    About Merge PDF

    The free tool accepts up to 50 PDF files, subject to file-size and browser memory limits.

    Merging runs in the browser; the selected PDFs are not uploaded for this operation.

    Pages with different orientations or sizes can be placed in one output. Review the result, especially bookmarks and interactive fields, before sharing.

    Frequently Asked Questions

    Can I change the order before merging?

    Yes. Rearrange the file cards before starting, then inspect the downloaded PDF to confirm the sequence.

    How many PDFs can I combine?

    The free tool accepts up to 50 files. Large files may also be limited by your device’s available memory.

    Will image quality change?

    The tool copies pages into a new PDF rather than intentionally recompressing their images. Check the output if your file contains forms, bookmarks or unusual fonts.

    Are my files uploaded?

    No. This merge operation runs in your browser.
