FAQs about Merge PDF Online
How many PDFs can I merge?
You can select multiple PDFs, but the practical limit depends on file size and available browser memory on your device.
Are the PDFs uploaded to your server?
The merge is performed in your browser for supported PDF files. The selected documents are not uploaded to our website server for processing.
Does file order matter?
Yes. Select the PDFs in the order you want them combined. The tool appends the pages from each selected file in that sequence.
Why will an encrypted PDF not merge?
Password-protected, encrypted or damaged PDFs may not be readable by the browser PDF library. Use an unlocked copy that you are authorized to process.
