Frequently asked questions
How many PDFs can I merge?
There is no fixed limit. Very large batches (hundreds of files or many gigabytes) depend on your device memory — merging in smaller groups is more reliable on phones.
How do I change the order?
Use the up and down arrows next to each file. The files are merged from top to bottom.
Do links and comments survive the merge?
Page content, links and annotations are kept. Bookmarks (the outline panel) from the original files are not carried over.
Can I combine files that have a password?
Yes — enter each file's password when asked. Files that only block printing or copying open automatically.
Can I merge private files like bank statements?
Yes. The files are joined inside this browser tab and never sent anywhere, so statements, invoices and scans stay on your device.
