To not detain you on this page, you can go straight to this online photo resizer tool to see the result immediately.
If you want to know more, let's take a deep breath and read this article. We promise it won't be boring. Instead, we should comprehend the problem and the reasons behind it. And the most crucial part - is how to resize images for Instagram eventually!
While everyone is obsessed with Instagram, many apps emerge to resize images, and it seems like they do a good job. Such tools also exist because Instagram forces its users to use exact photo sizes when uploading pictures.
If you don't care about the reasons for various image sizes and why many platforms enforce them, please skip the how to fit the whole picture on Instagram section.
And, a simple answer: it's easier for Instagram to manage photos(and videos too). Imagine you should store images from your friends and then show them on an app you've created specifically for presenting pictures.
Your friend A gives you a picture of her cat, and it's 120x340 px. The other friend, B, asks you to store an image of his selfie, 500x800 px. You also took pictures from other friends, and they're different in size.
When you upload the pics to the app, it's now complicated to show them because of various sizes. For example, someone will see a 120x340px pic from a laptop. It's hard to see the cat there without zooming in a lot. The other problem is image consistency. You scroll a feed, and the images there are so different! Some are pixelated because they're small. The others are too big. They just can't fit your screen or are resized incorrectly.
What do you do? Probably, you'll ask your friends to give you pictures of the same size. Therefore, your app's users may scroll the feed to see the same images in dimensions on a laptop, mobile phone, or whatever device.

Instagram, fortunately, accepts almost all images you upload. However, it resizes them by its choice. The primary rule is to crop the area which seems not to fit a target size. Instagram won't save aspect ratio. Instead, it tries to transform an image to allow Instagram to publish it.
You might wonder why Instagram adds the white borders in the area that is cropped? It's how they handle resizing. There's no way to do so correctly on the Instagram app. But you may resize pictures in other apps. Probably, you did. Most of them do the same!

There are multiple options to tackle the issue. For example, configure your camera to take photos in a particular size suitable for Instagram. Brr, it is complicated.
So, let's go the easy way. We've created an online photo resizer tool for this very problem. It resizes any image without cropping and without adding white borders. You may also resize images without cropping for not only Instagram(or Facebook, Twitter, etc.) but for any other platforms. You need to know the exact size the app/platform uses. For example, for an Instagram post the size is 1080x1080px, a square. And, as you know, making square photos isn't easy. You should configure the camera or make transformations for the photos after shooting.

Below you may find the exact sizes that Instagram uses for your convenience.
Instagram preserves your original photo size at a width of 1080 pixels. However, it will stretch the image if its height exceeds 566 pixels. Your photo will be stretched if it is less than 320 pixels in width. It will be reduced if it is more than 1080 pixels in width. If your post is not square, it will be resized as needed.
In this article, you've learned how to resize images for Instagram without cropping online(using our tool). Of course, you may try using other apps that resize pics and cropping. For example, you can do whatever you want in Figma, but it takes more time.
