How to resize photos

It can often happen that the size of photos is too large to share via e-mail or to upload to websites. In these cases, it may be useful to reduce or compress the photos without sacrificing quality. In this article, we will discuss how to resize and enlarge photos on Windows, MAC OSX and Linux PCs.

Resize photos on Windows PCs

Windows has a built-in photo editor called Paint, which allows you to edit and resize images.

1. Open the photo you want to resize with Paint by right-clicking on the photo and choosing “Open With” and then “Paint.”
2. Click on the “Image” tab and select “Resize”.
3. Select “Pixels” and set the width or height of the image.
4. Make sure the “Lock aspect ratio” option is enabled to ensure that the ratio of the image is maintained.
5. Click “OK” to save the changes and resize the image.

To resize multiple images at once, you can use the Batch Editor in Paint or an external tool such as Bulk Resize Photos.

Resize photos on MAC OSX PCs

On MAC OSX, you can use the built-in Preview app to edit and resize images.

1. Open the photo you want to resize with Preview by double-clicking on it.
2. Click on “Tools” in the menu bar and select “Resize”.
3. Select “Pixels” and set the width or height of the image.
4. Make sure the “Lock proportions” option is enabled to ensure that the image’s proportions are maintained.
5. Click “File” and then “Save” to resize and save the image.

To resize multiple images at once, you can use the Bulk Resize Photos app or the Automator tool.

Resizing photos on Linux PCs

On Linux, you can use the GIMP (GNU Image Manipulation Program) or the ImageMagick tool to edit and resize images.

GIMP

1. Open the photo you want to resize with GIMP.
2. Click on “Image” in the menu bar and select “Scale image”.
3. Set the width or height of the image and make sure the “Link aspect ratio” option is enabled.
4. Click “Scale” to save the changes and resize the image.

ImageMagick

1. Open the terminal and navigate to the folder where the image is located. 2. Type the following command: convert [inputfile]-resize [width]x[height] [outputfile], where [inputfile] is the name of the image you want to resize, [width] and [height] are the new dimensions of the image, and [outputfile] is the name of the new image.

2. Press Enter to execute the command and resize the image.

To resize multiple images at once, you can use Batch mode in GIMP or ImageMagick’s options. There are also several other tools and apps available that can help you resize multiple images at once, such as XnConvert and Converseen.

Common mistakes

A common mistake when resizing images is keeping the original ratio, which can distort the image. Therefore, always make sure that the “Lock aspect ratio” or “Lock proportions” option is enabled when resizing an image.

Another common mistake is resizing images to too small a size, making the image unclear. It is therefore important to check that the image is still clear and sharp after resizing.

Image resizing often comes in handy

Image resizing can be done in different ways and on different operating systems. It is important to maintain the image’s proportion and ensure that the image is still clear and sharp after resizing. By using the right tools and settings, you can easily resize and save multiple images at once in a snap.
