Frequently Asked Questions (FAQs)
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It's commonly used to encode data for transmission over media designed to deal with text.
Base64 is used to encode binary data (images, files, etc.) into text format for: 1) Email attachments (MIME), 2) Data URLs in web pages, 3) Storing binary data in JSON/XML, 4) HTTP Basic Authentication, 5) Cryptographic operations.
No, Base64 is encoding, not encryption. It doesn't provide security or confidentiality. It's simply a way to represent binary data as text. Anyone can decode Base64 back to the original data.
Base64 uses 64 characters: A-Z (26), a-z (26), 0-9 (10), + and / (2). The = character is used for padding at the end if needed. There's also URL-safe Base64 that uses - and _ instead of + and /.
Base64 increases data size by approximately 33%. 3 bytes of binary data become 4 Base64 characters. For example, 1MB of binary data becomes about 1.33MB when Base64 encoded.
URL-safe Base64 replaces + with - and / with _ to make the string safe for use in URLs and filenames without requiring URL encoding. The padding = may also be omitted or replaced.
Yes, our tool supports file upload for Base64 encoding. You can drag and drop files or use the file selector to encode images, PDFs, documents, etc., to Base64 format.
Base64 decoding is the reverse process: converting Base64 encoded text back to its original binary form. Our tool supports both encoding (text/file to Base64) and decoding (Base64 to text/file).
Yes, Base64 can encode any binary data, including UTF-8 encoded text. When encoding text, it's first converted to bytes (UTF-8), then encoded to Base64. Decoding produces the original bytes.
1) Data URLs for images in CSS/HTML, 2) Storing small files in databases, 3) API responses with binary data, 4) JWT tokens, 5) Email attachments, 6) File uploads via JSON APIs.
