Put several pictures into a single PDF in the order you choose. It all happens in your browser, so your photos and scans stay private.

    Everything you enter is processed in your browser and is never sent to a server.

    How to use

    1. Drop your pictures onto the box or choose files. Use the arrows to put them in the order you want, and the cross to remove one.
    2. Choose the page size (A4, Letter, or the size of each picture), the orientation and the margin.
    3. Press Create PDF. The file downloads with one picture on each page.

    Examples

    Three photos, A4, automatic orientation
    → A PDF with 3 pages, one photo per page
    A photo that is wider than it is tall gets a landscape A4 page, and a tall one gets a portrait page.
    One 800×400 pixel picture, page size same as the picture, no margin
    → A page of 600×300 points (about 8.3×4.2 inches)
    Pixels are turned into points at 96 pixels per inch.
    A 1600×900 picture, A4, margin 20 mm
    → A landscape A4 page with the picture centered inside the margins

    How it works

    Each picture becomes one page. The open-source pdf-lib library, in its maintained @cantoo fork, writes the file. A picture is placed in the centre of the page, as large as it fits inside the margins, with its proportions kept. With the page size set to the size of the picture, the page is the picture’s size plus the margin, and one pixel counts as 0.75 points. A4 is 595×842 points and Letter is 612×792.

    JPG and PNG pictures go in as they are. Other formats, and JPGs that carry a rotation note, are first redrawn by the browser, and the result is stored as a PNG, or as a JPG for a rotated JPG. HEIC photos are read with the libheif decoder, which loads only when needed.

    The page layout and the reading of the rotation note are tested, and so is the PDF itself: a file made from pictures is opened again to check its page count.

    Frequently asked questions

    Are my pictures uploaded?
    No. The PDF is built in your browser and downloaded directly. The pictures never leave your device.
    Does it make the PDF bigger than the pictures?
    A JPG is stored in the PDF as it is, without being compressed again, so the file is about as large as the JPGs together. A PNG, WebP or other picture is stored as a lossless PNG, which can be larger. If the file is too big, convert the pictures to JPG first with the image converter.
    Why are my phone photos not sideways?
    Phones store photos sideways and note the rotation inside the file. The tool reads that note and turns the picture upright before it goes into the PDF.
    Can I put several pictures on one page?
    Not at the moment. Each picture gets its own page. To combine PDFs afterwards, use the PDF organizer.
    What are the limits?
    Up to 100 pictures at a time, each up to 50 million pixels. SVG files are drawn at a sharp size and put on a white page.
    Is the PDF searchable?
    No. The PDF holds pictures, not text, so a scanned page cannot be searched or copied from.
