Combine Files Into One PDF

The paperwork somebody asks you for is never all one kind of file. A receipt is a photograph, the contract came out of a signing service as a PDF, and the rest are screenshots. Drop the lot in, drag them into the order you want, and get one document. Pictures become pages, PDFs contribute their pages unchanged, and page numbers can be added at the foot so the person receiving it can refer to page nine. It all happens in your browser, which matters when the bundle is a claim or a visa application.

    Frequently asked questions

    Are my files uploaded?

    No. Your browser reads every file, turns the pictures into pages and writes one new document, all in the tab. The site’s security policy sets connect-src ‘none’, so the browser blocks network requests from these pages, so nothing could be sent even if the code tried. People combine files to submit a claim, an application or an expense report, and those are the last things that should pass through somebody else’s server.

    Can it take Word or Excel files?

    No, and it says so by name rather than accepting them and producing something approximate. A .docx is a folder of XML that means nothing until a layout engine decides where every line breaks; the browser has no such engine, and a guess at your layout would be worse than no answer. Export to PDF from Word or Google Docs first, then drop the PDF in here.

    What happens to the PDFs I add?

    Their pages are copied object by object, exactly as they were, with the fonts and images they use. Nothing is re-encoded and nothing is re-laid-out, so a contract comes out the same size and the same sharpness it went in.

    And what happens to the pictures?

    Each one becomes a single page. It is scaled to fit the page size you chose, with a small margin, and saved as a JPEG inside the document, at most 2400 pixels on the long side. That is roughly 200 dots per inch on A4, which reads well on screen and prints legibly. If you need to choose the quality yourself, the picture-to-PDF tool does that and nothing else.

    Why is the page number always at the bottom in the middle?

    Because that is where a bundle somebody has to refer to wants it, and because the number is drawn in Helvetica, one of the few fonts every PDF reader carries. If you need it in a corner, in a particular size, or with your own wording, use the page numbers and watermark tool on the finished file.

    Does the order I drop them in matter?

    Only as a starting point. The list shows the order the document will be in, and the arrows move any item up or down before you press Combine. Get it wrong and nothing is lost: change the order and press it again.
