DropShelf - Technical Support

🚀 Quick Start

Launch DropShelf

After first launch, DropShelf stays in the menu bar. Click the menu bar icon to open the shelf panel, or use the global hotkey ⌥Space to quickly invoke it.

Grant Accessibility Permission

To support global hotkeys and drag monitoring, DropShelf needs Accessibility permission. Click "Go to System Settings" in the prompt, then enable DropShelf in System Settings → Privacy & Security → Accessibility.

Drag Files to Shelf

When dragging files in Finder or other apps, DropShelf auto-shows a floating panel. Drop files onto the panel to store them. You can also trigger via screen edge hot zones.

Organize & Use Files

In the shelf you can: right-click to rename, batch compress to ZIP, convert image formats, merge PDFs, press Space to preview, then drag files to target.

❓ FAQ

Shelf panel doesn't auto-appear when dragging

⚠ Permission

Drag monitoring requires Accessibility permission. Please check:

Go to System Settings → Privacy & Security → Accessibility
Confirm DropShelf is listed and enabled
If enabled but not working, uncheck and recheck, then restart DropShelf

Global hotkey ⌥Space doesn't open panel

⚠ Hotkey Conflict

Default hotkey is ⌥Space (Option+Space), may conflict with other apps. Try:

Check if other apps use ⌥Space (e.g. Spotlight alternatives)
Change to a different hotkey in DropShelf settings
Confirm Accessibility permission is granted

Files disappeared after reboot

⚠ Storage

DropShelf uses Security-Scoped Bookmarks to persist file references. If files disappeared:

Original files were moved or deleted — the shelf saves references, not copies
Files were from external devices (USB drive, external HDD) that are disconnected
Persistence data directory was accidentally cleaned (at ~/Library/Application Support/DropShelf/)

Image conversion format/quality issues

⚠ Usage

DropShelf supports conversion between PNG, JPEG, HEIC, WebP, TIFF formats. Note:

JPEG is lossy — converting from lossless formats (PNG/TIFF) results in smaller files but slight quality loss
HEIC format requires native macOS support, usually no issues on macOS 13+
Converted files are saved in the same directory as the original

PDF merge order is wrong?

ℹ Feature

PDFs merge in shelf display order. To adjust the order:

Arrange files in the desired order in the shelf first
Select files to merge, right-click and choose "Merge PDF"
Merged file will be named "Merged_DateTime.pdf"

How to switch app language?

ℹ Feature

DropShelf supports 39 languages. Default follows system language, or switch manually in settings:

Settings → Language → Interface Language

Some interfaces need to be reopened after switching.

Does DropShelf upload my files?

🔒 Privacy

Absolutely not. DropShelf is a fully offline local tool that does not connect to any remote servers. All file operations (compression, conversion, renaming, merging) are performed locally on your Mac. Your file data will never leave your computer.
