Frequently asked questions
Does resizing reduce quality?
Making an image smaller keeps it sharp. Making it much larger than the original adds pixels that weren't there, so it can look soft.
How do I keep the proportions?
Keep "Lock aspect ratio" on. When you change the width, the height updates automatically, and vice versa.
Are my images uploaded?
No. Resizing happens in your browser using your device.
