Why merge PDFs online?

Combining PDF files is one of the most common document tasks — bundling invoices for an expense report, joining chapters into one file, or pulling exhibits together for a filing. EasyPDFViewer merges PDFs directly in your browser using the open-source pdf-lib library, so your documents never leave your device.

How EasyPDFViewer compares

Most free online PDF mergers (Adobe, SmallPDF, iLovePDF) upload your file to their servers and cap free usage at 1-2 tasks per day. EasyPDFViewer runs client-side, has no daily limit, and never sees your file. If you need to merge sensitive documents — contracts, medical records, tax filings — a browser-only tool is safer by design.

Frequently asked questions

Is this PDF merger really free?

Yes. Merging PDFs on EasyPDFViewer is 100% free, with no signup and no watermarks on the output.

Are my files uploaded anywhere?

No. The merge runs entirely in your browser using pdf-lib. Your PDFs never leave your device.

How many PDF files can I merge at once?

There is no hard limit on the number of files. Each individual file must be under 100 MB.

Will the merged PDF keep bookmarks and forms?

Page content is preserved. Some interactive form fields and bookmarks may be flattened during merge.

Can I merge password-protected PDFs?

No. Please use our Unlock PDF tool first to remove the password from any PDFs you own, then merge.

Does it work on iPhone and Android?

Yes. The tool works in any modern browser — Chrome, Safari, Edge, Firefox — on desktop and mobile.
