Frequently Asked Questions
Can I resize multiple images to the same dimensions?
Yes! Drop as many images as you like and set one dimension — all images will be resized to those exact dimensions in one click.
What does aspect ratio lock do?
When locked, changing the width automatically adjusts the height proportionally so your image does not appear stretched or squished.
How do I resize an image for Instagram?
Use the Instagram preset (1080×1080) for square posts, or enter 1080×1350 for portrait. Select JPEG at 85% quality for best results.
Will resizing to a larger size improve quality?
No — upscaling a small image to a larger size cannot add new detail. The image will be larger but not sharper.
