Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data as an ASCII string. It is commonly used to embed images in HTML/CSS, transmit data in URLs, and encode email attachments.
Is Base64 encoding the same as encryption?
No. Base64 is an encoding, not encryption. Anyone can decode Base64 data without a key. It is used for data transport, not security.
What is URL-safe Base64?
URL-safe Base64 replaces the + and / characters with - and _, and removes padding (=). This makes the encoded string safe to use in URLs and filenames without additional escaping.
Can I encode files to Base64?
Yes. This tool supports encoding both text and files to Base64. You can use it to convert images, documents, or any binary file into a Base64 string for embedding in code.
