About Base64 Encoding
Base64 encoding is a method of converting binary or text data into a sequence of printable ASCII characters. It's commonly used when you need to transmit data through systems that only support ASCII text, such as:
Data Transfer
- • Email attachments
- • URL encoding
- • API requests
- • Data embedding
Web Development
- • Data URIs
- • Image embedding
- • Font encoding
- • SVG in CSS
Storage
- • Database storage
- • File encoding
- • Data backup
- • Text serialization
Frequently Asked Questions
What is Base64 encoding used for?
Base64 encoding is used to convert binary or text data into a format that can be safely transmitted over systems that only handle ASCII text. It's commonly used in email attachments, data URIs, and when embedding binary data in XML or JSON.
Will Base64 encoding change my data?
Base64 encoding is a reversible process - when decoded, you'll get back exactly the same data you started with. However, the encoded data will be about 33% larger than the original due to the encoding overhead.
Are there any size limitations?
The tool supports CSV files up to 10MB in size. For larger files, consider splitting them into smaller chunks or using server-side processing tools. Remember that Base64 encoding increases the data size by approximately 33%.
Is my data secure?
All processing happens entirely in your browser - no data is sent to any server. Base64 encoding is not encryption and doesn't provide security, it's simply a way to represent binary data in ASCII format.
