PDF Merger

Free online PDF merger · runs in your browser

Drop PDF files here, or click to choose them

Up to 20 files, 100 MB total. They merge in the order listed below. Processed in your browser — never uploaded.

    The merged file keeps each document's pages in order. Page sizes, fonts, and images are preserved as they were. Encrypted or damaged PDFs cannot be merged here.

    How to merge PDFs

    Drop two or more PDFs on the tool above. They appear in a list — use the up and down arrows to arrange them in the order you want, remove any you do not need, then press “Merge PDFs”. The merged file downloads as one PDF. Nothing is uploaded; the merge happens in your browser.

    What stays the same, and what changes

    Every page keeps its size, fonts, images, and content. Merging only stitches documents together — it does not reformat anything. A landscape page stays landscape; an A4 page stays A4. Page numbers printed inside your documents do not change, so if each file numbered its own pages from 1, the merged file will repeat those numbers. Bookmarks and links inside the original files are usually kept, but this is not guaranteed for every PDF.

    Common uses

    The most common use is a single application file. A job application with a CV, a cover letter, and certificates becomes one document that a recruiter can open once. The same applies to visa applications, tax filings, and school submissions — anywhere a portal asks for “one PDF” and you have several. It is also handy for combining scanned chapters of a book or monthly statements into one archive file.

    Limits to know

    You can merge up to 20 files, 100 MB in total. Larger jobs can run out of browser memory, so split them: merge the first ten, then merge that result with the rest. Encrypted or damaged PDFs cannot be merged — remove the password or repair the file first. And note that merging never makes a file smaller; if the result is too big to send, compress it afterwards with the PDF Compressor on this site.

    A note on order

    Check the order before you merge. It is easy to mix up two similar files — a 2024 statement and a 2025 statement, for example. The list on the page shows each file's name and size, and the arrows let you fix the order in seconds. Once merged, reordering means starting over.
