Convert JPG to PDF online, free

Converting JPG to PDF means taking one or more images in JPG format and placing them, one per page, inside a single PDF document. It's useful for sending photos as a formal document, grouping several images into one file, or turning phone photos of documents into something easy to print or archive.

This tool checks the actual content of each file (not just its name or extension) to make sure it's a valid JPG/JPEG before converting it; if an image isn't, it tells you clearly instead of generating a corrupted PDF. The images are embedded as-is, without recompressing or re-encoding them, so they don't lose any additional quality in the process: the resulting PDF will weigh roughly the same as the sum of the original images.

Each page of the PDF matches the actual size and aspect ratio of its image — a portrait photo produces a portrait page, and a landscape one, a landscape page — assuming a resolution of 96 dots per inch unless the image itself specifies a different resolution in its JFIF header. Keep in mind that this tool doesn't apply EXIF rotation: if a phone photo only looks upright thanks to that metadata, it will appear rotated the same way in the final PDF.

Since everything happens in your own browser, your photos are never uploaded to a server. Speed depends only on your device, which is why the number of images and the combined size per conversion are limited, so the tool runs smoothly in any browser.
