How to Resize Images in Affinity Photo

It’s impossible not to have to resize images. You can’t upload on your website or online gallery full-size images, to begin with, because of limited storage space and copyrights protection. Then, each social media platform requires a different image size. Last but not least, your clients may ask for a specific image size for print or web.

Although you can’t escape this mandatory and repetitive task, you can choose to do it using your favorite photo editor, for example, Photoshop CC. Check out how simple and efficient is resizing images in Affinity Photo.

Step-by-Step: How to Resize Images in Affinity Photo

Affinity Photo allows you to resize an image in four simple steps. The entire process takes only a few seconds.

Step 1: Open the Image in Affinity Photo

Go to File -> Open and choose the image you want to resize.

Step 2: Go to Document -> Resize Document…

To open the resize window, go to Document -> Resize Document… or press Ctrl+Alt+I. Affinity Photo provides a set of parameters for you to set up before resizing your photo.

Step 3: Set Up Resizing Parameters

The set of parameters includes the new dimensions of the image, the unit you want to use (i.e. pixels, points, millimeters, etc.), the resolution of the new image, resample method, and whether you want or not to resample the image.

You also have to decide if you keep the aspect ratio of the image or you change it. Use the small lock between the new dimensions to constrain the aspect ratio or allow for it to change. To create a consistent body of work, use the same aspect ratio for all your photos or, at least, for a series of photographs.

Step 4: Choose New Dimensions

After setting up the other parameters, you only have to choose the new dimensions and press Resize. Affinity Photo displays the size as width and height (from left to right).

How to Resize Images in Affinity Photo at Export

You can start the editing workflow by resizing the image to match its purpose. And, you should do it this way when you enlarge photos for print because going for larger dimensions can affect image quality and require some corrections. However, when you need smaller sizes for web or social media, you can resize images at the end of the editing process. More precisely, you can resize them at export.

Step 1: Open an Image for Editing

Go to File -> Open and choose an image you want to use for your editing process. Then go through your editing process and prepare the photo for publishing.

Step 2: Open the Export Window

Go to File -> Export… or press Ctrl+Alt+Shift+S to open the export window. Among other export settings, it includes the width and height of the exported image. Like the dedicated resizing tool, the export settings also give you the option to keep or alter the aspect ratio. To make sure you export and resize the entire image, select ‘Whole document’ in the Area list of the export window.

Step 3: Export the Image with New Dimensions

Press Export and choose a name and a location for the new image. You’ll notice that Affinity Photo has resized the image before exporting it. However, only the exported image has been resized. The image you are currently editing has the same dimensions as it did before the export.

Resize Images with Macros

Even if it doesn’t take a lot of time to resize an image in Affinity Photo, it’s always better to be able to do it faster and more efficiently. Therefore, you can use a macro to resize images. A macro is a pre-recorded set of actions you can apply instantly to an image.

Go to View -> Studio -> Macro to open the Macro panel. Then start recording by pressing the round red button. Do all the steps required to resize the image using your preferred settings. When you finish resizing, stop recording by pressing the square button from the Macro panel.

Save the macro by pressing Add to Library and providing a name and a category for the new macro. Find a meaningful name, such as a name that includes the resizing parameters. Now every time you need to resize an image using these parameters, you can use the macro.

Step-by-Step: How to Resize the Canvas in Affinity Photo

The Resize Document… option allows you to change the dimensions of the image without noticing any difference in the editing workflow. The new image will have smaller or bigger pixel dimensions and will take less or more storage space. But in terms of editing, nothing changes. However, sometimes you’ll need to change not the size of the image, but the size of the canvas. For example, you’ll need a larger canvas to create a collage or a book cover for your next photo album.

Step 1: Open an Image in Affinity Photo

Go to File -> Open and choose an image you want to use for your editing process.

Step 2: Resize the Image

Use the Resize Document… option to resize the image to new dimensions.

Step 3: Go to Document -> Resize Canvas…

Go to Document -> Resize Canvas… or press Ctrl+Alt+C to open the settings window for changing the size of the canvas. Affinity Photo allows you to set the new dimensions (width and height), decide to keep the aspect ratio or not, choose the unit to use, and choose the reference point of the new canvas (i.e. the anchor). You have nine points to use as reference so you can position the canvas relatively to the image. To select an anchor, click on one of the little blue squares. Then, press Resize and continue editing your project.
