How to Merge PDF Files Online
Learn how to combine PDF documents in the right order, check the final file, and avoid common merging mistakes.
Step-by-step instructions
1. Prepare the files
Give the documents clear names and decide their reading order before combining them. If a document contains private information, check how your chosen tool handles files before using it.
2. Add documents in sequence
Open the PDF merger, choose the documents, and arrange them so the final PDF follows the intended sequence.
3. Create and inspect the result
Merge the documents, open the downloaded file, and confirm page count, order, orientation, and readability.

Why does my merged PDF have pages in the wrong order?
The order usually follows the sequence shown in the merger. Reorder the source files and try again.
Will merging PDFs reduce file size?
Not necessarily. Combining files can increase the total size; compression is a separate operation.
