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.

Does PixReqly upload my image?

No. This tool uses your browser's image canvas functionality. It does not send your image to our server for processing. File size and quality may vary depending on your browser and the source image.

Frequently asked questions

Why does the height change when I enter a width?

Keep original aspect ratio is on. Uncheck it to enter independent dimensions, then select Crop or Fit to avoid stretching.

Can I resize to exactly 300 × 300?

Yes. Enter 300 in both fields, turn off the aspect-ratio lock and select Crop to exact size. Review the crop before downloading.
