    How it works

    1. Add at least two PDF files (up to 20 files, 25 MB each, 100 MB total).
    2. Drag files to set merge order. Each file’s pages stay together in that order.
    3. Click Merge PDF to combine them in your browser and download one file.

    Features

    • Reorder PDFs with drag-and-drop or arrow buttons before merging
    • Each page keeps its original size from the source PDF
    • Uses pdf-lib in your browser; files are not uploaded
    • Optional download filename; password-protected PDFs are rejected with a clear message

    Combine PDFs into one file in seconds

    Add two or more PDFs, put them in the right order, and click merge. The combined PDF keeps each page at its original size. It is ideal for job applications, rental packets, contracts, school assignments, and scanned paperwork that came out as separate files.

    Merging runs entirely in your browser using pdf-lib, so your documents are never uploaded. There is no watermark and no daily limit.

    Before you merge

    Password-protected PDFs need to be unlocked on your device first. If some of your pages are photos, convert them with JPG to PDF, then merge everything together. When the merged file is too large to email, shrink it with the PDF compressor.

    Merge PDF FAQ

    You need at least two PDFs. You can add up to 20 files per batch, with a 25 MB limit per file, 100 MB total, and 500 combined pages. These limits keep merging fast and reliable in the browser.

    Not in this version. The merged file contains the pages from each PDF in order, but document bookmarks from the originals are not carried over.

    No. Unlock or remove the password on your device first. The tool will tell you if a file is encrypted.

    No. Merging runs entirely in your browser. Your PDFs never leave your device.

    With Tools N Go, yes. Files are merged locally in your browser and never sent to our servers.

    No. The merged PDF contains only your pages, with no watermark or branding.
