Troubleshooting
Why is the order not matching my arrangement?
In the Merge PDF window, drag the cards up or down to rearrange and then click merge again. If dragging doesn’t update the position, release the mouse and try again, or remove that file and add it back.
Why does the merged file fail to open or show an error?
This may be caused by a corrupted file, oversized file, or password protection. Try uploading each original file individually to check. If it fails to open, fix or remove the password first, then merge again.
Why is merging sometimes fast and sometimes slow?
Speed depends on the number of pages, resolution, and your device’s performance (since this tool runs in your browser). Scanned images with high resolution or many files may take longer to process.
Why doesn’t the highlight frame appear or align correctly?
On some browsers, the highlight frame may not display or may be slightly off. This is only a visual issue and does not affect rearranging. You can still reorder files as usual.
Why does my device freeze or lag when merging many files?
Try merging fewer files at a time, use a computer instead of a mobile device, or close other memory-intensive tabs or apps to avoid overloading your device.
Frequently Asked Questions (FAQ)
What file types are supported?
Currently, this tool only supports PDF files. For other formats, please convert them to PDF first before merging.
Can password-protected PDFs be merged?
No, password-protected PDFs cannot be merged. You must remove the password before merging.
Is there a daily usage limit?
No, there are no limits. You can use it for free as much as you want. However, very large or numerous files may process slower depending on your device.
Can I merge only specific pages?
This version automatically merges all pages of the selected files. Selecting specific page ranges is not supported yet.
How is this different from PDF compression?
Merging PDFs combines multiple files into one, while PDF compression reduces the file size without changing the number of pages.
