In your browser
- Open JPG to PDF and drop in your images. PNG, WebP and other formats work too.
- Put them in order with the arrows. Each image becomes one page.
- Pick a page size (the image's own size, A4 or US Letter) and a margin, then click Create PDF.
JPG images are placed in the PDF exactly as they are, so there is no loss of quality, and nothing is uploaded.
On an iPhone or iPad
In the Files app, select the images, then tap and hold one of them (or tap the … menu) and choose Create PDF. For photos in the Photos app, save them to Files first.
On Windows
Select the images in File Explorer, right-click and choose Print. Pick Microsoft Print to PDF as the printer, choose a layout and click Print; Windows asks where to save the PDF.
On a Mac
Select the images in Finder and open them together in Preview. Put the thumbnails in order, select them all, then choose File → Print and use Save as PDF in the PDF menu at the bottom of the print window.
If the PDF is too large
Phone photos are big. Run the finished file through Compress PDF, or shrink the photos first with Compress JPG.
How sharp the pages need to be
An A4 page is 8.27 by 11.69 inches. At 300 dots per inch, the usual print quality, that is 2480 × 3508 pixels. A 12-megapixel phone photo, 4032 pixels wide, has more detail than an A4 page can show: about 490 pixels per inch across the width. Resizing photos to about 2500 pixels on the long side before converting makes the PDF much smaller with no visible difference in print.
Common problems
- A page came out sideways. Phones often store photos sideways with a note saying how to rotate them. Rotate the image itself before converting if a page appears turned.
- iPhone photos will not load. iPhones save photos as HEIC, which many programs cannot read. Convert them to JPG first, or change the camera setting to Most Compatible.
- A photographed document looks grey and uneven. Shadows and room light make the paper look grey. A scanner app, or raising the contrast, gives clean white pages.
- Portrait and landscape pages are mixed. With a fixed page size, landscape photos are shrunk to fit a portrait page. Use the image's own size for each page, or rotate them.
