About Base64 Conversion
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. Our Base64 Converter tool allows you to easily encode text or files to Base64, and decode Base64 back to its original form. This is particularly useful for embedding binary data in places that only support text, such as JSON, XML, or email attachments.
All processing is done entirely in your browser, ensuring your data remains private and secure. No information is uploaded to any server, making this tool both fast and privacy-friendly.
Frequently Asked Questions
What is Base64 encoding and why is it used?
Base64 encoding is a method of converting binary data into a text format using 64 ASCII characters. It's commonly used when binary data needs to be stored or transferred in environments that only support text, such as embedding images in HTML/CSS, including binary data in JSON, or sending attachments in email.
Can I encode and decode files with this tool?
Yes, our Base64 Converter supports both text and file encoding/decoding. You can upload files (images, documents, etc.) to encode them to Base64, or paste Base64 strings to decode them back to files. This is useful for working with file data in text-based formats.
Is there a size limit for encoding/decoding?
Since all processing is done in your browser, very large files may cause performance issues. For best results, we recommend files under 10MB. Text encoding/decoding is generally faster and can handle larger amounts of data.
Is my data secure when using this tool?
Yes, all processing is done entirely in your browser. Your data is never uploaded to any server, ensuring complete privacy and security. We have no access to your information at any point during the encoding or decoding process.
What's the difference between standard Base64 and URL-safe Base64?
Standard Base64 uses the characters A-Z, a-z, 0-9, +, and / with = for padding. URL-safe Base64 replaces + with - and / with _ to make the encoded string safe for use in URLs and filenames. Our tool supports both formats for both encoding and decoding.
