Note: Very large images may exceed your phone's memory. For an exact-KB goal, use JPG or WebP; PNG compression is lossless and may not reach the target. Converting to JPG replaces transparent areas with white.

How to resize an image in pixels

  1. Upload a JPG, PNG, or WebP image.
  2. Set your preferred dimensions and output format.
  3. Click Process Image and review the output size.
  4. Download the image directly to your device.

How to crop to 300 × 300 without stretching

Uncheck Keep original aspect ratio, enter 300 as both width and height, and select Crop to exact size. The center of your photo is kept. For a full image with padding, choose Fit whole image instead.
