Resize Before Upload

WordPress creates multiple thumbnail sizes from every upload. Resize large source images first so the generated thumbnails are not bloated.

WordPress supports WebP natively. Convert images to WebP before uploading for smaller media files.

Rename images before uploading. A file named blue-widget-product-photo.webp helps search engines understand the content.

Resize JPG, PNG, WebP, and AVIF images by width, height, percentage, or preset directly in your browser.
