This is Phiksel, the intelligent image optimization assistant for WordPress.
What is it
Phiksel is the only WordPress image optimizer that resizes and crops images to their exact required dimensions. When a page first loads, the plugin scans for images and calculates their precise required dimensions based on the page layout. It then resizes and crops each image accordingly.
These optimized images are cached and served to all subsequent visitors for optimal performance. This process occurs for every screen size, ensuring perfectly dimensioned images across all devices.
If you benefit from this plugin please consider writing a review! That would mean a lot to us.
Why do we need this?
Because the way images is handled in WordPress is not optimal. It relies on srcset, an HTML attribute that allows browsers to choose between different image sizes. While srcset is a valuable tool, WordPress’s implementation is basic.
Ideally, you’d manually provide images optimized for specific dimensions, considering factors like screen size, page layout, image placement, screen density, and image orientation. However, this is impractical due to the vast number of devices and their varying screen sizes.
WordPress attempts to automate this process by resizing uploaded images to a predefined set of sizes without cropping. This approach often results in suboptimal results. For example, if a landscape image needs to be displayed in a portrait orientation, WordPress will load the entire landscape image and then display only a portion of it, leading to wasted bandwidth and slower loading times.
Similarly, WordPress will almost never have the exact image size needed, forcing it to rely on a few preset sizes and choose the closest match.
Another issue is that when an image is too large, the browser needs to squeeze it, making it lose sharpness. An image with exact dimensions that does not need to be modified by the browser will always look much sharper.
In contrast to all of this, Phiksel is like having an assistant that creates pixel-perfect images for every scenario.
How it works
Pixel-perfect image sizes
Phiksel is the only WordPress image optimizer that resizes and crops images to their exact required dimensions.
Resizing and cropping on the fly
Resizing and cropping occur on the first page visit rather than during image upload. This allows Phiksel to know exactly what size each image should be.
Smart CSS understanding
Phiksel analyzes CSS images properties like width, height, object-fit, object-position, and aspect-ratio to perform the necessary image processing.
Responsive image for real
When the browser width changes causing the layout and thus the images sizes to change, a new image will be created for that specific case. This means you will always have pixel perfect image sized for every screen size.
Smart caching
Images are cached after creation for faster loading. The smart caching algorithm tracks when image sizes change and automatically generates new versions.
Effective lazy loading
When you visit a website, you only see a few images at first. Why load everything at once? Phiksel intelligently loads images just before they enter your viewport, making the page load faster and more efficiently.
100% page speed score
Achieve a 100% page speed score simply by installing and activating Phiksel. The plugin ensures you’ll pass the test without any issues.
Super lightweight, only 2.7 kb
Developed with a focus on performance and clean code, the plugin adds only 2.7kb of minified JavaScript to the website.
Local optimization
All optimization occurs on your own website. No third-party services or monthly subscriptions are required.
Unlimited images
Optimize as many images as you need and accommodate any level of website traffic. Unlike other services, there are no limits on usage.
Features
Set image quality
Phiksel is fine-tuned to provide the perfect balance between image quality and speed. Prioritize image quality or maximize compression for faster loading times – the choice is yours.
Optimize original image
Uploaded images can often be very large. Phiksel gives you the option to optimizes your images, significantly reducing their file size while preserving 98% of their original quality.
Empty image cache
When needed you can empty the image cache. You can also clear cache for individual images.
Exclude images
If you wish to prevent Phiksel from optimizing an image, add the class “phiksel-exclude” to the image element.
