How to use Image Resizer

  2. Type a width and height in pixels, choose a percentage, or tap a preset.
  3. Press Resize images and download the results.

When do you need to resize an image?

Every website and app asks for different picture sizes. A YouTube thumbnail should be 1280×720, an Instagram post is 1080×1080 and a story is 1080×1920. Resizing to the exact size stops platforms from cropping or blurring your picture.

  • Prepare social media posts, banners and profile pictures.
  • Shrink large phone photos before uploading to a website.
  • Make a set of photos the same size for a catalogue or presentation.

Keep the ratio or stretch?

With Keep ratio on, the picture is scaled without distortion, so faces and logos never look squashed. Turn on Stretch to fit only when a form demands an exact width and height.

Will resizing make my photo blurry?

Making a photo smaller keeps it sharp. Making it larger cannot add detail that is not in the original, so big enlargements look soft. Start from the largest original you have.
