Which encoding should I choose?
Base64 encodes UTF-8 bytes as printable characters; it is not encryption. Base64URL replaces URL-sensitive characters and omits padding (commonly used in JWTs). URL component encoding is best for individual query parameter values; full URL encoding preserves reserved separators such as /, ?, and &. These operations execute locally in your browser.
