How to use Image Resizer

Resize your images online to custom dimensions (width and height) with aspect lock options.

Processed on this deviceNo Beginware file upload
  1. 01

  2. 02

    Set the dimensions

    Enter the required width and height. Keep the aspect-ratio lock enabled when you want to avoid stretching the image.

  3. 03

    Review and download

    Check the preview and output dimensions before downloading the resized copy. Keep the original until you have verified the result.

Input
A 2400 × 1600 JPG product photo
Result
Set the width to 1200 px with aspect lock enabled; the proportional height is 800 px.
Before you rely on the result

Limits and checks

  • Resizing changes pixel dimensions; it does not restore detail that is missing from a small original.
  • Very large images require substantial browser memory and may be slower on mobile devices.
  • Always check transparency and output quality before replacing the original file.
Specific guidance

Image Resizer questions

Will resizing stretch my image?

Not when the aspect-ratio lock is enabled. If width and height are changed independently, the image can be distorted.

Does the image leave my device?

No. Beginware reads and processes the supported image in the active browser session.

Can I enlarge an image?

Yes, but enlarging creates additional pixels rather than new detail, so the result may look softer.
