About the PDF Merger

Combining PDFs is one of those tasks that turns up constantly and has no business being difficult — a scanned contract that arrived as three separate files, a report where the appendix was exported on its own, an application that wants one attachment when you have five. The usual options are a desktop app you have to install or a website that asks you to upload documents you may not want to hand over.

This merger runs entirely in your browser. Add the files, drag them into the order you want, and download a single PDF. Nothing is uploaded, so there is no queue to wait in and no file size cap. The pages are copied across rather than re-rendered, which means the text stays as text and the images keep their original quality — the merged file is not a photograph of your documents.

Order matters, so the list is reorderable before you commit. If you are stitching together a scan that came out as separate files, check that the page counts add up to what you expect before downloading.

Frequently Asked Questions

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

No. The merging happens in your browser, so there is no server-side quota and no file size cap. The practical limit is your device's memory.

Does merging reduce quality?

No. Pages are copied from the source files rather than re-rendered, so text stays selectable and images keep their original resolution.

Can I change the order of the files?

Yes. Use the arrows next to each file to move it up or down. The merged PDF follows the order shown in the list.

Are my documents uploaded anywhere?

No. Everything happens locally in your browser. Nothing is transmitted, and the tool keeps working if you go offline after the page loads.
