DropJPG

Why DropJPG

No uploads, no accounts, no nonsense. It just converts.

🖼️

JPEG, PNG, GIF, TIFF, WebP, and Apple HEIC/HEIF — all to clean JPG via the built-in macOS engine.

📂

Drag a whole folder; it recurses into subfolders and handles everything at once.

🔢

Output lands in ~/Desktop/<name>/ numbered name_001.jpg, 002…

📐

Set a target width in pixels; aspect ratio is preserved automatically.

🔒

Everything runs locally. Your photos never leave your Mac. Originals are kept untouched.

🧭

No Dock clutter. Click the icon, drop, name, convert. The window stays on top.

설치 60초 · It's not signed with a paid Apple cert, so one extra step on first launch.

Grab DropJPG.dmg and drag DropJPG.app into Applications.

Double-click 먼저 실행 - 설치도우미.command inside the DMG, or run in Terminal:

xattr -dr com.apple.quarantine /Applications/DropJPG.app

Open DropJPG — its icon appears in the menu bar. Click it → 사진 변환 → drop your images.

왜 추가 단계? 개발자 인증서($99/년)가 없어 macOS가 차단합니다. 위 명령은 "인터넷에서 받음" 격리 속성만 제거합니다 — 그 외엔 아무것도 바꾸지 않습니다.
