Changing image size (scaling and resampling)

In Affinity Photo 2 there are options to change a document's or image's pixel dimensions and/or print resolution.

You can change the 'size' of an image by scaling or resampling it. These can be undertaken independently or simultaneously.

Scaling

Scaling will embed a specific print resolution into an image's metadata to force it to print at a specific dpi (e.g. 300 dpi). The image's pixel dimensions remain unaffected.

Resampling

Resampling will do one of the following:

When you resample an image, you have the option to:

Resampling may be carried out to:

More To scale an image:
  1. From the Document menu, select Resize.
  2. On the context toolbar, ensure Resize is set to Document.
  3. Absolute Size Disable Resample.
  4. DPI Change the DPI to control the number of pixels (dots) per inch when your document is printed. Set higher values (e.g., 300dpi) for professional printing.
  5. Tap the check to resize.

You will see no change in the image on the page as this procedure only affects the image's metadata.

More To resample an image:
  1. From the Document menu, select Resize.
  2. On the context toolbar, ensure Resize is set to Document.
  3. Absolute Size Enable Resample.
  4. (Optional) Select a different measurement unit from the Units menu.
  5. Width Height Adjust your document dimensions using the Width or Height slider (adjusting either will maintain the document's original aspect ratio by default). To resize the width and height independently, disable the lock icon (to unlock) on the context toolbar before using the sliders.
  6. DPI Change the DPI to control the number of pixels (dots) per inch when your document is printed. Set higher values (e.g., 300dpi) for professional printing.
  7. Select a Resample method from the pop-up menu.
  8. Tap the check to resize.
