Image Resizer: Change Photo Size by Pixels or Percent

Social networks, marketplaces and CMS themes all ask for different image sizes. Enter a width, a height or a percentage, keep the proportions locked and download the resized file. Large images are scaled down in steps for a cleaner result.

How to use it

  1. Choose an image. Its current size is shown.
  2. Pick pixels or percent, type a width or height and choose the output format.
  3. Press Resize, check the preview and download.

Example

A 4000 × 3000 phone photo resized to 1600 px wide with the ratio locked becomes 1600 × 1200 and is usually under 400 KB as JPEG.

Benefits

  • Aspect ratio lock prevents stretched photos.
  • Quality slider for JPEG and WebP lets you trade sharpness for size.
  • Nothing is uploaded.

Limitations

  • Enlarging a small image makes it blurry; no tool can add detail that is not there.
  • Output is limited to 16,000 px per side to protect your browser memory.

Frequently asked questions

Does resizing reduce file size?

Usually yes, because fewer pixels need fewer bytes. For a specific KB limit use the compressor to target KB tool.

Will EXIF data be kept?

No. Re-encoding through the browser removes metadata such as GPS.
