Photo Resizer: How to Change the Size of an Image for Free

There is no shortage of reasons to resize a picture: you might want to change its dimensions for a social media post, highlight part of the frame, reduce the size to meet an upload limit, or free up some memory space on your phone.

In this article, I’m sharing how to use a free online tool called Kapwing to change the size of your photos to meet your needs. You can use Kapwing on any iPhone, Android, PC, or tablet, and you can make additional edits to stylize your pictures. To begin using the free online photo resizer tool, follow these 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, etc.) and upload them to Kapwing by pasting the image URL. If you want, you can click Google Drive to sign in and upload photos from your account. 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.

To upload your content, just go to and click Start Editing. Once you’re in the Studio, 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 of your content has been uploaded into the Kapwing Studio, it’s simple to scale your photo with preset dimensions. To choose from the most common sizes, click one of the options in the Output Size area of the menu on the right-hand side of the window.

Alternatively, you can click Custom and enter an output size to shrink or enlarge an image. You can also try out the standard dimensions listed in the menu to resize an image for Instagram, Facebook, or LinkedIn. Below is an overview of your 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 2560 pixels.

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 picture before downloading.

Step 3: Publish & Download

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

When your picture is finished processing, click Download from the right side of the screen to save your JPEG. If you're on a smartphone, long-press on the video to download it to your camera roll. If you're not signed into a Kapwing account, sign in or sign up using your Google or Facebook account – once you've signed into a Kapwing account, the watermark in the lower right corner will be removed from your final image.
