Toolora’s image resizer changes the pixel width and height of an image without requiring desktop editing software. It is useful for website images, social posts, thumbnails, email signatures, product photos and any workflow that needs specific dimensions.

When Keep aspect ratio is enabled, changing one dimension automatically calculates the other so the image does not look stretched. You can also enter both dimensions manually when an exact canvas size is required.

What to know before using this tool

Resizing changes the number of pixels in an image. Making an image smaller can also reduce its file size, while enlarging an image creates more pixels but cannot restore detail that was not present in the original. For best results, start from a source image that is at least as large as the final dimensions you need.

The tool keeps PNG output for PNG input, WebP for WebP input and otherwise uses JPG. This helps preserve familiar file formats while providing a simple one-step resize workflow.

How to use it

  1. Choose an image from your device.
  2. Enter the desired width or height in pixels.
  3. Keep aspect ratio enabled for proportional resizing, or disable it if you need independent dimensions.
  4. Click Resize Image.
  5. Download the resized file and check it at the size where you plan to use it.

Common uses

  • Preparing hero images and thumbnails for websites.
  • Creating images that fit a CMS or marketplace dimension requirement.
  • Reducing very large camera photos before sharing.
  • Matching graphics to presentation, email or profile dimensions.

Tips for better results

  • Avoid enlarging a small image too far because it can look soft or pixelated.
  • Keep aspect ratio enabled unless stretching is intentional.
  • For an exact visual area rather than simple scaling, use the Image Cropper.
  • After resizing, use the Image Compressor if you also need a smaller file size.

Frequently Asked Questions

Can I resize an image without changing its proportions?

Yes. Keep aspect ratio is enabled by default, so changing width or height updates the other dimension proportionally.

Does resizing make an image file smaller?

Reducing pixel dimensions often reduces file size, although the exact change depends on the image format and content.

Can I enlarge an image?

Yes, but enlarging cannot create genuine detail that is missing from the source image, so very large increases may look blurry.

Which output format is used?

The tool keeps PNG for PNG input, WebP for WebP input and uses JPG for other common image types.

Is the image uploaded for resizing?

The resize operation is designed to run in your browser rather than uploading the selected image to this WordPress website for processing.
