Why did my PDF pages get mixed up?

This usually happens due to 'Name Sorting' (Doc10 comes before Doc2) or 'Date Sorting'. Renaming files with '01_', '02_' prefixes fixes this.

How to merge PDFs in a specific order?

Upload your files to ClonyPDF, then drag and drop the thumbnails to arrange them visually. The final file will follow exactly what you see on screen.

Merge PDF Without Rearranging Pages

It is frustrating when you upload "Chapter 1", "Chapter 2", and "Chapter 3", but the merged file comes out as "1, 3, 2". This guide explains why tools shuffle pages and how to stop it.

⚠️ Common Symptoms

Pages appear in reverse order (Z-A instead of A-Z).
Middle chapters jump to the end.
Scanned documents reorder based on "Date Modified" instead of name.

Why Does the Order Change?

🔤	Auto-Sorting: Many tools automatically sort files Alphabetically (A-Z). If your files are named "Doc1", "Doc10", "Doc2", "Doc10" will come before "Doc2".
📅	Metadata Conflict: If you upload scanned files, some tools sort by "Creation Date" hidden inside the file code.
🖱️	Drag Errors: Sometimes, dragging a group of files uploads them in random order based on which file your mouse was holding.

How to Lock the Correct Sequence

Rename Files First: Add numbers like "01_Intro", "02_Body", "03_End". This forces almost any tool to respect the order.

Use Manual Sort: After uploading to ClonyPDF, use our drag-and-drop interface to visually confirm the order before clicking Merge.

Merge Once: Don't merge "Batch A" then "Batch B". Upload all files together for a consistent sequence.

Merge With Total Control

Drag, drop, and lock your page order exactly how you want it.
