I don't know, but assume that youâd be concerned if a website kept a copy and be fine if it didn't. So why use an online service for a conversion that could be done offline? OS X The default image viewer is Preview, which can export to PDF. If you do it regularly, use Automator or AppleScript, and a drop folder, service, workflow or applet. It will be way faster than uploading and downloading! Windows The default image editor is (I think) Photos; it can âprintâ to a PDF. Shouldn't be hard to automate.
JPEGs are an amazing data format. They are perfect for use with the native PDF app, Preview. If you use Preview to send images into the digital photo editing programs, you will encounter problems because of this PDF format. OS X Preview recognizes the size of the image file, but it cannot actually display it in the app in the same way it would a PNG, JPEG, or GIF image; at that point in a PDF, the image file size is irrelevant. Preview does allow you to export a picture at two different sizes, so if you need a larger version that is not necessarily 300 pixels/inch, then that would be more work for you to do yourself. For example, if you had a 1024)768 image, and you exported it at 300 pixels/inch, then Preview will show two images. The size of a picture, however, is not necessarily the.
