How to merge PDFs

1. Drop your PDF files into the box above (or tap “choose files”). 2. Drag the cards (or use the arrow buttons) to set the order. 3. Press “Merge PDF” and download the result.

Nothing is re-printed or re-compressed

GustKit copies the original pages into the new document with pdf-lib, so text stays selectable and searchable, vector graphics stay sharp and images keep their original quality. The merged file is usually the size of the inputs added together.

Good to know

Password-protected PDFs must be unlocked first. Form fields are copied as they are, but interactive forms that rely on JavaScript may need to be re-checked after merging.

Frequently asked questions

Is there a limit on how many PDFs I can merge?

There is no fixed count. The practical limit is your device's memory; most phones handle a few hundred pages comfortably, and computers far more.

Are my PDFs uploaded?

No. The files are read and combined by JavaScript running in this tab. You can even disconnect from the internet after the page loads.

Can I remove or rotate pages while merging?

Merge first, then open the result in our Rotate & organize PDF tool to rotate, delete or reorder individual pages.
