Frequently Asked Questions

Encoding converts data into a specific format for safe transmission, while decoding reverses the process to restore the original data.
Base64 is commonly used in email attachments, data URIs, API communication, and anywhere binary data needs to be represented as text.
URLs cannot contain certain special characters, so URL encoding converts them into percent-encoded (%XX) format for safe transmission.
