10 Best Instagram Photo Resizer Apps & Online Tools

Instagram photo resizer tools come in handy when you need to have the correct propositions of the image or video without having to crop it. We discuss the multiple Instagram post sizes in the later section of the article; However, if you don’t want to resize the image, one of the options you can do is publish a continuous carousel post that fits the best for landscape-type Instagram posts. If you are ready to resize the Instagram images without or with a little loss of quality, here are our top picks.

1. Square Fit

Instagram Post Resizer


Price: Freemium

  • Fit, crop, rotate, flip, and resize the image without loss in quality.
  • Resize as per the social media platform.
  • Photo editor and resizer in a single app.
  • 150 photo backgrounds and patterns.
  • Try without paying any money.
  • Share directly to social media without leaving the app.

Square Fit is one of the best apps for resizing Instagram photos; it is loaded with a bunch of features and makes it easier for your to resize your images without having to crop them. Most of the Instagram photo resizer tools and apps that we have used either blur the background or keep it in a solid color, such as black or white. This is sometimes okay, but if you wish to make it look more creative and fill it with different backgrounds, this is the right app for you.

Using Square Fit Instagram photo resizer, you can not only resize the images but also edit them. Yes, it is a two-in-one powerful tool for those who wish to edit and resize the images rather than making several copies each time. One of the captivating features is there are more social media options, such as Facebook, Twitter, and YouTube, which allow users to resize the images as per their requirements. Once done, you can directly share the image on the platform using the image resizer app.

What we loved the most is despite being a freemium app, you don’t have to suffer the “enter your credit card details” page. This app can be used for free without paying a penny. However, the free version restricts the users with available features and editing options.

Sadly, this Instagram photo resizer tool is only available on the App store; Meaning only iPhone and iPad users can use it.

2. No Crop & Square for Instagram

Price: Freemium

  • Post full-size photos on Instagram without cropping images.
  • Rotate, flip, and resize photos.
  • Add images to the background of the post.
  • Photo editor with 30+ filters and 400+ stickers and emojis.
  • Make your own collage.
  • Add text with multiple font options.

“No Crop and Square for Instagram” is another all-in-one Instagram photo resizer app for Android and the best alternative to Square Fit. There are a lot of similar features in comparison to the Square Fit app, and the best part is the availability for Android devices. Since Square Fit is not available for Android, this is the perfect replacement or alternative to the Instagram photo resizer.

There are a bunch of powerful features, such as resizing full-size images without having to crop the edges, rotating and flipping as per your need, and adding images to the background of the post. Adding the background image is the best feature that we love; the traditional and old Instagram image resizer apps add blurry sections or solid colors, which are quite common.

Additionally, this Instagram photo resizer app is also a powerful photo editor that allows you to add 30+ filters and 400+ stickers and emojis to your Instagram post. This also adds to writing on your photo using a text editor tool with numerous fonts or also making a collage of all your images.

The “No Crop and Square for Instagram” app is a freemium tool and allows you to use the free features without having to pay. However, if you are a regular user and love using it, the subscription price is quite low, and it is one of the affordable tools.

Instasize has been a long-time user favorite when it comes to resizing Instagram photos or editing them. There are a couple of loved features, such as adding photo backgrounds, filters, and stickers; However, these are only available in the affordable premium subscription. The free version is a powerful image editor and can resize, flip, or rotate your image as per your need.

One of the creative features on Instasize that we loved using is the creative border options. Here, you will find a bunch of creative borders which outshine the image and make it look more attractive and appealing. This feature is missing in most Instagram photo resizer apps or online tools.

In addition, the app also has similar features to other resizer tools and apps, such as adding text to the photo or making a collage. Additionally, the app is available for both Android and iOS platforms, which makes it more desirable to use.

4. INSTFIT – Post Without Cropping

Image resizer for Instagram on App store iPhone


Price: Freemium

  • Photo fitting and resizing.
  • 140+ background styles.
  • 100+ filters and overlays.
  • Make collages and add text.
  • Export resized Instagram photos in high quality.
  • Advanced HSL editing feature.
  • Loaded with resources on affordable premium subscription.

If you are among those who love to give their images a detailed edit before resizing them and publishing them on different platforms, INSTFIT is the perfect app for you. Though it is an Instagram photo resizer, it is also a powerful photo editing app. Similar to the other apps on the list, INSTFIT also provides over 140+ background images and 100+ filters and overlays. However, there is something more that excites us than the background image and filters; it is the HSL editing for much more freedom on how you want your image to look.

The HSL editing levels allow you to edit the Hue, Saturation, and Luminance for much more detailed and toned images. Usually, to edit in such a way, users first use image editing apps such as photoshop or lightroom and then use the Instagram photo resizer app. But thanks to INSTFIT that you can do both together on a single app and publish it right away without losing any quality or parts of the image.

The app is only available on the App Store and is a freemium app with the most affordable pricing. You can use the free version, but that would limit the resources and features restricting you from making the most visually appealing edits.

One of the advantages of this Instagram photo resizer tool is batch resizing of images which we love the most. There are several tools on the list, but not many of them provide batch resizing of images which is tiresome as you will have to resize images individually with Ads between them.

Another benefit of using this Instagram post resizing tool is the custom aspect ratios and resolutions that allow you to resize the images as per your need. Instagram has several aspect ratios, and if you don’t want your image to be cropped, these aspect ratios are to be followed. But what are these aspect ratios? We have discussed them further in the post.

We have been using the Photo and Picture resizer tool not only for Instagram but for platforms like Facebook and YouTube, as there are certain aspect ratios for banner headers and other images. In such cases, no one would want a poor-quality image after the resizing is done; this is where the improved quality and compression of this tool come into the picture.

Guide on Instagram Post Sizes | Post, Story, IGTV, and Reels

Before using any of the Instagram photo resizer apps or online tools, the firstmost task is to know the available post sizes that can be used. There are three size options for uploading photos on Instagram, the post size for reels is different, and the Instagram story size slightly differs from the reels. So, there are a bunch of size options, and you need to choose the size as per your post preference or requirement.

Here are the available Instagram post size options based on what type of post you want to upload.

Instagram Image/Picture Post Size

There are three types of image aspect ratios that can be used to post on Instagram; Vertical, Landscape, and Square. All these image aspect ratios are different from each other, and you need to choose the correct aspect ratio based on your image to avoid cropping.
