💡

A common scenario

You need to combine a few exported PDF reports on your MacBook to email to a client, and Preview does not have a built-in merge tool.

🔒

Why privacy matters here

Native Mac apps and cloud tools both involve uploading the file somewhere. DukPdf keeps the merge entirely in your browser, so the documents never leave your Mac.

Merge PDF on Mac — questions

Can I merge PDF on Mac without installing software?

Yes. DukPdf runs in any modern browser on macOS, including Safari, Chrome, Firefox, and Arc. There is nothing to install and no extension to add.

Does the merge work in Safari?

Yes. DukPdf is fully tested in Safari on macOS. Drag-and-drop upload, drag-to-reorder thumbnails, and download all work the same as in Chrome or Firefox.

Is there a file size limit on Mac?

There is no hard limit — the tool is constrained only by your Mac's available memory. Files up to several hundred megabytes work on typical M-series hardware.

Will merging change my PDFs?

No. Merging only rearranges pages and copies streams. Output pages are byte-identical to the input, so image quality, fonts, and metadata are preserved.
