There's no shortage of reasons to resize a picture: you might want to change its dimensions for a social media post, focus on just one part of the image, upload it somewhere that has a file size limit, or simply free up some memory space on your phone. You may even have specific X&Y pixel dimensions in mind (for something like a wallpaper image) or you might just want to change the aspect ratio to avoid awkward cropping.
But there aren’t many easy ways to specify and change the exact size of your photo. Built-in apps on your phone and computer might only let you click and drag the corners of your photo so you can't see its aspect ratio. Online resize tools probably only include a few standard image sizes, and may not allow you to reposition your photo within a different aspect ratio. It might seem like the only way to resize your image with all the tools you need – cropping, resizing, and changing dimensions – is to use a large or expensive desktop app.
In this article, I’m going to show you how to choose the exact size, aspect ratio, and cropping you want for your photos, for free & online. I recommend using Kapwing, an online multimedia editor that works on computers, phones, and tablets, and allows you to make simple & advanced edits in a fraction of the time you would use in a desktop app. To resize your photos, you’ll need to know just three steps:
- Upload Your Photo to Kapwing
- Choose Your Output Aspect Ratio/Exact Dimensions
- 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.
To upload your content, just go to Kapwing.com and click “Start Editing.” 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!
To see some other options, or to enter precise pixel 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 few options:
- To use a different preset aspect ratio, click on one of the options under "Popular Sizes." You can adjust to square, Instagram/Facebook/Snapchat 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, neither side can be larger than 1920 pixels.
- If you want to resize your picture, but would like to keep the same dimensions, 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.
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 cropping, filtering, adding text, overlays, audio, shapes, text animations, and more.
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 begin processing your resized image, and it will be ready to download in under a second!
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 picture 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.
