Frequently asked questions
Will resizing an image reduce its quality?
Making an image smaller keeps it sharp, because pixels are removed cleanly. Enlarging beyond the original size can look soft, since the browser has to invent new pixels.
What does locking the aspect ratio do?
It keeps the original width-to-height proportion. When you change the width, the height is recalculated automatically so the picture is never stretched or squashed.
Is there a size limit for images?
There is no upload limit because nothing is uploaded. Very large photos (for example 100+ megapixels) depend only on your device memory.
