data in a compact, human-readable format.
Common Hex Decoding Scenarios:
- Network traffic analysis: Decode hexdump from Wireshark or tcpdump
- File headers: Identify file types from hex signatures (Magic Bytes)
- Color codes: Convert hex color values (#RRGGBB) to RGB
- Memory dumps: Decode debugging output from applications
- Binary to hex decoder: Convert binary data to readable text
- Blockchain transactions: Decode Ethereum/Smart Contract data
- Game development: Parse hex-based game save files
To decode hexadecimal successfully, ensure your hex string has an even number of characters (each byte = 2 hex digits). Our hex to text decoder automatically removes spaces and handles various input formats including 0x-prefixed strings.
Frequently Asked Questions
How do I decode Base32 strings?
To base32 decode, paste your encoded string in the input box above, select "Base32" from the format tabs, and click "Decode". The decoded result appears instantly. Our decoder supports all Base32 variants including Crockford's Base32. Try the Base32 decoder →
Can I decode hexadecimal to text?
Yes! Our hex to text decoder converts hexadecimal strings instantly. Select "Hex" from the tabs, paste your hex string (like 48656c6c6f or 0x48656c6c6f), and click decode. We support both uppercase and lowercase hex. See hex examples →
Is this decoder free to use?
Absolutely! Our base64 decoder, hex decoder, and base32 tools are 100% free with no registration, limits, or hidden fees. We're committed to providing free tools.
Does it work on mobile devices?
Yes, our decoder is fully optimized for mobile phones and tablets. Works perfectly on iOS, Android, and all modern browsers with touch-optimized interface.
What if my decoded hex looks scrambled?
If your hex decode output appears scrambled, ensure your hex string has an even number of characters and only contains 0-9 and A-F. Remove any spaces, 0x prefixes, or special characters first. Learn more about hex decoding →
What's the difference between Base32 and Base64?
Base32 uses 32 characters (A-Z, 2-7) and is case-insensitive, while Base64 uses 64 characters (A-Z, a-z, 0-9, +, /) and is case-sensitive. Base32 produces longer strings but works better in case-insensitive systems and QR codes.
Does this support URL-safe Base64?
Yes! Our decoder automatically handles URL-safe Base64 (with - and _ instead of + and /). Just paste your URL-safe Base64 string and select Base64 format.
Can I decode large files?
For security and performance, we recommend decoding text strings up to 10MB. For larger files, consider desktop applications. Our web tool is optimized for typical encoding/decoding tasks.
