Frequently asked questions

How do I combine multiple PDFs into one?
Open the Merge tool, add each PDF in turn, arrange the pages in the order you want, and download the single merged file.
Is there a limit on how many PDFs I can merge?
No upload limit — because merging happens in your browser, you can combine several files without a per-file cap or a watermark.
Does merging upload my files to a server?
Everything runs in your browser — your file never leaves your device and is never uploaded to a server. It is completely free, with no watermark and no sign-up needed.
Can I reorder the pages before merging?
Yes. Drag pages in the thumbnail rail to arrange them exactly how you want before you download.
