Frequently asked questions
Are my images uploaded?
No. Resizing happens in your browser on your device.
Can I make an image bigger?
Yes, but enlarging cannot add detail, so the image may look soft.
How do I resize an image without stretching it?
Keep ‘lock aspect ratio’ on so height changes automatically with width.
What size should blog images be?
Around 1200–1600 px wide works well for most blogs and themes.
