Merge PDF

Combine several PDFs into one file, in the order shown below (drag to reorder).

    No files added yet

    Read the form fields already present in a PDF, fill them in and export. Files without fields cannot use this tool.

    All processing happens locally in your browser. Your files are never uploaded to any server.

    Open this tool

    Read the form fields already present in a PDF - text boxes, checkboxes and choice lists - fill them in right in the browser, then export. Great for application forms, surveys and fillable PDF templates.

    Field types come from the PDF itself; the tool only fills and exports. Files without fields cannot use this tool, and everything stays local.

    How to use it

    1. Add a PDF; its form fields are listed automatically.
    2. Type into text fields, tick checkboxes and pick choices.
    3. Click Start and download the filled PDF.

    Frequently asked questions

    Which field types are supported?
    Text boxes, checkboxes and choice lists - whatever the PDF defines.
    Can a scanned form be filled?
    No. Only real form fields inside the PDF are recognised; scanned or print-converted forms have no fields to fill.
    Are my files uploaded to a server?
    No. Everything runs in your browser and there is no upload endpoint, so the server never sees your content.
    How large a file can I use?
    Stay under about 100 MB and a few thousand pages. Speed and memory depend on your own device.
    Is it free? Do I need an account?
    It is completely free with no usage limit, and no sign-up or login is required.
    Does it work on phones?
    Yes, the layout is responsive. Large files and complex edits are easier on a desktop.
    Which browsers are supported?
    Any modern browser: Chrome, Edge, Firefox, Safari and their mobile versions.
    Does it work with scanned PDFs?
    Yes for page-level operations, which do not need a text layer. There is no OCR, so text cannot be pulled out of a scan.
