How do I merge PDF files for free?

Open EdgeDocs' Merge PDF tool, add your files, arrange them in the order you want, and download the combined PDF. Free users get 3 downloads per day. All processing happens in your browser — no files are uploaded to any server.

Can I merge PDFs without uploading them to a server?

Yes. EdgeDocs merges PDFs entirely in your browser. Your files load locally, are combined locally, and the merged result is saved locally. There is no server involved in the process.

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

Free users can merge up to 3 files at a time. Pro subscribers can merge up to 50 files in a single operation.

Can I change the page order when merging?

Yes. After adding your files, you can drag them into any order before merging. The first file becomes the first pages of the combined document, and so on.

Will merging affect the quality of my PDFs?

No. Merging combines your files into one document without modifying or recompressing the content. The pages in the merged file are identical to the originals.

Why Merge PDFs Locally?

Most online merge tools upload every file to their servers — meaning your contracts, reports, and financial documents all pass through third-party infrastructure. EdgeDocs merges everything in your browser. Your files never leave your device, even temporarily.
