    "Fit to A4" and "keep original size" produce very different documents

    Fitting to A4 gives every page identical dimensions, centres each image, and pads the remainder with white. That is what you want for a document — a stack of receipts, a set of scanned pages — because it prints predictably and pages look consistent when scrolled.

    Keeping the original size makes each page exactly as large as its image in points. A 4000×3000 pixel photo becomes a 4000×3000 point page: roughly 55 inches wide. It looks fine on screen, because viewers scale to fit. It is a disaster to print, and a portfolio built this way will have pages of wildly varying sizes. Use it only when the images are already page-shaped, such as scans exported at a known dimension.

    Either way, JPEG images are embedded without re-encoding, so the PDF is as sharp as the photo. PNGs and other formats are converted to JPEG first, because PDF cannot embed PNG directly.

    How it works

    1. Drop in your images and drag them into order
    2. Choose whether to fit each image to an A4 page
    3. Click Build PDF and download
    Why nothing uploads. Every operation on this page happens inside your browser using JavaScript and WebAssembly. Your file is read into memory, processed, and offered back as a download. It is never transmitted. Disconnect from the internet after this page loads and the tool keeps working.

    Frequently asked questions

    Should I choose fit to A4 or keep original size?
    Fit to A4 for anything that will be printed, filed or read as a document — every page comes out the same size. Keep original size only for on-screen use where the images are already page-shaped.
    In what order do the images appear?
    In the order shown in the list, which you can change by dragging. Files do not sort alphabetically by default, because photo filenames rarely reflect the intended sequence.
    Are my photos recompressed?
    JPEGs are embedded as they are, with no quality loss. PNGs, WebP and other formats are converted to JPEG at 92% quality, because the PDF format cannot embed them directly.
    Can I add multiple images to one page?
    No — each image becomes its own page. For multi-image layouts, compose the page in an image editor first and add the result as a single image.
    What about transparent PNGs?
    Transparency is flattened onto white during conversion, since PDF pages have no alpha channel by default.
