Frequently asked questions
How do I resize an image to a specific size in pixels?
Add the image, type the width and height you need and click Resize. Turn off Keep aspect ratio if you need the exact width and height even though the shape changes.
How do I resize an image without stretching it?
Leave Keep aspect ratio switched on and enter only the width or the height. The other side is calculated from the original proportions.
Can I resize by percentage?
Yes. Choose By percent and enter a value such as 50 to make the image half as wide and half as tall. This is a quick way to shrink large camera photos.
Does resizing reduce image quality?
Making an image smaller keeps it sharp at the new size. Making it larger cannot add detail, so enlarged pictures look softer. JPG and WebP are saved at high quality.
What is the largest size I can create?
Up to 8000 pixels on a side and 16 million pixels in total. Bigger canvases are not reliable in mobile browsers.
Is it safe to resize my photos here?
Yes, nothing is uploaded. The resizing happens inside your browser, so we never see your pictures.
