Have you sent a ZIP file from your Mac to someone on Windows, only to find that the Japanese filenames appear garbled? STROBOFACTORY has released PKPassport for Mac , a Mac ZIP creation app focused on solving exactly that problem.
One Clear Focus: Filenames That Arrive Intact
ZIP files created in Mac Finder can display garbled Japanese filenames when opened on Windows, and may include Mac-only files such as .DS_Store. It is a small but persistent frustration for people exchanging files at work every day.
PKPassport does not try to pack in every possible feature. It focuses on delivering files correctly from Mac to Windows, without garbled filenames . Every part of that process is designed so you can check the result on screen before sending it.
Five Features
- Intact Filenames — Optimizes filename encoding for the recipient: CP932 for Japanese Windows, or UTF-8 for multilingual use, preventing garbled text
- Remove Mac-Specific Files — Automatically excludes .DS_Store, __MACOSX, and ._* files to keep the recipient's folders tidy
- Windows Preview — Check how filenames will appear on the recipient's Windows computer before you send them
- AES-256 Encryption — Strong password protection compatible with 7-Zip, WinRAR, and Keka. ZipCrypto is also available when compatibility is the priority
- Drag and Drop — Drop in files or folders. The ZIP is saved alongside the originals
Original Files Stay Intact. Everything Happens on Your Mac.
PKPassport never changes your original files; it simply creates a ZIP alongside them. All processing takes place on your Mac, and nothing is sent to a server, so you can use it with confidence.
Who It Is For
- Anyone who regularly sends ZIP files from a Mac to clients or business partners on Windows
- Anyone who has been told that their filenames are garbled
- Anyone who wants to keep files such as .DS_Store out of deliverables
- Anyone who wants to send password-protected ZIP files using AES-256 encryption
The Meaning Behind PK
Every ZIP file starts with the letters PK, the initials of ZIP inventor Phil Katz. The name PKPassport combines our wish to give files a passport from Mac to Windows without garbled text with respect for the person who made ZIP a universal format.
