Formula and explanation

The engine opens each PDF locally, copies its pages in the displayed order and creates a new document.

Pages are not rendered as images, so their visual quality is preserved.

Password-protected documents must be unlocked before they can be merged.

Frequently asked questions

Are PDFs uploaded?

No. Merging takes place in your browser's memory.

Is quality lost?

Pages are copied rather than rasterized, preserving their contents.

Can I reorder files?

Yes, by dragging and dropping or with the move buttons.
