Common questions
Merge PDF questions
How do I merge PDF files?+
Upload two or more PDFs, arrange them in the order you want, choose Merge, then preview or download the combined document.
Can I combine more than two PDFs?+
Yes. Add multiple PDF files to the workspace and combine them into one document in a single workflow.
Can I change the order before merging?+
Yes. Reorder files before merging so reports, appendices, invoices, or scanned pages appear in the sequence you need.
Can I preview PDFs before merging?+
Yes. You can preview uploaded PDFs and review the final combined document before downloading it.
Are my PDFs uploaded to Nexynto Tools?+
No. This tool reads and combines selected files in your browser, so they do not need to be uploaded to Nexynto Tools servers.
Does merging reduce PDF quality?+
The tool combines existing PDF pages and does not intentionally downsample their content. Use Compress PDF separately if file size is the priority.
Can I merge password-protected PDFs?+
An encrypted PDF may not open for merging. If you know the password, unlock the file first and then add it to the merger.
What limits the number or size of PDFs?+
Because processing is local, the practical limit depends on available browser memory and device performance.
What is interleaving?+
Interleaving alternates selected pages across files: page one from each file, then page two from each file, while keeping remaining pages from longer documents.
Can I merge PDF files on mobile?+
Yes. Choose PDFs available to your mobile browser, arrange them in the responsive workspace, and merge locally. Practical limits depend on the device’s available memory.
