PDF Merger FAQ

Can I preview PDFs before merging?

Yes. The tool shows a small preview of the first page of each uploaded PDF.

Can I drag and drop PDF order?

Yes. Drag a file card and drop it above another file to change the merge order.

Can I still use buttons to reorder?

Yes. The up and down buttons are kept for users who prefer click-based ordering.

Are my PDFs uploaded?

No. The merge process runs in your browser using client-side PDF processing.

Why does a thumbnail fail?

Some locked, damaged or unusual PDFs may not render a preview, but standard PDFs should work normally.

Will this compress the PDF?

No. This tool merges PDFs. Use a PDF compressor when you need smaller file size.
