Free Image Resizer

Change image dimensions instantly with high-quality browser processing.

The image resizer changes the width and height of a JPG, PNG or WebP image in your browser — nothing is uploaded, so it is safe for personal photos and confidential screenshots. Keep the aspect ratio locked to avoid distortion, or unlock it to stretch to an exact size. Use it to shrink photos for email, web or social media without opening a desktop editor.

Your image is processed locally in your browser and is not uploaded.

How to resize an image

  1. Click Add image or drag a JPG, PNG or WebP into the tool.
  2. Enter the target width and height in pixels. Keep Lock aspect ratio on to avoid distortion.
  3. Click Download to save the resized image.

Worked example

A 4000 × 3000 phone photo needs to fit a website hero image that is 1200 px wide. You lock the aspect ratio, set the width to 1200, and the height auto-adjusts to 900. You download a 1200 × 900 image that is roughly 15× smaller in file size — perfect for fast page loads, and the original 12 MP photo never left your device.

Frequently Asked Questions

Are my photos private?

Yes, our image resizer runs entirely on your device. We do not upload or store any of your photos.

How do I keep my image from distorting?

Keep the 'Lock Aspect Ratio' toggle enabled. When you change the width, the height will adjust automatically to maintain proportions.

What happens to the quality when I enlarge an image?

Enlarging an image past its original dimensions may result in a blurry or pixelated output due to standard browser interpolation.
