Drop files or a whole folder on LockDrop and it saves a zip locked with your password, right beside the originals. Everything runs on your Mac. Nothing is uploaded. No account, no subscription. What you get • Two kinds of lock. Strong (AES 256) for anything private. Standard for a zip that opens with a double click on any Mac or Windows. One switch chooses. • A password maker. One click makes a long random password and copies it. You type it twice and LockDrop checks they match, so a typo can't lock you out. • Folders, empty folders and hidden files all go in. Zips over 4 GB work. • Photos, videos and other files that are already compressed are stored as they are, so it stays quick. • A progress bar, and a Stop button that cancels cleanly. • Drop on the window or on the Dock icon. Your password is never saved. LockDrop forgets it when you quit. Good to know The lock hides what is inside, not the file names. A lost password can't be recovered by anyone. To open a Strong (AES 256) zip, the person needs a free app such as Keka or The Unarchiver on a Mac, or 7-Zip on Windows. Mac's own Archive Utility can't open them. Standard zips open with a double click, but that older lock is weak, so keep it for casual use. You'll need a Mac with Apple Silicon (M1 or newer) running macOS 13 or later. It isn't a signed, notarised app from the Mac App Store. The first time you open it, macOS may ask you to confirm you trust it. Right click the app, choose Open, then click Open. You only do that once.
