Frequently Asked Questions

How do I select specific pages from a PDF?

In each file's Pages field, enter a comma-separated list with ranges. Examples: 1-5, 2, 4, 6, or 1-3, 7, 10-12. Leave it empty to include every page.

Are my PDFs uploaded to a server?

No. The merger runs entirely in your browser using JavaScript. Your files never touch any server, so they remain completely private.

Can I rotate pages before merging?

Yes. Pick 90°, 180°, or 270° from the rotation dropdown next to each file. The rotation is applied to all included pages from that file.

How do I reorder files?

Drag the handle (⋮⋮) on any file to a new position, use the ↑ and ↓ buttons, or the quick-sort buttons (A→Z, Z→A, Reverse).

Can I add page numbers?

Yes. Tick Add page numbers to output and the merged PDF will be numbered sequentially at the bottom center of each page.

What if my PDF is password-protected?

Encrypted PDFs cannot be processed in-browser. Unlock them first using a PDF reader, then upload them here.

Is there a file size limit?

No artificial limit — only your device's available memory. Most laptops and phones handle hundreds of pages without issue.
