- Q: Can I download YouTube videos in 4K or 8K?
  A: Yes — when the YouTube source was uploaded in 4K (2160p) or 8K (4320p), we list it and merge the separate video and audio streams with ffmpeg on the server. If ffmpeg is not installed, we show a clear message instead of a broken file.

- Q: Do you merge video and audio for high quality?

Free text to emoji encryptor and decryptor. Turn secret messages into emoji strings with a password, then decrypt with the same password.

3. Decrypt with the same password to recover the original text.

- Q: Can someone crack it without the password?
  A: Not practically if you use a strong password. Wrong passwords fail decryption (authenticated AES-GCM).
- Q: Is emoji encryption safe for passwords and secrets?
