Why cropping photos matters

Cropping is one of the most commonly used edits in photography. By cropping a photo you remove distracting elements at the edges, improve the composition and make sure the subject takes center stage. Whether you take photos for social media, a photo book or for printing, cropping instantly makes your photos better.

The great thing is that cropping a photo is very easy and doesn't require any special software. Both smartphones and computers have built-in tools for cropping photos. In this article we explain step by step how to do this on different devices.

Cropping a photo on iPhone

The iPhone has an excellent built-in photo editor that lets you crop photos quickly and easily. You don't need an extra app: everything is in the standard Photos app.

Steps to crop a photo on iPhone

Open the Photos app and select the photo you want to edit. Tap 'Edit' in the top right. You are now in editing mode. Tap the crop icon at the bottom (a square with arrows). You now see a frame around your photo with handles at the corners and sides.

Drag the corners or sides inward to select the part of the photo you want. You can also pinch with two fingers to zoom in and move the frame. When you're happy with it, tap 'Done' in the top right to save the change.

Using fixed aspect ratios on iPhone

For social media or printing you often want a specific aspect ratio. In crop mode, tap the aspect ratio icon in the top right. Choose from options such as square, 16:9, 4:3 or other standard ratios. The iPhone adjusts the frame automatically.

Cropping a photo on Android

Android phones have similar options, although the interface differs per brand. Most Android devices use Google Photos or their own gallery app with editing features.

Cropping in Google Photos

Open Google Photos and select your photo. Tap 'Edit' at the bottom (the slider icon). Then choose 'Crop'. You now see the crop frame. Drag the corners to select the area you want.

At the bottom you'll find options for fixed aspect ratios such as Free, Square, 16:9 and more. Tap 'Done' and then 'Save copy' to keep your cropped photo. Google Photos always makes a copy, so your original is preserved.

Samsung users can also use the built-in Gallery app. Open the photo, tap the pencil icon to edit and select the crop icon. It works much like other apps: drag the corners and choose a fixed aspect ratio if you like.

Cropping a photo on a Windows computer

Windows offers several ways to crop photos. The built-in Photos app is the easiest option for quick edits.

Using the Windows Photos app

Double-click a photo to open it in the Photos app. Click 'Edit image' at the top or press Ctrl+E. In the editing window, click 'Crop'. Drag the corners of the frame to select the part you want.

On the right you'll find aspect ratio options. Choose from Freeform, Original, Square or specific ratios for printing. Click 'Save as copy' to keep your cropped photo without changing the original.

Using Paint to crop

The classic Paint program is still available in Windows and perfect for simple cropping. Open your photo in Paint, use the selection tool to draw a rectangle around the part you want, and click 'Crop' in the menu. Save the photo via File and Save as.

Cropping a photo on Mac

Mac users have the excellent Photos app and Preview for cropping images. Both programs come free with macOS.

Cropping in Photos on Mac

Open the Photos app and double-click the photo you want to edit. Click 'Edit' in the top right. Choose the crop icon in the toolbar. Drag the corners of the frame or choose a fixed aspect ratio from the drop-down menu on the right.

You can also rotate and straighten the photo in this mode. Click 'Done' when you're happy with it. Photos on Mac saves edits non-destructively, which means you can always go back to the original.

Cropping in Preview

For individual image files, Preview is a quick option. Open the photo in Preview, select the area you want with the selection tool, and choose Tools and Crop from the menu. Save the file to keep the change.

Online tools for cropping photos

Don't want to install any software? There are excellent free online tools available. They work right in your browser on any device.

Popular options are iLoveIMG, Photopea and Canva. Upload your photo, use the crop tool and download the result. Do keep privacy in mind: your photo is temporarily uploaded to a server. For sensitive photos, you're better off using local software.

Tips for better cropping

Keep the rule of thirds in mind when cropping. Place important elements on the imaginary lines that divide your photo into nine equal parts. This creates a dynamic and attractive composition.

Don't crop away too much, because this reduces image quality. The more you crop, the fewer pixels remain. This is especially noticeable when printing at a large size. Try to choose a good composition when you take the photo.

Always keep the original before you start cropping. Make a copy of the photo or use software that works non-destructively. That way you can always go back to the original version later if you change your mind.

Cropping for specific purposes

Different platforms have different optimal sizes. For Instagram feed posts, square (1:1) or portrait (4:5) works best. Instagram Stories and TikTok use 9:16 (full-screen portrait). Facebook posts perform well at 1.91:1 or square.

Different ratios apply to printing photos. Standard photo sizes are 10x15 cm (2:3), 13x18 cm (about 5:7) and 20x30 cm (2:3). Check which size you are having printed and crop your photo to match, to avoid white borders or unwanted cropping by the print shop.

Frequently asked questions

Do I lose quality when I crop a photo?

Yes, cropping removes pixels, which lowers the resolution. For online use this is usually not a problem, but for large prints it can be noticeable. So don't crop more than necessary, and ideally shoot with the right composition from the start.

Which aspect ratio should I choose for Instagram?

For Instagram feed posts, square (1:1) or portrait (4:5) works best. Stories and Reels use 9:16 (full-screen portrait). Landscape photos can be posted at 1.91:1, but get less visibility in the feed.

Can I restore a cropped photo to the original?

That depends on the app you used. iPhone Photos, Google Photos and Mac Photos work non-destructively: you can always return to the original via 'Revert'. Apps like Paint overwrite the original, so make a copy first.

How do I crop a photo into a circle?

Most basic photo apps only support rectangular cropping. For a circular crop, use programs such as Canva, Photoshop or GIMP. You create a circle mask that makes the rest of the photo transparent.
