Merge PDF

Combine multiple PDF files into one, entirely in your browser.

Drag & drop PDF files here, or

Add 2 or more PDFs, up to 25 MB each. Processed entirely in your browser.

    How it works

    Each PDF you add is read and its pages are copied, in order, into one new PDF document — entirely inside your browser using an open-source PDF library. Files are never uploaded to a server.

    Example

    Add report-part1.pdf and report-part2.pdf, merge, and download a single combined PDF with all pages from both files in order.

    Frequently asked questions

    Can I merge password-protected PDFs?

    Encrypted or password-protected PDFs generally cannot be read by the browser-based library used here. Remove the password first using a PDF editor, then merge.

    Is there a limit on how many files I can merge?

    There's no hard limit, but very large or numerous PDFs may be slow to process depending on your device's memory.
