How to Bulk Edit WordPress Images for the Proper Size

At present, the image has become a critical component for any website content. With it, you can express your idea in a much more vivid manner and can add more fun into your articles. When uploading an image, you need to consider the image quality, format and beauty. Furthermore, you have to think about the image size that can fit your webpage design properly and do not consume too many of your disk storage.

Surely, you can edit the image size using some special tools such as PhotoShop before uploading to your website. However, if you have changed your WordPress theme or have modified the website design, you have to edit all your existing images with the proper size to fit the current style. Frankly speaking, the manual method for doing so is really time-consuming. In this case, we’d like to introduce how to bulk edit WordPress images to achieve your preferred image size.

Option 1 – Use the Bulk Resize Media Plugin

If you want to achieve the bulk editing of your images for some other size options, the easiest way is to use the related plugins. Here, we firstly recommend you to use the Bulk Resize Media plugin. This user-friendly plugin allows you to resize the huge and large images uploaded on your site. Also, you can make sure that all the new images will be uploaded with the maximum uploading size.

To use this plugin properly, you do not need to set up some complicated settings. Instead, you can click the Media > Bulk Resize button directly. Here, you need to make the decision for the following parts.

Bulk Resize Media

  • The maximum width and height for images that are displayed in your posts, pages and any custom post type.
  • The maximum width and height for those uploaded to your Media Library, theme headers, website logo and background directly.
  • The exact value of JPG image quality. Note that the default value for WordPress site is 90.
  • Decide whether to convert BMP to JPG or not.

After finishing these settings and save the changes, you can move down to the following area. Here, you can search all the existing images that come with the larger sizes than your determined limit.

From the listing result, you can tick the checkboxes for all the found images, and then, click the Resize Checked Images button. This way, you can resize them in bulk to free your disk space.

Option 2 – Use the Simple Image Sizes Plugin

The second plugin we’d like to recommend is the Simple image Sizes. This plugin allows you to easily create some custom image sizes and applies to your target size with much ease.

To use it, you only need to click the Settings > Media button. Here, you can find a lot of image sizes that can determine the maximum width and height in pixels. The default sizes are for the thumbnail images, medium-size images, large-size images and medium-large images.

Here, you can decide the exact dimensions for each size option and determine whether to crop the images or not. Also, you can click the Add A New Size button for generating the new size option.
