Text Encryptor

Easily encrypt and encode text using Base64 or AES. Instantly protect your text for privacy, secure sharing, and data protection. All processing is done locally in your browser for maximum privacy and speed.

Text Encryptor: Secure, Encode, and Protect Your Text Instantly

Text Encryptor by 2025 PDF Station is a modern, browser-based tool that empowers you to encrypt, encode, and decode your text with ease. Whether you’re a developer, student, security enthusiast, or simply someone who values privacy, this tool is designed to make text protection accessible and reliable for everyone.

How Does Text Encryptor Work?

Text Encryptor offers two robust methods for transforming your text:

  • Base64 Encoding: Quickly convert any text into a Base64 string, making it safe for transmission, storage, or embedding in web pages and APIs. Base64 is not encryption, but it’s a widely used encoding scheme for data serialization and transfer.
  • AES Encryption: Secure your text with Advanced Encryption Standard (AES), a powerful symmetric encryption algorithm trusted worldwide. AES requires a secret key, ensuring that only those with the correct key can decrypt and read your message.

Key Features & Advantages

  • All Processing is Local: Your text and keys never leave your device. Everything happens instantly in your browser for maximum privacy and speed.
  • Dual Functionality: Encrypt and encode, then immediately decrypt or decode to verify your results—no need for separate tools.
  • Simple, Intuitive UI: Clean layout, clear instructions, and responsive design make it easy for anyone to use, on any device.
  • Free & Unlimited: No registration, no fees, no limits. Use the tool as often as you need.
  • Supports All Languages: Unicode support means you can encrypt and encode text in any language, including emojis and special symbols.
  • Mobile Friendly: Enjoy a seamless experience on desktop, tablet, or smartphone.

Real-World Use Cases

  • Developers: Secure API keys, configuration files, or sensitive data before sharing or deploying code. Encode data for web forms, URLs, or JSON payloads.
  • Writers & Journalists: Protect drafts, notes, or confidential information before sending or storing online.
  • Students & Educators: Learn about cryptography, encoding, and data security through hands-on experimentation.
  • Business Professionals: Safeguard business communications, contracts, or client data with strong encryption.
  • Security Researchers: Test, demonstrate, or teach encryption and encoding concepts in a risk-free environment.

Step-by-Step: How to Use Text Encryptor

  1. Enter or paste your text in the input area.
  2. Choose your method: Base64 for encoding, AES for encryption (enter your secret key).
  3. Click Encrypt/Encode Text to transform your input.
  4. Copy the result for use in emails, code, or secure storage.
  5. To verify, use the Decrypt/Decode section: paste the result, select the method, enter the key if needed, and click Decrypt/Decode Text.

Privacy & Security: Our Commitment

  • No Uploads, Ever: Your data is never sent to a server. All encryption, decryption, encoding, and decoding are performed locally in your browser.
  • Open Standards: We use trusted, browser-native cryptography (Web Crypto API) for AES, and standard Base64 encoding/decoding for maximum compatibility.
  • Transparency: You can inspect the code or use the tool offline for peace of mind.

Technical Details

  • Base64: Converts text to a safe, ASCII string. Useful for embedding binary data in text formats, or for simple obfuscation.
  • AES (CBC mode, 256-bit key): Encrypts your text with a user-supplied key. The tool automatically generates a random IV (initialization vector) for each encryption, and combines it with the ciphertext for easy decryption.
  • Key Handling: For AES, your key is padded or trimmed to 32 bytes (256 bits) for strong security. Never share your key with anyone you don’t trust.
  • Browser Requirements: Works in all modern browsers with JavaScript enabled. No plugins or extensions required.

Tips for Best Results

  • Always remember your AES key—without it, decryption is impossible.
  • For Base64, remember that it’s encoding, not encryption. Don’t use it for sensitive data protection.
  • Test your encryption and decryption using the built-in verification feature before sharing or storing important data.
  • Bookmark this tool for quick access whenever you need to secure or encode text.

Frequently Asked Questions
