Resize

As explained in WordPress Power Toolkit: Harness AI to build next-level websites

Image resizing is the process of changing an image's pixel dimensions while optionally preserving its proportions.

Image resizing changes an image’s pixel dimensions so it fits its role on a website. Preparing images before uploading them can reduce unnecessary file size and support faster page loading. section 8.4

Use this practical preparation workflow:

  • Identify the image’s purpose, such as a logo, ordinary page image, or full-screen visual. section 8.4
  • Reduce dimensions and usually resolution from print-oriented settings before uploading to WordPress. section 8.4
  • Use a dedicated photo editor rather than relying on WordPress for quality resizing or resolution changes. section 8.4

A phone photo prepared for the web

An iPhone 12 image measuring 4,032 × 3,024 pixels can be far larger than a typical web image. Resizing it before upload can reduce a roughly 31 MB PNG toward a more suitable file size. section 8.4

Figure 8.7 When you crop a low-res image, the result can be serious degradation like this pixelization.

Compare how cropping a low-resolution image can produce visible pixelization. section 8.4

Use the visual reference to identify controls for changing image size and resolution. section 8.4

How WordPress Power Toolkit: Harness AI to build next-level websites covers it

How deep it goes
Explains dimensions, PPI, file size, cropping risks, and tool choice without detailing a complete editor-specific procedure.
Examples
Uses an iPhone 12 image, PNG size comparisons, website image roles, and visual examples of pixelization and size controls.
What it assumes
Assumes a website image-upload workflow and introduces the distinction between print-oriented and screen-oriented resolution.
What you can do after
Apply it via Photoshop, Paint.NET, or GIMP to prepare appropriately sized images before uploading them to WordPress.
How it connects
Connects image resizing with PPI, file size, page load speed, WordPress, cropping, and photo-editing applications.
