How to merge PDF files in a chosen order
Combine complete PDFs while keeping an original copy and checking the resulting page order.
Walkthrough
- Select two or more unencrypted PDFs. Each selected file must be within the displayed 50 MB limit.
- Use the up/down arrows to order whole files. The interface does not delete or reorder individual pages.
- Click Merge PDF and open the downloaded result. Compare its total pages with the sum of the inputs.
Open the relevant Tooldit tool.
What to check before relying on the result
Page sizes can differ within the output. Original text and images are copied, but document-level bookmarks, form relationships and digital signatures may change.
Troubleshooting
Unlock an encrypted input with authorization first. Use Split PDF to extract wanted pages before merging. If a large batch fails, try a smaller batch without discarding originals.
Privacy and output checks
Tooldit file and text tools process their contents locally. Optional page analytics is separate, and SEO and contact tools use network services. Read the Privacy Policy. Keep original files and inspect the output before sharing it. Examples in this guide are instructions, not measured performance tests.
