Protocol Launcher

PDF Expert ​

PDF Expert is Readdle's PDF editor and reader for Mac, iPad, and iPhone. Protocol Launcher allows you to generate PDF Expert URL scheme links.

Usage ​

There are two ways to use this library:

  • On-Demand import from subpaths enables tree-shaking and keeps bundles small.
  • Full Import from the root package is convenient but includes all app modules.

Pick On-Demand for production builds; Full Import is fine for quick scripts or demos.

Select Installation Method

On-Demand
Recommended. Optimized for production.
Full Import
Convenient. Good for quick scripts.

Open Remote PDF ​

Save and open a direct PDF URL by adding the documented PDFE prefix.

On-Demand
ts
import { openRemotePdf } from 'protocol-launcher/pdf-expert'

const url = openRemotePdf({
  url: 'https://example.com/Guide.pdf',
})
Open Remote PDF in PDF Expert

Open File ​

Open a file stored in PDF Expert's Documents tab with the documented PDFEFILE:///Folder/Subfolder/File.pdf form.

On-Demand
ts
import { openFile } from 'protocol-launcher/pdf-expert'

const url = openFile({
  path: 'Folder/Subfolder/File.pdf',
})
Open File in PDF Expert

If folder names contain spaces, Readdle documents using %20; pass those escapes in path.

Open Synced File ​

Open a file kept in Synced folders with the documented pdfefile:///SyncedFolders/ static path.

On-Demand
ts
import { openSyncedFile } from 'protocol-launcher/pdf-expert'

const url = openSyncedFile({
  path: 'folder1/folder2/test.pdf',
})
Open Synced File in PDF Expert

Readdle notes that other app languages may require the translated version of the Synced folders part of the URL. This helper generates the documented English static path pdfefile:///SyncedFolders/.
