There's no shortage of reasons to resize a picture: you might want to change its dimensions for a social media post, focus on one part of the frame, upload it somewhere that has a file size limit, or free up some memory space on your phone. You might have a specific pixel value in mind or might want to change the aspect ratio. But there aren’t many easy ways to specify and change the exact size of your photo.

In this article, I’m going to show you how to use a free online tool called Kapwing to choose the exact size you want for your photos. Kapwing works well on computers, phones, and tablets, and gives you the functionality of a high-powered editing software without requiring you to download any apps. To resize your photos, you’ll need to know just three steps:

  1. Upload Your Photo to Kapwing
  2. Choose Your Output Aspect Ratio/Exact Dimensions
  3. Publish & Download!

Step 1: Upload Your Photo to Kapwing

You can find your photos anywhere on the Internet (Facebook, Instagram, Twitter, Google Images, Google Drive, etc.) since Kapwing lets you easily import pictures from almost any site. All you need to do is copy the link to the photo or its webpage! And if you’ve saved your pictures onto your device, just make sure you know where they’re located. If you're uploading photos from your own computer, it's a good idea to have your file browser open, so you can click & drag your content into the Kapwing Studio.

Upload a photo to the Studio easiloy by dragging & dropping a file!

To upload your content, just go to and click “Get Started.” Or, if you're already signed in, click "New Project," then "Start with Studio." This will take you to the Kapwing Studio, where you can use all of Kapwing’s editing tools in one place. Once you’re in the Studio, either select “Click to Upload” and search in your file browser, or paste the link to the picture you want to upload. If your picture is easily accessible, you can just drag & drop it into the Studio window, and it will upload automatically.

Step 2: Choose Your Output Aspect Ratio/Exact Dimensions

Once all your content has been uploaded into the Kapwing Studio, it’s simple to resize your photo or choose your exact output dimensions. To choose from the most common output dimensions, just click one of the options in the "Output Size" area of the menu on the right-hand side of the window!

Resize your photo with just one click!

To see some other options, or to enter precise dimensions for your picture, just click "Custom Size" from the same menu on the right-hand side of the Studio. In the custom resize window, you have a ton of options:

  • To use a different preset aspect ratio, click on one of the options under "Popular Sizes." You can adjust to square, Story-sized (9:16), landscape (16:9), 5:4 or 4:5.
  • If you'd like to fully customize your picture's dimensions, unlock the aspect ratio and enter the width and height that you want. There are no lower limits, so you can make your images as small as you need! At the moment, the upper limit for either dimension is 1920 pixels.
  • If you want to resize your picture, but would like to keep the same aspect ratio, make sure the aspect ratio is locked (you'll see a purple button that says "unlock aspect ratio") and enter the exact width or height that you'd like. The other dimension will be calculated so the aspect ratio remains the same.
Enter your photo size in exact pixels, or scale your picture based on preset dimensions!

Once you've adjusted your picture's size and dimensions,  exit the custom resize window. While you’re in the Kapwing Studio, you can make any other image edits that you want to, like adding text,  overlays, audio, shapes, text animations, and more. Creators can also crop and filter their resized video before downloading.

Step 3: Publish & Download

Once you've edited your picture to perfection and selected the optimal size and dimensions, click "Publish" in the upper right-hand corner. Kapwing will automatically work its magic and your picture will be ready to download in no time!

Your resized photo is just a click away!

When your picture is finished processing, click “Download” from the right side of the screen. If you're on a smartphone, long-press on the video to download it to your camera roll.

Creators can also "Edit" to make changes to the image's size or share the image directly to social media. To remove the watermark, sign in and save the image to your workspace.
