Change image dimensions in pixels

Use this image resizer when a website, form, marketplace or content system asks for a specific width and height. The aspect-ratio lock updates the other dimension automatically so people and objects do not look stretched.

How to resize an image

  1. Select a JPG, PNG or WebP image.
  2. Enter the required width or height. Leave aspect ratio enabled for proportional resizing.
  3. Choose an output format and quality, resize, review and download.

Pixels are not file size

Dimensions describe the number of pixels; KB or MB describes storage size. Reducing dimensions usually reduces file size, but format, detail and quality also matter. If a service specifies a maximum number of kilobytes, resize first and then use the image compressor.

Quality and privacy

High-quality browser resampling is used for the output. JPG removes transparency and uses a white background; PNG preserves transparency; WebP can preserve transparency with a smaller file in many cases. Your selected image is not sent to FigureOwl.
