PDF Merger FAQ

Quick answers about merging multiple PDF files, page ordering, quality preservation, and file size limits.

How do I merge PDF files online?

Upload two or more PDF files using drag-and-drop or the file browser. Reorder them by dragging thumbnails into the sequence you want. Click Merge and download the combined PDF — the entire process takes seconds.

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

Free users can merge files up to 10 MB total. Paid plans support up to 500 MB and unlimited file count. There is no hard cap on the number of individual files you can combine in a single merge.

Will merging PDFs change the quality or layout?

No. Merging is a lossless operation that concatenates pages without re-encoding. Text, images, fonts, links, bookmarks, and form fields are preserved exactly as they appear in the originals.

Can I rearrange the page order before merging?

Yes. After uploading, drag and drop file thumbnails to set the order. The final merged PDF follows your custom sequence from top to bottom.

Can I merge password-protected PDFs?

PDFs with a user password (open password) need to be unlocked before uploading. PDFs with only an owner password (edit restriction) can usually be merged without issues.

Does the merged PDF keep bookmarks and links?

Yes. Internal links, bookmarks, and table-of-contents entries from each source PDF are carried over into the merged document so navigation still works.

Is my data secure during the merge?

All files are uploaded over an encrypted HTTPS connection. Processing happens on our server and files are automatically deleted after the merge completes. We never access, store, or share your documents.

Do I need to install any software?

No. The merger runs entirely in your browser and works on Windows, Mac, Linux, Chromebook, and mobile devices. No plugins or desktop software required.

Can I merge PDFs on my phone?

Yes. The tool is fully responsive and works on iPhone, Android, and tablet browsers. Upload files from your device, reorder them, merge, and download — all from the mobile browser.

What file formats can I merge?

This tool accepts PDF files only. If you need to combine images or Word documents into a PDF, convert them to PDF first using our converter tools, then merge the resulting PDFs here.
