Is merging PDFs really free?

Yes. PDF Huddle's Merge PDF tool is free with no file limits, no signup, and no watermark.

Can I change the order the PDFs are combined in?

Yes. Use the up and down arrows next to each file to reorder them before merging — they'll appear in the final PDF in that exact order.

How many PDFs can I combine at once?

There's no fixed limit — add two files or twenty. Very large batches depend on your device's available memory, since everything runs locally.
