Base64 Encoder/Decoder - Data encoding and decoding

Base64 Encoder/Decoder is a professional tool for encoding and decoding text, files and binary data in Base64 format. Base64 is an encoding standard that represents binary data as an ASCII string using 64 characters (AZ, az, 0-9, +, /). Our tool supports various encoding modes, including URL-safe encoding, time wrap settings, and automatic encoding detection.

What is Base64?

• Coding standard: Base64 is an encoding scheme that converts binary data into text format
• 64 characters: Uses 64 characters: AZ (26), az (26), 0-9 (10), + and / (2)
• Padding: The symbol = can be used to align the length of the line
• Security: It is not encryption, but only data encoding
• Compatibility: It is supported by all modern programming languages and systems

Using Base64

• Email attachments: Encoding files for transmission via email (MIME)
• Web Development: Embedding images in CSS and HTML (data URLs)
• API and web services: Transmission of binary data via JSON and XML
• Databases: Storage of binary data in text fields
• Configuration files: Coding of passwords and keys in the settings
• Logging in: Safe logging of binary data
• Cryptography: Representation of hashes and signatures in text form
• File systems: File transfer via text protocols

Functions of our tool

• Encoding in Base64: Conversion of any text or file to Base64
• Decoding from Base64: Restoration of original data from Base64 strings
• URL-safe encoding: Using the symbols - and _ instead of + and /
• Adjustment of time transfers: Addition or deletion of time periods as a result
• Encoding support: UTF-8, ASCII, Latin-1 and automatic definition
• File Operations: Loading and downloading files in Base64 format
• Statistics: Detailed information about the size of the data before and after encoding
• Security: Data processing locally, without transfer to the server

Advantages of use

• Versatility: Works with any type of data: text, images, documents
• Compatibility: The standard is supported by all systems and languages
• Simplicity: Easy to use and integrate into projects
• Reliability: Time-tested coding standard
• Efficiency: Fast processing of even large volumes of data
• Security: The data is processed locally in the browser

Usage Recommendations

• Use URL-safe encoding to transmit data via URLs
• Add line breaks for long Base64 lines in email and documents
• Check text encoding before encoding for correct result
• Do not use Base64 to store large files - the size increases by ~33%
• Remember that Base64 is not encryption - the data is easily decoded
• Use for temporary encoding or transmission via text protocols
• Check the validity of the Base64 string before decoding
• Keep backup copies of the original data before encoding
