Base64 Utility
Convert between plain text and Base64 encoding. Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. It's commonly used when there's a need to encode binary data that needs to be stored and transferred over media that are designed to deal with ASCII text.
Pro Tip: Double-click any text area to quickly copy its content.
Convert your text to Base64 encoding - useful for embedding binary data in places that only accept text.
Common Uses of Base64
- Embedding images directly in HTML/CSS
- Storing binary data in JSON
- Email attachments (MIME)
- Encoding credentials for Basic Authentication
- Data URIs for web resources
2FA Code Generator
Generate time-based one-time passwords (TOTP) for two-factor authentication. This tool helps you generate verification codes using your 2FA secret key without needing a mobile authenticator app.
Important: This tool is meant for personal use when you need to access your accounts but don't have your phone or authenticator app available.
About Two-Factor Authentication
Two-factor authentication adds an extra layer of security to your accounts by requiring:
- Something you know (your password)
- Something you have (a device that generates a temporary code)
TOTP codes change every 30 seconds, making them much more secure than static passwords. Even if someone learns your password, they still can't access your account without the temporary code.
Facebook ID Finder
Extract the numeric ID from any Facebook URL. This tool automatically detects and extracts IDs from profiles, groups, pages, or posts, which can be useful for API interactions, custom applications, or analytics.
Why Facebook IDs Matter
Facebook's numeric IDs are permanent identifiers that remain consistent even when names or usernames change:
- Profile IDs: Permanent identifiers for user accounts
- Group IDs: Allow reliable identification of groups even if names change
- Page IDs: Essential for businesses and developers
- Post IDs: Enable specific targeting of content for sharing or analysis
- Essential for Facebook API development and third-party integrations
Facebook Live Status Checker
Check if Facebook user IDs are still active or have been deactivated/deleted. This tool helps you verify multiple Facebook accounts at once and separate the active from inactive ones.
About Facebook UID Status Checking
Understanding Facebook UID status can be important for:
- Database maintenance and cleanup of old entries
- Verifying if accounts are still active before API operations
- Checking if banned or problematic accounts have been deactivated
- Cleaning up contact lists and outdated integrations
