The images we take with our digital cameras are pretty, but often far too large to easily send through email or upload to a website. If you need to resize your image, there are a variety of tools available for you to do so, and most of them are free. In this article, we'll explain how to resize an image to your liking using free web applications, MS Paint, Google Picasa, GIMP, and Adobe Photoshop. Scroll down to get started!
Steps
-
Open the web application of your choice. There are many web services that will resize your images for free. You will need to upload your image to the site and then choose your resize options. Most programs offer the same basic features, though some will have extras available that others don’t. Several of the more popular sites include:
-
Upload the image you want to resize. You will have to navigate to the image on your computer, and then upload it to the website. Once the upload is complete, the image editing options will appear.
- Most web applications have a maximum file size that is allowed to be uploaded, typically around 5 MB.

Use the app features to resize the image to your liking. Depending on which service you are using, you may have multiple options when it comes to resizing. You may be able to choose a percentage of the original size, or several preset size. Almost all services will allow you to set an exact size in pixels that you would like to resize to.
-
Set the quality of the image by adjusting the compression. Most resize services will let you set how much compression the image will have, which will affect the quality. The higher the compression, the lower the quality and the smaller the file size.
-
Add any other effects you'd like. Depending on the service you are using, you may have access to other options such as rotation, color changes, filters, and more. Choose the effects that you want.
-
Download your updated and resized image file. Once you’ve picked all of your settings and effects, click the Download button. This may be called a Resize button or something similar. The newly-edited photo will be downloaded to your computer, which you can then transfer to wherever you need.

Download an Instagram resizer app. Since Instagram uploads take place entirely on your mobile device, it is much more convenient to edit the photos that you take directly on your phone. There are multiple apps available that can resize your photos so that Instagram does not crop them.
- If you want to resize a photo on your computer before uploading it to Instagram, resize it to 612 X 612 pixels. This is the size of the Instagram format.
- If you want to post big pictures on Instagram that are too large to post normally, this resizing app will help you do that.
-
Run the resizer app. Depending on the app, the features may change. Most will allow you to resize your image so that it fits, and others will allow you to crop your existing image so that the cropped section fits into Instagram.
-
Upload the image to Instagram. Open your Instagram app and browse for your newly resized image. Upload as you normally would and you won’t lose any part of the image due to cropping.

Tips
- To make the image files as small as possible, they need to be saved in the right file format. The three most common formats are JPG, GIF, and PNG. [11] X Research source
- JPG files, which are the default file format used by most digital cameras, are ideal for full-color images. This format has the best ratio between size and image quality.
- GIF files are smaller, but only contain 256 colors, which can lead to discolorations. This format is outdated and it is highly recommended to not use it anymore.
- PNG files support true color (+ transparency) and are saved without any loss of information. Depending on the image content they can get larger than either of the other two formats.
Thanks
For most resized pictures, including pictures for wikiHow, the best format will be JPG.
