Resizing photos is a common task for many computer users, whether you’re looking to share images on social media, send them via email, or simply free up space on your hard drive. However, with so many different methods and software options available, it can be difficult to know where to start. In this article, we’ll take a closer look at the different ways you can resize a photo on your computer, including the built-in tools that come with your operating system, as well as some popular third-party software options.
Understanding Image Resolution and File Size
Before we dive into the different methods for resizing photos, it’s essential to understand the basics of image resolution and file size. Image resolution refers to the number of pixels that make up an image, with higher resolutions resulting in more detailed and clearer pictures. File size, on the other hand, refers to the amount of space an image takes up on your hard drive, with larger files requiring more storage space.
When you resize a photo, you’re essentially changing the number of pixels that make up the image, which can affect both the resolution and file size. Downsizing an image, or reducing its resolution, can help to decrease the file size, making it easier to share or store. However, upsizing an image, or increasing its resolution, can result in a larger file size and may not always produce the desired results, as the image may become pixelated or distorted.
Using Built-in Operating System Tools
Both Windows and macOS come with built-in tools that allow you to resize photos without the need for additional software. On Windows, you can use the Photos app, which is included with the operating system. To resize a photo using the Photos app, simply open the image, click on the Edit button, and then select the Resize option from the menu. From here, you can choose from a range of preset sizes or enter a custom size.
On macOS, you can use the Preview app, which is also included with the operating system. To resize a photo using Preview, open the image, click on the Tools menu, and then select the Adjust Size option. From here, you can enter a custom size or choose from a range of preset sizes.
Limitations of Built-in Tools
While the built-in tools that come with your operating system can be convenient, they may not offer the level of control or flexibility that you need. For example, the Photos app on Windows and the Preview app on macOS may not allow you to resize images in batches, or they may not provide the same level of precision when it comes to entering custom sizes. Additionally, these tools may not support all image file formats, which can limit their usefulness.
