Fit to image, or a standard page size
Fit to image makes each PDF page exactly the size of the photo that fills it — nothing cropped, nothing padded, and the aspect ratio is always exactly right. It's the better choice when the PDF is for viewing on screen.
A4 or Letter places each image centred on a standard page with a small margin, which is what you want when the PDF is going to be printed and needs to match other printed pages.
Reordering
Drag any item in the list up or down before creating the PDF — pages come out in the order shown, top to bottom. Removing an image only removes it from the list; nothing is deleted from your device.
Common questions
How many images can I combine?
There's no fixed limit — it depends on your device's memory, since everything happens in your browser. A few dozen ordinary photos works comfortably on most phones and computers.
What's the difference between Fit to image and A4/Letter?
Fit to image makes each PDF page exactly the size of its photo, so nothing is cropped or padded. A4 or Letter places each image centred on a standard page size, which is usually what you want if the PDF will be printed.
Are my images uploaded anywhere?
No. The PDF is built entirely in your browser using a JavaScript library, and nothing is sent to a server. That also means very large batches depend on your own device's memory rather than an upload limit.
Can I change the order of the images?
Yes. Drag any image in the list to reorder it before building the PDF. Pages come out in the order shown in the list, top to bottom.
