Resize image for Instagram without cropping


Have you ever tried to upload a photo to Instagram only to find it's the wrong size?

It's easily done, especially given the many different kinds of Instagram post, each with different resolution and aspect ratio requirements.

One solution is to crop your picture to the required size. But this is a flawed way of dealing with the probem, as if the ratio is at all different then you'll be losing some of the picture.

The free tool above enables you to resize your photos without cropping the edges off them, meaning you can display the whole thing with no bits missing.

Whether you're looking to post Instagram stories, profile pictures, or whatever, if they're still images you can prepare them here.

Let's explore how.

Why avoiding cropping can be crucial for landscape and portrait photos alike

Resizing a landscape photos to fit in, for example, a square, involves cropping the sides off. Thus stripping the photo of all the natural majesty and sense of space. Resizing without cropping is therefore preferable, as it preserves the natural scenery, including horizons, mountains, and oceans

Resizing a vertical image aka a portrait photo comes with a similar set of issues. Vertical photos often have aspects at the top and bottom you don't want to lose. Using this tool, you can keep the person's important physical features intact – the whole photo will be displayed.

With the above tool, you can easily resize photos for Instagram without losing any of the essential details that makes a landscape special, allowing you to preserve the whole picture on Instagram as intended, rather than compromising on it to fit the demands of the platform.

What the tool does

The tool on this page resizes your files to the resolution specified in the drop-down box.

Since in many cases the aspect ratio (shape, in simplistic terms) is different, and no cropping is going to occur, something has to give. In this case, the background will show through as horizontal or vertical strips on either side of the photo.

You the user can decide what that background is. It can either be:

  • White
  • Black
  • A blurred copy of the original photo

The downloadable outcome will be an image with black, white, or blurred bars to the sides or top and bottom, thus expanding the original image to fit the required shape.

What image sizes are supported by Instagram in 2023?

Instagram supports a host of different content types. Each one has its own specific resolution and aspect ratio rules, as follows:

  • 161 x 161 - Photo Thumbnails Size
  • 320 x 320 - Profile Picture Size
  • 420 x 654 - IGTV Cover Photo Size
  • 1080 x 566 - Landscape Photo Size
  • 1080 x 1080 - Square Photo Size
  • 1080 x 1350 - Post Size
  • 1080 x 1920 - Story Size
  • 1080 x 1920 - Instagram And Live Reels Size

Our Instagram resizing tool has all these sizes programmed in - just select the one you want from the drop-down box and the output will fit those image dimensions perfectly.

So whether it's an Instagram profile picture, a reel, or a regular post, you don't have to worry about the specifics, our image resizer will handle that for you.

How to use our Instagram resizing tool to resize images without cropping

We design our tools to be as easy and fuss-free as possible so you can just get on with creating your Instagram posts. We don't require any sign-up, nor any payment – the service is free.

The tool itself is pretty self-explanatory – you don't need to go on a 3-day course to instantly resize images here – but allow us walk you through it anyway:

  1. Use the 'Select Images' button to upload your files (or drag and drop them into the specified area). You can process up to 5 at a time
  2. Select the resolution required from the drop-down box, e.g. 320x320
  3. Click the 'Resize image' button. Our tool will automatically resize the image to the dimensions specified
  4. Now you'll see a pop-up offering a choice of how to extend the image. Choose from a black background, a white background, and a blurred background
  5. All done! You can now download your expanded and resized image or images in the form of a zip file

How to resize multiple images with our resizing tool

Resizing images one at a time can be a pain, especially when you have a big pile to get through. Thankfully, our resizer tool also lets you work in bulk.

Note however, that all your files will be output in the same dimensions, so if you have a lot of photos you should group them together based on how you want the output to look. Do all your square Instagram posts at the same time, for instance.

The process is the same as above.

