What you'll achieve
You will have the photos loaded as thumbnails, one source photo selected in the preview, and the WebP output settings visible for review.
What you need
  • Web Image Optimizer Pro 2.0 on Mac.
  • A local folder containing the photos you want to prepare for WebP conversion.

Prepare a folder of website photos for conversion in one workspace. Web Image Optimizer Pro lets you examine the imported images and the intended output settings before running a batch.

  1. 1.Import a folder of photos

    Click Import Images and choose a folder of photos. The images appear as thumbnails in the left sidebar, ready to inspect together. The example batch contains three JPEG photos.

  2. 2.Preview an image from the batch

    Select a thumbnail, such as studio-founder.jpg, in the left sidebar. The central preview shows that photo along with its original dimensions, format and file size.

  3. 3.Review the WebP output settings

    Select another photo, such as coffee-bar-counter.jpg, to inspect it in the preview. In the Output Format panel, confirm that Format is WebP, review Quality (80% in this example), and check Preserve folder structure. The batch is prepared for conversion, but no files have been exported.

Tips

  • The thumbnails in the left sidebar let you compare source images without leaving the batch workspace.

  • Check Quality before converting: lower quality may reduce WebP file size but can also reduce visual detail.

  • Review Preserve folder structure if your output should keep the relative source folders.

  • Watch outThe screenshots cover importing, previewing and reviewing settings only. They do not show a completed WebP export.

  • Watch outAn optional file-size target is an estimate and not a guarantee of the resulting file size.
