Frequently asked questions

How do I merge PDF files for free?

Drop your PDF files into the tool above, arrange them in the order you want, and click Merge. The combined PDF downloads instantly. No account, no payment, no watermarks — it just works.

Is it safe to merge PDFs online?

Yes. Your files are processed directly in your browser and never uploaded to our servers. We physically cannot see your documents. Once you close the tab, they are gone.

Does merging PDFs reduce quality?

No. Merging combines the pages from each PDF into a single file without recompressing images or altering content. Your merged document keeps the exact same quality as the originals.

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

You can merge up to 20 PDF files at a time, each up to 100 MB. For most everyday tasks — combining reports, receipts, or scans — that covers it. If you need to merge more, run the tool twice and merge the results.

Can I merge PDFs on my phone?

Yes. The merge tool works on any device with a modern browser — iPhone, Android, iPad, laptop, desktop. No app to install.

Can I choose the order of pages in the merged PDF?

Absolutely. After uploading, drag the files into the order you want. The merged PDF follows that sequence exactly. You can rearrange as many times as you like before clicking Merge.
