Good to know
Merging is useful when you need to send one clean file instead of many: a job application with a CV and certificates, an invoice with its receipts, or scanned pages from different sources. Files are combined in the exact order shown in the list, so check the order before you press the button.
Frequently asked questions
Is there a limit on the number of files?
There is no fixed limit. Very large files depend on your device memory, so merge in smaller batches if your browser becomes slow.
Are my files uploaded anywhere?
No. The merge happens inside your browser and your documents never leave your device.
Why did my file fail to merge?
The PDF may be damaged or protected with a password. Remove the password first and try again.
