How to resize an image

  1. Upload your image (JPG, PNG, WebP, or HEIC).
  2. Pick a mode: exact dimensions, percentage scale, or target file size in KB.
  3. Download the result and compare it with your original before sharing.

A practical starting point

For a 600-pixel-wide upload, enter the width and preserve aspect ratio unless both dimensions are mandatory. Check the downloaded dimensions.

Frequently asked questions

What are the limits of Resize Image?

Pixel dimensions and byte size are separate requirements. A target KB size is not guaranteed for every image. Enlarging cannot restore missing detail.

How should I check the Resize Image result?

Check dimensions, format and bytes together. Review a portal's minimum resolution and aspect ratio before reducing quality further.