  1. Click on the 'Select Images' button (or use the drag and drop functionality) to choose up to 5 images for processing
  2. Set the desired resolution in the drop-down (e.g. 1080 x 1080 for a square photo). Note that all your pictures will come out at this resolution. If you need any to be different then process them separately.
  3. Click 'Resize image'
  4. Choose your preferred background: black, white, or blurred
  5. Click the download link to get your resized images in a zip file. The image size (in terms of dimensions) will be as specified in the drop-down

Doing it in bulk is a great way to resize Instagram photos while saving time, but only as long as you're happy with them all being in the same dimensions.

Is my privacy protected while using the resizing tool?

In short – yes.

In long – also yes, but with more details.

Your privacy is very important to us. While it's true that everybody says that, we walk the walk and stand behind our claims. Here's how we go about it:

  • Your images are uploaded via secure SSL connection. This greatly reduces the chances of them being intercepted by third parties.
  • They are processed automatically, without human intervention. Your photos are none of our business. We set up our algorithms to run, and then leave them to it.
  • Your processed images are deleted after 24 hours. You have a full day to download them, after which they're permanently erased from our servers.
  • We don't share your files with third parties. They're your own private files and they stay that way.

You should be rightly suspicious of any service that is free where the revenue generation model isn't obvious.

This service is paid for by the ads that appear on the page, so you don't need to worry about using this particular free image resizer – we're the ethical ones.

General questions about resizing

How to resize an image for Instagram

Resizing an image for Instagram involves changing its dimensions to meet the particular specifications for that purpose (e.g. Instagram posts, profile pictures and so on).

A common way is to manually resize your assets, like so:

  1. Open the image in any decent image editing software, either on desktop or your mobile device
  2. Choose the 'resize' option
  3. Enter the new dimensions based on Instagram's requirements
  4. Apply the changes
  5. Done! Your Instagram photo will now be the size specified

The tool above will easily resize images for you, and also adds bars to the side (or top and bottom) if the aspect ratio doesn't match what's required.

How to make a rectangular picture square for Instagram

To create square pictures from rectangular ones (for sharing on Instagram, for example) you have several options. You can:

  • Crop the image using a cropping tool
  • Adjust its aspect ratio to 1:1
  • Add bars to the side (or top and bottom)

The tool on this page uses the third option and hence allows you to post a picture on Instagram without cropping. It does this by adding bars to extend the image into a square shape, meaning you don't lose any part of the image.

How to crop an image into a square

To crop an image into a square, for example so you can post square images to social media, you need to use editing software to select the part you of the image you want to keep, then remove the rest. In general terms, this means doing the following:

  1. Open the original photo in your chosen editing software
  2. Select the crop tool (this usually looks like a pair of opposing right angles intersecting each other)
  3. Select the area you wish to keep, and apply the changes
  4. You're done – the image will be cut into a square shape, and you can post your picture on Instagram without losing any important elements

If however you want to post square images to Instagram without cropping them the tool on this page will make your images square without you needing to remove important parts.

How to change the aspect ratio of a picture to 1:1

If the aspect ratio of a picture is 1:1 it means the image is square. To change an image to 1:1 ratio, do the following:

  1. Open the image in your favoured editing software
  2. Find the aspect ratio settingsSet 1:1 as the new ratio
  3. Position and resize the image within the 1:1 frame that appears (this will either crop your image or give it sidebars, or some mixture of the two)
  4. Apply the changes
  5. Done – your image will now be square

The tool on this page can effortlessly change the ratio to 1:1 by adding sidebars of your choice, so you can post the whole picture on Instagram.

How to extend an image to make it square

Extending an image is one of the key ways of resizing an image to fit new dimensions. The typical way of doing this is to add a background, which sits behind your image, and becomes visible in which ever dimension doesn't reach to the edges of the frame.

  1. Open the image in your choice of image editing software
  2. Change the aspect ratio to 1:1
  3. Add a background (or a new layer that you move behind your main image) such that it fills the whole 1:1 frame
  4. Change that background to reflect how you want the bars at the side (or top and bottom) to look. The usual choices are black, white, or a blurred version of the original image
  5. Done – your image's dimensions will be changed to 1:1 ratio, with your background visible either at the sides or the top and bottom
