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, or use the ↑ and ↓ buttons on mobile.

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.
