Whether you're assembling a job application, joining monthly statements or putting chapters of a report together, one file is simpler to send and store. RIZONI TOOLS merges your PDFs while keeping every page intact — text, images and links stay as they were.

Merging happens in your browser, so private documents are not uploaded to any server.

What is kept when you merge PDFs?

Each page is copied as it is, including text, images, vector graphics and its original size and orientation. Pages of different sizes can be combined in one document.

Document-level features such as bookmarks (outlines) and interactive form fields from the separate files may not be carried over in every case, because they belong to the original documents rather than to individual pages.

Merging tips

Name your files with numbers (01, 02, 03…) before adding them — it makes checking the order much easier. If one file needs rotating, fix it first with the PDF Rotator.

If the combined file is too large to send, run it through the PDF Compressor afterwards.

Privacy and security

Frequently asked questions

How many PDFs can I merge at once?

You can merge up to 20 files of up to 50 MB each in one go. To combine more, merge them in groups and then merge the results.

Does merging reduce quality?

No. Pages are copied without re-compression, so the merged PDF looks exactly like the originals.

Can I merge password-protected PDFs?

Files that require a password to open can't be merged. Remove the password first, then add the file again.

Can I change the page order inside a file?

The merger arranges whole files. To pick or reorder individual pages, use the PDF Page Extractor on the merged file.

Are my files uploaded?

No. Everything happens in your browser on your own device.
