Can I merge a PDF with more than 1000 pages?

Yes. ClonyPDF does not enforce a page count limit. You can merge textbooks, manuscripts, or large reports seamlessly.

Does merging large files take a long time?

It depends on your internet speed, but our server-side processing ensures that once uploaded, the merging happens in seconds regardless of page count.

What if the final merged file is too big?

If your merged file is too heavy to email, use our built-in PDF Compressor to reduce the file size without losing pages.

Merge PDF No Page Limit (Combine 1000+ Pages)

Most online mergers have a hidden "Wall"—they stop working if your files exceed 50 or 100 pages. ClonyPDF is built for heavy documents. Whether you are combining a 500-page thesis or 10 years of bank statements, we don't count the pages.

Tips for Merging Massive Files

💡 Pro Tip: Is the file too big?
If you merge 1000 pages, the file size might become huge (e.g., 200MB). We recommend using our Compress PDF tool after merging to make it easier to share via email.
