- Device & OS

- Scenario
- Attempting to share a large collection of before-and-after work images saved as PDFs, but unsure how to handle a batch of more than 12 files at once.
- Observed behavior
- The user is looking for the correct method to upload multiple files for sharing or to combine more than 12 PDFs into a single document without hitting processing limits.
Before combining or uploading your PDFs, verify that your total file size does not exceed your cloud storage limits and that all document pages are oriented correctly.
Combine More Than 12 PDFs Using a Desktop PDF Editor
Merging multiple PDFs into a single file before uploading is the most efficient way to share a large portfolio without overwhelming the recipient.
Online cloud services sometimes restrict the number of files you can process at once (e.g., maximum 12 or 20 files per merge). By using a desktop PDF application, you can bypass these limits, combine dozens of files into one neat document, and then upload a single file to the cloud.
Launch your desktop PDF software (such as Adobe Acrobat or WPS Office).
Navigate to the 'Tools' menu and select 'Combine Files' or 'Merge PDF'.
Click 'Add Files' and select all the 12+ PDF images you wish to include in your portfolio. You can drag and drop them to rearrange their order.
Click the 'Combine' or 'Merge' button. Once the process is complete, save the consolidated document to your computer.
Log into your Document Cloud account and upload the newly created single PDF file to share it via a link.

Upload and Share a Folder via Cloud Web Interface
If you prefer to keep the files separate rather than merging them, you can upload them to a dedicated folder and share the folder link.
Merge and Share Unlimited PDFs with WPS Office
WPS Office provides powerful PDF editing and merging tools along with seamless built-in cloud storage. You can easily combine dozens of PDF images into a single professional portfolio and share it instantly.
- 1. Open WPS PDF: Launch WPS Office and click on the 'PDF' tab from the main dashboard.
- 2. Access the Merge Tool: Click on 'Merge PDF' located in the top toolbar.
- 3. Add and Arrange Files: Import your 12+ PDF files. Drag and drop the thumbnails to arrange them in the correct before-and-after sequence.
- 4. Merge and Share via Cloud: Click 'Merge' to create your single portfolio document. Save the file to WPS Cloud to instantly generate a shareable web link.

Frequently Asked Questions
Is there a limit to how many PDFs I can upload to Document Cloud at once?
While general cloud storage allows you to upload hundreds of files as long as you stay within your total storage quota, some specific online web-based merging tools may limit you to 12 or 20 files per operation. Desktop applications generally do not have this restriction.
Why should I combine my PDF portfolio instead of sharing individual files?
Combining files into a single continuous PDF document makes it much easier for clients to view your work sequentially. It provides a smoother presentation experience compared to forcing the recipient to click through or download multiple individual files.
Can I arrange the order of my PDFs before merging them?
Yes. Whether you use desktop PDF editors like WPS Office or online merge tools, you will be provided with an interface to drag and drop your uploaded files into the exact order you want before executing the merge.
What is the maximum file size for merging PDFs online?
Online PDF tools often have file size limits (such as 50MB or 100MB per file or batch) to prevent server overload. If your portfolio contains high-resolution images exceeding this limit, using a desktop PDF software is highly recommended.
