Frequently Asked Questions

What is Base64 encoding?
Base64 represents binary data using 64 ASCII characters (A-Z, a-z, 0-9, +, /). It's commonly used in email attachments, data URLs, and API payloads.
Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone can decode it without a key. Never use it to protect sensitive information.
Can I encode files?
Yes. Upload any file to encode it to Base64. You can also paste a Base64 string and decode it to download as a file.
