What does image resizing mean?
Resizing changes an image’s width and height. It can help when a website, form, or application requires specific dimensions.
For better results
- Start with a good-quality original.
- Keep the aspect ratio when possible.
- Avoid enlarging a small image too much.
- Check the final dimensions before downloading.
If you need a smaller file as well as smaller dimensions, use the image compressor after resizing.
What is the easiest way to resize an image?
The easiest way to resize an image is to use an online image resizer. Choose your image, enter the required width and height, and save the resized image.
For example, if your photo is 2000 × 1500 pixels and you need a smaller image, you can resize it to 1000 × 750 pixels while keeping the same aspect ratio.
How to change the size or dimensions of an image
Changing an image size means changing its width and height in pixels. The steps are simple:
- Choose the image you want to resize.
- Enter the required width in pixels.
- Enter the height if you need an exact size.
- Keep the original aspect ratio when possible.
- Resize and download the image.
This works for common image formats such as JPG and PNG.
How to resize a photo without stretching it
To resize a photo without stretching or squashing it, keep the same aspect ratio. If you change the width, the height should change proportionally.
For example, a 1600 × 1000 image can be resized to 800 × 500. Both dimensions are reduced by the same proportion, so the photo keeps its original shape.
How to resize a JPG or PNG image
You can resize both JPG and PNG images by changing their pixel dimensions. JPG is commonly useful for photographs, while PNG is often useful for graphics, logos and images that need transparency.
Choose the format that fits your image and the requirements of the website, app or form where you plan to use it.
