Files stay on your device. Add more files at any time before merging.

Your PDFs will appear here in the order they will be combined.

    Blank = all pages. Example: 1-3, 5. Selections keep your entered order; repeated pages are included again.

    How to use this tool

    Add PDF files, then use Move up and Move down to choose their order. Leave Pages blank to include every page, or enter a selection such as 1-3, 5. Select Merge PDFs and download the result. You can also select pages from a single PDF. Your original files stay unchanged.

    Good to know

    Up to 20 files, 20 MiB per file, 30 MiB combined and 500 output pages. A 30-second timeout and Cancel keep processing recoverable. Password-protected PDFs, detected signatures and interactive forms are rejected. This tool copies pages without rasterizing or deliberately recompressing images. Bookmarks, attachments, document metadata, accessibility tags and PDF/A compliance are not preserved; internal links and annotations may change. It is not a redaction or metadata-cleaning tool. Keep originals and check the downloaded PDF.

    PDF merging questions

    Are my PDFs uploaded?

    No. The PDF files and selected pages are processed in a local browser worker. No account or server upload is needed. Standard site page analytics does not receive file contents or file names.

    Can I combine PDFs in a different order?

    Yes. Move files up or down before merging. Within a file, enter page selections in the order you want: 3, 1-2 places page 3 first. Blank includes every page.

    Can I extract pages from one PDF?

    Yes. Add one file and choose a range such as 2-4. The download contains those selected pages as a new PDF. This is page copying, not secure redaction of hidden information.

    Will merging reduce quality or file size?

    Pages are copied without rendering them to images, so this is not an image-quality slider or PDF compressor. The result can be larger or smaller because its PDF structure is rewritten. Review complex documents after export.
