Why merge PDF files?

Merging PDFs is useful for assignments, invoices, receipts, contracts, scanned documents, and building clean reports from multiple files. This tool keeps everything private by processing files directly inside your browser.

How to Use

Select the PDFs you want to combine, then review the order carefully. If the files need to appear in a different sequence, drag to reorder them before starting the merge. Remove anything unnecessary, click Merge PDF, and download the finished file. This is especially useful when you need to package report sections, scanned pages, contracts, invoices, or appendices into one attachment that is easier for another person to open and review.

FAQ

Does file order matter?

Yes. The merged PDF follows the order shown in the list, so reorder before you export.

Can I remove one file before merging?

Yes. Delete any file you do not want included, then continue with the remaining set.

Is it useful for scanned pages?

Very. Merging is a common final step after scanning multi-page documents as separate files.

Privacy Reassurance

The merge runs locally in the browser and does not require your documents to be stored on a remote system just to combine them. That keeps routine paperwork, class materials, and business PDFs in your direct control.
