Questions and answers
Will resizing stretch my image? +
Not while "Keep aspect ratio" is on. Each image is scaled to fit inside the width and height you set. Turn the option off only if you need an exact size and accept distortion.
Can I make an image bigger? +
Yes, by entering a larger size or a percentage above 100%. The browser smooths the result, but enlarging cannot add detail that was not in the original.
What size should I use for social media or a website? +
For most web pages 1200–2000 pixels wide is plenty. Check the current recommendations of the platform you post to, since they change from time to time.
Can I resize several images to the same width? +
Yes. Add all of them, enter a width and leave height filled in proportionally. Every image keeps its own proportions while fitting the size you chose.
