How do I merge multiple PDF files?

To merge PDF files, simply upload the documents you want to combine, arrange them in your preferred order by dragging and dropping, then click the merge button. Our PDF merger will combine all uploaded PDFs into a single document that you can download immediately. The entire merge PDF process takes just seconds.

Is there a limit on the number of PDFs I can merge?

No, there is no limit on how many PDF files you can merge with our tool. Unlike other PDF mergers that restrict you to 2-5 files, you can merge 10, 20, 50, or even more PDFs in a single operation. The tool handles large merge jobs efficiently, combining all your documents into one comprehensive PDF file.

Are my PDF files secure when I merge them?

Yes, absolutely. When you merge PDF files using our tool, everything processes locally in your browser. Your PDFs never upload to external servers, and no copies remain after you download the merged document. This merge PDF approach guarantees complete privacy and security for sensitive documents.

Can I rearrange the order of PDFs before merging?

Yes! After uploading PDF files to merge, you can drag and drop them into any order you want. The visual interface shows thumbnails of each document, making it easy to organize PDFs before you merge them. Reorder documents as many times as needed until the sequence is exactly right for your merged PDF.

What's the file size limit when I merge PDF documents?

Our PDF merger can handle files of any size because processing happens in your browser. Whether you need to merge small PDF documents or large files containing hundreds of pages, the tool processes them efficiently. Total merged file size depends only on your browser's memory capacity.

Will the merged PDF maintain the original quality?

Yes! When you merge PDF files with our tool, all documents combine without any compression, quality loss, or formatting changes. The merged PDF maintains the same resolution, clarity, and layout as the original files. Text stays sharp, images remain clear, and all formatting elements preserve perfectly in the final merged document.

How do I merge PDF files in a specific order?

After uploading the PDFs you want to merge, simply drag and drop them in the workspace to set your desired order. Each document shows a preview thumbnail. Arrange them from top to bottom in the sequence you want pages to appear in the merged PDF. The first file becomes the first pages, the second file follows, and so on.

Can I merge PDF files from different sources?

Yes, you can merge PDF files regardless of where they originated. Combine PDFs created in different applications, scanned documents, downloaded files, or PDFs you generated yourself. The merge PDF tool handles all standard PDF formats and combines them into one unified document, preserving all content from each source file.

Does merging PDFs add watermarks to my document?

No. When you merge PDF files with our tool, the output document contains no watermarks, branding, or added text. Your merged PDF stays completely clean and professional, containing only the content from the original files you combined. We never add watermarks to merged documents.
