How to merge PDF files
- Drop your PDF files into the box above, or click it to browse and pick them.
- Put them in the order you want using the up and down arrows.
- Click Merge PDF and your combined file downloads on its own.
Everything runs on your device, so the merge is fast and your files stay private.
Is it safe to merge PDF files here?
Yes. Many free PDF sites upload your files to their own servers to do the work. This tool does not. Your PDFs are read and joined right inside your browser, so they are never uploaded, stored, or seen by anyone else. When you close the tab, nothing is left behind.
Can I reorder the files before merging?
Yes. After you add your files, each one shows up in a list. Use the up and down arrows to move a file higher or lower. The final PDF follows the exact order of the list, from top to bottom, so put the file you want first at the top.
Why is my merged PDF so large?
A merged PDF is about the size of all your files added together, because every page is kept at full quality. Files with many photos or scanned pages add up fast. If the final file is too big, run it through our Compress PDF tool to make it smaller.
Can I merge PDFs on my phone?
Yes. This tool works in any modern browser on iPhone, Android, tablets, and computers. There is nothing to install. Add your files the same way, tap Merge PDF, and the combined file saves to your device.
FAQs about Merge PDF
Are my PDF files uploaded anywhere?
No. The merge happens inside your browser on your own device. Your files never leave your computer or phone, and nothing is sent to a server.
How many PDFs can I merge at once?
As many as you like. There is no set limit and no file-size paywall. The only real limit is your device memory, since all the work is done locally.
Will merging lower the quality of my PDFs?
No. Every page is copied exactly as it is. Text stays sharp and images keep their resolution, because the files are joined without being squeezed or re-saved.
Does the merged file keep bookmarks and links?
Links inside your documents are kept, but the bookmark outline (the clickable contents list in the sidebar) is not carried over yet. All pages, text, and images stay exactly as they were.
Is Merge PDF really free?
Yes. It is completely free with no sign-up, no watermark, and no file-size limit. Everything powerful, nothing paid.
