When merging makes sense
Merging is useful when related documents belong together: a contract with its appendices, scanned pages saved as separate files, or several reports that need to be sent as one attachment.
Before you start, decide on the order. The merged file keeps every page of the first document, then every page of the second, and so on.
Merge PDFs with Pixuna
Open the Merge PDFs tool, choose or drop two or more PDFs, and use the arrows beside each file to set its position. Select Merge PDFs and download merged.pdf.
The files are read and combined in your browser tab. Pixuna does not upload them to a server.
What to check afterward
Open the result and scroll through it. Pages are copied into a new document, so bookmarks, form fields, and some interactive features from the originals may not be preserved.
Password-protected files cannot be merged until they are unlocked. If you know the password, use the Unlock PDF tool first.
- Check the page count against the sum of the originals.
- Check that rotated pages still appear the way you expect.
- Keep the original files until you are satisfied with the result.
Large files and limits
Everything happens in browser memory, so very large PDFs or many files at once can fail on devices with limited memory. If that happens, merge in smaller batches, then merge the results.
