Before uploading your social media posts or sharing professional presentations, you often need to edit your photos and make some adjustments. For instance, you may want to reduce the image file size for online sharing, convert to a specific format, or resize your picture for a particular platform.
While editing images, managing their dimensions can be a headache. In that case, you need an image size converter to easily resize your photos to fit any need. This article focuses on image size conversion and shares seven tools to resize your JPG, JPEG, PNG, GIF, and BMP images.
Before recommending image size converters, I want to talk about some basic information about image size.
Image size tells the dimensions of an image file, typically measured in pixels (width x height). The more pixels a picture has, the higher its resolution and the sharper it appears. Image resolution is shown in pixels per inch (PPI) or dots per inch (DPI). Higher PPI/DPI turns to more pixels crammed into a smaller area.
An image size converter is a desktop program, mobile app, or online service that lets you modify the dimensions of an image file. This process can contain shrinking or enlarging the image. Some image resizers also offer additional features like cropping, rotating, and converting between different image formats.
An image size converter is mainly used to adjust the dimensions. Sometimes, it lets you change the file size of an image. There are several reasons why you need an image size converter.
Different platforms have varied image size requirements for optimal viewing and performance. An image size converter helps you edit your photos and ensure they appear clear without unnecessary cropping.
Large pictures will slow down website loading times. You can use a photo size converter to optimize the image size for web use and get fast page loading.
Large image files can mess up your email inboxes. An image resizer tool allows you to shrink photos to a smaller size while maintaining a high quality.
For printed photos, the image resolution needs to be high enough to avoid pixelation. An image sizer converter can help you improve the image resolution for high-quality prints.
There are two main approaches to image resizing: resampling and cropping.
Resampling modifies the actual number of pixels in the image file. When you shrink an image file, resampling removes pixels. Conversely, when you enlarge your photo, new pixels will be created. Interpolation algorithms determine how these new pixels are created. The cropping solution involves removing unwanted portions of the image. It effectively changes the image dimensions without changing pixels.
With all types of image size converters available, both online and desktop software, selecting the right tool can be daunting. Here are some factors to consider when you choose your image resizer software.
Features: Some image size converters offer basic editing options like resizing and compressing options. Advanced tools provide more features like cropping, rotating, and batch resizing.
Ease of Use: Look for a photo size converter that allows you to upload your image, select the desired output, and download the resized image effortlessly.
Supported Formats: Ensure the pixel size converter supports the image format you are working with, such as JPG, PNG, GIF, WebP, BMP, HEIC, and more.
Quality Control: Some converters offer more control over the compression process, allowing you to customize quality or file size depending on your needs. Also, you should select an image resizer that won’t add a watermark to your resized picture.
Security: If you are dealing with sensitive pictures, consider using an image size converter that offers secure upload and processing.
Free vs. Paid: Many online converters are free, while more advanced programs might require a paid subscription.
Both Windows and macOS offer basic image editing tools with resizing functions. While not as feature-rich as dedicated image size converter software, they can be sufficient for simple tasks.
Several free and open-source image converters offer features like batch resizing and format conversion. For more advanced users, professional photo editing software like Adobe Photoshop provides powerful image manipulation tools, including photo resizing and format conversion.
This part explores the different types of image size converters available for Windows PC, Mac, iOS, Android, and even online solutions.
