How do I combine PDFs in the right order?

After uploading, drag and drop files to arrange them in your preferred sequence. The preview shows you exactly how the final document will be organized.

Can I combine PDFs with different page sizes?

Yes, the tool handles PDFs with different page sizes. Each page maintains its original dimensions in the combined document.

Will form fields work after combining?

Interactive form fields are preserved in the combined PDF. You can still fill out forms after the merge.

What's the maximum file size for combining?
