How to merge PDFs.

  1. Add your PDF files.

    Select at least two PDFs. Files are checked for a PDF header, readable structure, and supported page count before they enter the list.

  2. Arrange pages and files.

    Preview pages and use the arrows to reorder pages within each PDF. Then move whole PDFs into the order you want; the merged output follows both orders.

  3. Merge and download.

    Choose Merge PDFs. When processing finishes, download the new PDF and check it in your preferred PDF reader.

Supported input

Choose PDF files up to 20 MB each. You can merge up to 10 files, 50 MB combined, and 500 pages total. Empty, damaged, password-protected, or unsupported PDFs are rejected with a recovery message.

Browser processing

The PDF bytes are read into temporary browser memory. A local PDF renderer creates page previews, and a local Web Worker creates the merged file. Neither process uploads your document to EkkySoft, sends it to analytics, or saves it in browser storage. Normal page resources still load from this website.

Document features

The tool copies page content without rasterizing pages. Interactive forms, comments or other annotations, bookmarks, digital signatures, and some metadata may not carry over. Encrypted PDFs are not supported; check the merged file before relying on it.

Troubleshooting.

Why was my file rejected?

The file must be non-empty, have a PDF filename or PDF media type, and contain a readable PDF document. Export a fresh copy if the file is damaged. Password-protected files are not supported.

Can I change individual page order?

Yes. Use each page preview's up and down buttons to arrange pages inside that PDF. Then use the file-list controls to arrange the PDFs. Pages remain grouped by their source PDF.

Will forms, signatures, or bookmarks be preserved?

Not necessarily. The tool copies PDF pages into a new file; some interactive form data, annotations, bookmarks, signatures, and metadata can be lost. Use a PDF editor designed to preserve those features when they matter.

Why did processing stop?

PDF parsing uses device memory. This tool limits file size and page count, but browser or device memory can still constrain unusually complex documents. Try fewer or smaller files.
