How to Resize an Image Without Losing Quality

By Prestofiles Team · · 2 min read

Resizing does not have to make a photo blurry. Learn the few simple rules that keep a picture sharp when you change its size.

A blurry photo after resizing is almost always caused by one of two things: the picture was made bigger, or it was saved again and again at low quality. Both are easy to avoid.

Make it smaller, not bigger

When you shrink a photo, the tool throws away pixels you do not need and the picture stays sharp. When you enlarge a photo, the tool has to invent new pixels, and the result looks soft. So always start from the biggest original you have and resize down.

Steps to resize a photo

  1. Open the Resize Image tool.
  2. Choose your JPG, PNG or WebP file. You can select many files at once.
  3. Type the new width and height in pixels, or use a percentage such as 50%.
  4. Download the result.

Your pictures are handled in your browser, so they are not sent to a server.

Keep the shape the same

If you change only the width and leave the old height, the picture looks stretched. Change both numbers by the same ratio. For example, a 4000 x 3000 photo at 50% becomes 2000 x 1500. Using a percentage is the easiest way to avoid mistakes.

Good sizes to remember

  • Websites and blogs: 1200 to 1600 pixels wide is plenty for most pictures.
  • Email and chat: 1000 to 1280 pixels wide keeps files light.
  • Social media: use the exact size for the platform. See our social media image size cheat sheet.

Need a smaller file as well?

Pixels and file size are two different things. After you resize, you can reduce the size in KB with the image size reducer, or read how to compress an image without losing quality.
