FAQ
What does "longest edge" do?
The longer side of each picture is made no longer than your number, and the other side follows. Pictures that are already small enough are left as they are, so nothing is enlarged.
What does "keep proportions" do?
Each picture keeps its own shape. Type the width and the height follows, or type the height and the width follows. Turn it off to stretch every picture to exactly the size you type.
Is the picture stretched?
Only when you switch off "keep proportions".
Can I make a picture bigger?
Yes, with an exact size or a percent above 100. The picture gets more pixels but no more detail, so it can look soft.
Is metadata removed?
Yes. Camera details and location are left out, and photos stay upright.
