Security Notes

• Base64 is not encryption — it's just encoding
• Never store passwords or secrets in Base64
• Data URLs bypass CORS but increase document size
• Always validate & sanitize before decoding untrusted data

Performance Tips

• Base64 increases size by ~33% — use wisely
• For images <5KB, data URLs reduce HTTP requests
• Large Base64 strings block the main thread
• Use base64url for URLs, cookies, filenames
