Resize Images Online: Change Dimensions and Reduce File Size

Resize and crop JPG, PNG, or WebP images in your browser. Set the dimensions for a document, website, or application, review the image, and export a separate copy.

  1. 1

    Add an image

    Choose a supported image and open the image editing workspace.

  2. 2

    Set dimensions and crop

    Choose width and height, keep the aspect ratio when appropriate, and adjust the crop.

  3. 3

    Check detail and size

    Inspect small text and faces at the intended size. Adjust output quality where available.

  4. 4

    Download the resized image

    Export the image, then check its pixel dimensions and actual file size before uploading it elsewhere.

Practical uses

Prepare application photos, website graphics, email attachments, and document illustrations. A pixel-size requirement and a limit such as 50 KB are different constraints: check both on the exported file.

Tips for a better result

  • Keep the aspect ratio to avoid stretched faces or logos.
  • Enlarging a small image cannot restore missing detail.
  • A specific KB target depends on content, dimensions, format, and quality.

Frequently asked questions

How do I resize an image to 50 KB?

Reduce image dimensions and adjust output quality where available, then check the downloaded file size. A precise 50 KB result is not guaranteed; keep text and faces readable while working toward the upload limit.

What is the difference between resizing and compressing an image?

Resizing changes pixel dimensions. Compression changes how image data is encoded. Smaller dimensions and lower JPEG quality can both reduce bytes, but may remove detail.

Are images uploaded for resizing?

Supported resizing and cropping run in your browser. The website still downloads normal resources; local processing does not mean the page makes no network requests.
