This tool puts a set of pictures into one PDF, one image per page — photographed receipts that have to be filed as a single document, scanned pages from a phone, screenshots that need to be sent as a report, artwork that has to arrive in a printable format. You can keep each page exactly the shape of its image, or lay the images out on A4 or Letter pages with a margin, which is what most printers and submission portals expect. The conversion is done entirely in the browser, so photographs of your documents stay on your device.
No. Each image is read from your device and embedded into a PDF that is assembled in the page. Nothing is sent to a server, which is worth knowing when the images are photographs of documents or identification.
Choose A4 or Letter when the PDF will be printed or submitted to a form that expects standard pages. Choose "Fit to image" for screenshots, artwork and anything that should fill the page edge to edge with no white border.
JPG and PNG files are embedded exactly as they are, so no quality is lost. Other formats — WebP, AVIF, GIF, BMP — are converted to high-quality JPEG first, because the PDF format itself cannot carry them.
Yes. With orientation set to "Auto", each page turns to match its image, so a landscape photograph gets a landscape page instead of being shrunk to fit a portrait one. You can also force every page to one orientation.
No, each image gets its own page. That keeps the result predictable and printable; for contact sheets or collages, arrange the images in an image editor first and convert the finished layout here.
