One private merge workspace
Combine PDFs in the order you can see.
Every added page appears in one workspace, so the final PDF follows the visible order instead of a hidden filename rule.
Which PDFs work here?
Ordinary PDFs work best. Passwords, signatures, forms, annotations, attachments, bookmarks, tagged structure, layers, and active content are left unchanged instead of being silently removed.
If a trusted document needs a simpler copy, keep the original and use your local viewer’s Print or Export to PDF option. Read the compatibility guide.
Add up to 20 source files
Pages from each supported PDF join the same grid. Add more files later without losing the arrangement already on screen.
Fix the order before merging
Drag cards or use the keyboard move controls, rotate sideways pages, and restore a removed page before creating the result.
Download only after Output Check
The finished merged PDF is reopened and compared with the expected visible page order before download is enabled.
