How to Convert JPG to PDF

Images into one PDF

Photos live as JPGs, but paperwork lives as PDFs. A form that wants one PDF, not twenty photos. An application that accepts a single document. A receipt, a certificate, or a set of scans that has to travel as one file. Converting images to PDF is the bridge between the two, and it is a job worth doing properly — because a PDF made badly is worse than the photos you started with.

This tool builds one PDF from your images: one image per page, in the order you add them. You can add up to 50 images at once — JPG, PNG, or WebP — up to 100 MB in total. That covers a whole set of receipts, a full photo album for an application, or every page of a document you photographed. The result is a single PDF called images.pdf, ready to send or upload.

Two choices shape the result, and both are simple. The first is page size: A4 or US Letter. Pick the one your form or your printer expects — in most of the world that is A4, in the United States it is Letter. The second is how each image sits on its page: Fit inside page shows the whole image, with margins where the image and the page do not match in shape; Fill page crops the edges of the image so it covers the whole page with no margins. Fit is the safe choice when nothing may be cut off — a document, a certificate, a form. Fill is the right choice when the image should cover the page edge to edge, like a photo page. A tall phone photo on a wide page will always have margins under Fit, and will always lose its top and bottom under Fill; that is the trade-off, and it is yours to choose.

There are honest limits to know. Each image is saved into the PDF as a JPEG at high quality, and very large photos are scaled down so the longest side is 2000 pixels. On an A4 page that is still sharp — a printed page does not need more — but the PDF is not a pixel-perfect archive of a 50-megapixel original. If you need the full-resolution photo, keep the JPGs. PNG transparency is also flattened onto white, because the images are converted to JPEG, and JPEG cannot store transparency. A logo with a transparent background will show a white box behind it; that is expected, not a bug.

Order matters, and it is the order you add the images. If you are building a document from photographed pages, add them in reading order — page 1 first, page 2 second — and check the result before sending it. The tool does not read text or detect page numbers, so it cannot fix a wrong order for you. If you add a photo by mistake, remove it and run the conversion again; each run takes seconds, and there is no daily limit.

Practical tips. Photograph documents straight on, in good light, with the page filling the frame — a tilted photo becomes a tilted PDF page, and the tool will not straighten it for you. If a photo is sideways, rotate it before converting; the tool builds pages in the orientation the image has. And if the PDF has to be small enough to email, remember that 50 large photos make a large PDF: compress the images first with the Compress Image tool if the file must fit a size limit, or split the set into two PDFs.

Everything runs in your browser. Your photos never go to a server, so personal pictures stay personal. Drop up to 50 images, pick a page size and a fit, and download one clean PDF.
