Hider scrambles your image pixels using a password. The result looks like random noise — enter the same password to restore instantly. No cloud. No account. No internet required. What makes it different: - Wrong password shows no error, just a different scramble. By design. - Two-layer encryption: encrypt twice with different passwords. - File size stays the same after encryption. Limitation: Google Photos and similar platforms recompress images, breaking encryption. Free. Windows only.
