Do you want to know how to adjust and compress high-volume images without losing quality? On the right page. Let’s take a look at how to optimize photos and improve website performance while saving time. Image compression is a process of reducing the weight of an image by reducing its size without compromising its quality. This article introduces the important reasons for adjusting and compressing images, and how to perform them easily without affecting the quality. Jump in! One of the biggest trends in web design is to publish large and beautiful images on websites. However, for web performance, these large images are often the main reason for the slow down of the site. If not implemented properly, the file size of these images may increase, increasing HTTP requests to the browser.
Here are some benefits of compressing large photos: Google said that the compressed image can speed up and provide the best user experience. Google pagespeed insights suggests that when the loading time needs to be improved, appropriately adjust the image size (especially mobile), delay the screen image (apply delayed loading), and use a new generation format (such as webp). Image recommendation (extraction) of Lighthouse – source: adjust and compress the size of PSI image, including core performance report, which can reduce the page size defined by Google and improve performance indicators. Optimizing images means that visitors need to wait for time to interactive metric and enhanced cognitive speed (first contentative paint and largest contentative paint Metric) before interacting with the website. Smaller image file sizes use less bandwidth. The web and browsers will certainly highly evaluate this! Optimized images can achieve maximum byte savings and performance improvement on the website. The fewer bytes the browser needs to , the smaller the bandwidth competition and the faster the loading time. HTTP requests for high-capacity HD images may have a negative impact on performance, so to speed up the WordPress site, you must reduce HTTP requests. There’s no need to improve the performance of image compression, right? The goal is to obtain the results of mass and optimal balance, as shown in the following example.
Male no compression JPEG – 400 KB male compression (quality unchanged) JPEG – 170 KB male next. How to reduce the image size without losing quality? The two main factors that need to be considered are the type of compression (lost and lossless) and file format (PNG, JPEG, PDF, etc.) to be used, that is, the method of massive scaling and compressing images (PNG and JPEG). You can see the effect of format on image size below. Format versus file size – source: selesti. Maximum utilization of COM PNG and JPEG images. Some help you perform all these tasks yourself (such as the WordPress plug-in), while others allow users to perform optimizations (such as Photoshop).
The following is a list of common tools that can be used to compress a large number of JPEG or PNG images. We divide them into two categories: category #1 – starting with the first category of image optimization web tools and software that heavily optimize high-volume PNG and JPEG images #2 – WordPress plug-ins that heavily adjust and compress high-volume PNG and JPEG images. Category #1 – image optimization web tools and software for massive optimization of high-volume PNG and JPEG images
Final list of software and online tools that can be used to resize and compress.
Batch compression of parity photos, PNG and JPEG images. File > create mobile batch jobs with new batch jobs – source: YouTube channel method 2. Upload all photos that need to be compressed in large quantities, and select the most suitable format as needed. Batch save jobs – source: YouTube channel method 3. Define new quality. (70 is a good number to maintain good quality) maleimage compression and reduction (quality 70) preview (on MAC) – a lot of image resizing (no compression). Use preview to open all images. Go to Selection Tools > size, and then select a new image size. The software preview is completed! The result is smaller.
Mass image compressor – an image compressor and converter tool used to optimize the spot deployment of websites. Large capacity image compressor configuration gimp – free image editor widely used for Mac and windows. Kimf also provides a so-called deployment mode, which can perform image processing in other formats such as PNG, JPEG and GIF or PDF. You must and install a free extension called batch image manage plugin (BIMP). The steps are really simple. Image placement operation – source: adjust and compress the size of windows Club Photoshop – PNG and JPEG images (affecting quality and relatively expensive). Open Adobe Photoshop and select File > script > image processor. Click Select folder to select a folder that contains images. To reduce the size, adjust the settings. In the quality field, select a setting between 1 and 12 (preferably no less than 6). Click Run task. Note: Photoshop’s learning curve is steep, so if you’re interested, Photoshop lists 10 alternatives to image optimization.
If you want to save time, you don’t have to deal with all formatting and compression manually. Fortunately, some plug-ins automatically perform some of these tasks! Navigate to the second category, WordPress plug-ins. Category #2 – the WordPress plug-in massively scales and compresses high-volume PNG and JPEG images, and then uses one of the WordPress plug-ins to massively compress high-volume images. Imageify (free plug-in) optical JPEG and PNG compression (small PNG) ha ha short pixel resmush. Do you want to know what is the most suitable word press plug-in for it projects? We did a lot of work for you and compared the best image compression plug-ins (using real scenes). All of them provide a package of optimization, and most of them convert images to webp format according to Google’s recommendations. Use imageify to conduct a case study and highlight the steps to follow to optimize the large image.
Male imageify does not lose quality. The method of compressing large images. Imageify can adjust the size and compress a lot without exiting word press. Let’s look at the dashboard of imagify and get the look and feel of the batch optimization function from the media > batch optimization menu.
