Resize images

Resize several images at once to the dimensions your website needs. Everything happens in your browser; files stay on your computer.

A large photo card and a smaller copy are matched to their dimensions with a ruler.

How it works

Bringing pictures to the appropriate size

  1. Selecting pictures
  2. Adjust target dimensions and format
  3. Download Scaled Images

Drag images here or click

Up to 20 files. Everything stays on your computer; nothing is uploaded.

Target size

Format

Below 70%, edges and surfaces can look visibly rough. 85% usually offers a good balance between file size and appearance.

Which size should you choose?

Measure the displayed width and double it for high-resolution screens. These use two device pixels per CSS pixel, so an image with too few pixels can look blurry.

A 4,000-pixel-wide photo displayed at 600 pixels transfers roughly forty times the necessary data. On many websites, images outweigh scripts, stylesheets and fonts combined.

What's happening here

No distortion. With aspect ratio locked, width and height are maximum limits. The image fits within them and may be smaller in one direction. Without the lock, it is stretched to the exact dimensions.

JPEG export adds a white background. JPEG does not support transparency. Without a background, transparent areas would turn black. Use PNG or WebP to retain transparency.

You can enlarge images using the percentage setting, but resizing cannot restore detail missing from the original.

If your main goal is a smaller file, the WebP converter is the more direct option. To find oversized images on your website, use the Website check .
