    When merging PDFs is useful

    Merging is the quickest way to turn a pile of separate files into one document: a scanned contract with its annexes, a job application with certificates, or monthly statements combined into a single yearly file.

    Many upload forms accept only one PDF. Combining everything first means you can submit it in one go, and the recipient sees the pages in exactly the order you chose.

    Frequently asked questions

    Are my files uploaded anywhere?

    No. Everything happens inside your browser, on your own device. Your files are never sent to a server, and you can confirm that in your browser's network tab. Close the tab and they're gone.

    How do I change the order of the files?

    Drag a file up or down the list, or use the arrows beside it, before you merge. Files are joined from top to bottom.

    Will everything in my PDFs be kept?

    Page content, including text, images and links on the page, is preserved. Document-level extras such as bookmarks and fillable form fields may not carry over.

    Is there a file size limit?

    Each file can be up to 100 MB, and up to 300 MB in total. Because the work happens on your device, very large files depend on your available memory. A desktop browser handles them best.

    Can I use a password-protected PDF?

    Not directly. Use Unlock PDF on this site to remove the password (you need to know it), then add the unlocked copy here.
