Merge PDF Files in Seconds No Sign-up. No Email. Totally Free.

Absolutely! Our free PDF merger handles files with different page sizes and orientations with ease. When you merge PDFs, each page keeps its original dimensions and orientation in your final document. This comes in handy when you're combining documents like landscape spreadsheets with portrait reports into a single, professional-looking file.

You can merge PDF documents without any strict limits! Our free tool lets you combine multiple files in one go. While there's no hard cap on the number of PDFs you can merge, your device and browser might affect performance with extremely large batches. For the smoothest experience when merging 20+ files, try processing them in smaller groups of 10-15 files at a time.

Not at all! Unlike many other tools that compress your content, our PDF merger preserves the original quality of all your files. Your images stay sharp, text remains crisp, and vector graphics keep their precision. Think of it like combining physical documents without any photocopying – you get all the original quality in your merged PDF.

Your files never leave your computer when you merge PDFs with our tool. We process everything directly in your browser, not on our servers. We can't see, access, or store your documents – it's like having a PDF merging app installed locally, but without the hassle of downloads or installations. This client-side approach gives you complete privacy, making our tool perfect for sensitive documents like financial reports or confidential contracts.

Currently, our free PDF merger doesn't support combining password-protected or encrypted files. You'll need to unlock your PDFs before merging them. If you need to merge secure documents, first remove the password protection using the owner password, then combine them with our tool. We're working on adding support for protected files in future updates!

Good news! When you merge PDF files with our tool, interactive elements like form fields, buttons, and links stay intact in your combined document. However, if two of your original PDFs have form fields with identical names, you might see some conflicts in the final file. For documents with complex interactive features, we recommend testing by merging a couple of pages first to check the results.

While our main PDF merger combines complete documents, you can still merge specific pages with a quick two-step process. First, use our free PDF splitter tool to extract exactly the pages you want. Then, merge those extracted pages using our PDF merger. This gives you complete control over which pages appear in your final document – perfect for creating custom reports or presentations from multiple sources.

Yes! After you merge PDF files with our tool, your combined document remains fully editable with any standard PDF editor. Text, images, and other content keep all their original properties and can be modified just like before. This makes our free merger perfect for creating working documents that you'll need to update later – merge now, edit anytime!
