Understanding Media Library Uploads<\/h2>\n
<\/div>\n

OPTe\u2019s multisite platform has system-wide optimizations for the media library to ensure optimal performance and efficient storage utilization for all sites.<\/p>\n

While the general maximum upload size per item is 8 MB, we have specific limits for certain file types to prevent overloading media storage over time. For example, PDF files have a maximum upload size of 5 MB. This approach helps us maintain a sustainable hosting environmen<\/a>t and is one of the ways we optimize WordPress for our customers.<\/p>\n

Optimizing Images for Web & Server-Side Compression<\/h3>\n

When it comes to image files like JPEGs and PNGs, we recommend optimizing them for the web before uploading<\/strong><\/a>. Ideally, these files should be under 300 KB to ensure fast loading times and efficient storage use. While larger image files (3-5 MB) might sometimes be uploaded, it\u2019s generally best practice to process them for web use first. Using image editing software or online optimizers before<\/em> uploading gives you the most control over the final quality and dimensions, ensuring they are perfectly suited for web display.<\/p>\n

Built-in Compression via WP Smush Pro:<\/strong> Our platform utilizes WP Smush Pro<\/strong>, which includes robust server-side image compression functionality. When you upload images, Smush Pro automatically processes them, applying advanced compression techniques to significantly reduce file size without compromising visual quality. This happens seamlessly in the background, minimizing the impact on your site’s performance during upload. WP Smush Pro handles lossless, lossy, and even “Ultra Smush” compression, and can convert images to modern formats like WebP for even better performance. For those who want more control, the plugin also offers options to customize compression levels and settings.<\/p>\n
