How to Fix Cannot Find Cloud PDF Files When Uploading in Acrobat Reader
Question details
Users are unable to locate or select PDF files stored in the cloud when attempting to upload them from Acrobat Reader Mobile to an external website.

- Product
- Adobe Acrobat Reader
- Device & OS
- not provided
- Scenario
- Uploading a cloud-stored PDF document to an external work website via a mobile device browser.
- Observed behavior
- The cloud-stored PDF files are visible within the Acrobat Reader app but do not appear in the system file picker when browsing files to upload online.
Ensure your device has an active internet connection to download the cloud files and verify you have enough internal storage space available to save the documents locally.
Download Cloud PDFs to Internal Storage First
Bypass the file picker compatibility issue by saving the cloud document directly to your device's local storage before uploading.
Mobile web browsers rely on the operating system's native file picker to upload files. If a third-party app's cloud storage is not fully integrated with the system's file provider, those files will remain hidden during the upload process. Moving the file to internal storage acts as a reliable bridge.
Launch the Adobe Acrobat Reader app on your mobile device and navigate to the 'Files' tab to find your cloud-stored PDF.
Tap the three-dot menu icon next to the PDF you need to upload. Select 'Save a copy' or 'Download' and choose a folder on your device's internal storage, such as 'Downloads' or 'Documents'.
Return to your external work website in the browser, tap the website's upload button, and use the system file picker to select the downloaded PDF from your local device folder.
Easily Manage and Upload Cloud PDFs with WPS Office
WPS Office provides a highly integrated PDF reader and editor that flawlessly syncs with native system file managers. You can easily access, edit, and upload your cloud PDFs directly without encountering hidden file bugs during web uploads.
- 1. Install WPS Office: Download and install the free WPS Office app on your mobile device from the official app store.
- 2. Connect Your Cloud Services: Open WPS Office, navigate to the 'Cloud' or 'Open' tab, and log in to your preferred cloud storage service to access your documents.
- 3. Upload Files Without Restrictions: Because WPS Office registers seamlessly with your device's native file provider, you can easily browse and upload files directly from your cloud folders when prompted by external websites.

Frequently Asked Questions
Why can't external websites see my cloud files in Acrobat Reader?
Mobile operating systems use a universal system file picker to upload files to web browsers. If the cloud service integration within an app like Acrobat Reader doesn't expose those virtual files to the OS system picker, web browsers cannot fetch or display them.
Where are downloaded PDFs saved on my mobile device?
By default, files downloaded manually from cloud apps to internal storage are placed in the 'Downloads' or 'Documents' folder. You can access them using your device's native 'Files' or 'My Files' application.
Can I upload a PDF directly from Google Drive or iCloud instead of downloading it?
Yes. If your PDF is synced to native, system-integrated cloud apps like Google Drive (on Android) or iCloud Drive (on iOS), you can usually select those cloud drives directly from the website's upload file picker without downloading them manually first.
