A lot of people don’t know, but the speed of loading a website is one of the main SEO factors that Google takes into account for ranking.

In this content, you will understand how this process works and find out how to compress or compress images and photos – in fact, you can do this completely online.
At the end of this post, you will have the information you need to have a faster website and thus attract more visitors. Follow!
What is image compression
Compressing images means making them lighter, without necessarily losing quality. Technically, compaction is linked to the compression process.
Let’s start from the idea that an image is a set of data and pixels, right? Within each image file – be it JPG, PNG, GIF or any other – there is repeated information.
What compression does is, precisely, remove this redundant data, making the image less heavy. Interesting, isn’t it?
To be clearer, let’s look at an example. Imagine a blue pixel composing an image of the sky. It is likely that the same color will appear again within the same photo.
So, why not save the value of that pixel only once, reproducing it for similar ones?
This prevents the file from having several identical pixels repeating itself, which would increase the loading time. Therefore, the compression process is quite intelligent, as it is an optimization.
It makes it possible to compress images without loss of data, or with very small losses, which are not even perceived by the human eye.
Anyway, if you still have doubts about whether it is worth compressing images, read the following topic. In it, we tell what Google itself says about the importance of knowing how to create a website fast.
What Google says about page speed
If the speed of loading a page was already important on the desktop, today, on the smartphone and mobile devices, it is essential.
This is because the user can do a search in the middle of the street or even while in traffic – for example, to search for a store or restaurant. So, the answer needs to come quickly.
According to the Official Google Webmaster Central Blog, it is not today that speed is one of Google’s ranking factors for mobile searches.
Since 2010, the most agile sites receive better positions on cell phones and mobile devices. Before that, this factor was already taken into account for desktop searches.
Not to mention that Google dedicates great efforts to make sites worldwide faster and faster. Want an example?
They themselves launched the Accelerated Mobile Pages (AMP) project, an open source initiative to create pages that load in less time on mobile devices. Sites that adopt this model are highlighted in searches, increasing the clickthrough rate.
In other words, it is natural that the largest search engine on the Web prioritizes fast pages. In addition, Google itself offers tools to test the speed of your site, such as Page Speed Insights.
As we mentioned in the introduction to this article, compressing images is one of the easiest ways to have a fast website.
So, how about finding out how to do this and achieve better positions in organic searches with your content marketing strategy? See below.
7 sites to compress images and photos online
Since reducing the weight of images is such an important factor for ranking well, nothing better than knowing some tools that will facilitate (and a lot!) This work. Below, we list 7 sites to compress images and photos online.
Favorite of many people and 100% free, the TinyPNG platform is ideal for those who work a lot with transparent background images and needs great quality, which is the case with PNG files. Still, despite the name, the site allows you to compress other file formats.
It is possible to upload up to 20 images simultaneously, with a maximum weight of 5 MB each. This also speeds up the process a lot.
Finally, the solution has plugins for WordPress and Magento, which can be integrated with your blog or e-commerce.
Following an idea similar to the previous tool, JPEGmini is another platform that allows you to compress images online for free.
Its great advantage is that you can compare the compressed file to the original before downloading. That is, it is ideal for those who still have a foot in relation to quality.
Here, there is also a paid plan that allows you to upload larger files (up to 50 MB). In addition, the premium version has integration with Adobe Lightroom, software widely used by photographers.
3. Compress PNG
Just like the previous options, Compress PNG has a web interface so you can compress images online. It is possible to upload up to 20 files at the same time.
After compression, you can download all of them in a compressed file. Despite the name that says “PNG”, the software also gives you the option to work with JPG, JPEG and even PDF files.
The previous tools are quite minimalist and go straight to the point, simply focusing on image compression. But, if you want to edit the photo a bit before compressing, iLoveIMG offers this option.
With it, in addition to compacting, you can crop and resize images. The platform also has the option of converting the file from other image formats to JPG, or from JPG to others.
Another interesting point is the possibility of upload images via Google Drive and Dropbox. That is, it is a good alternative for those who use these services and still want to give a “final touch” before compressing.
When working with images, not everything is 8 or 80. In fact, there are several levels of compression that can be used.
The Compressnow tool stands out, precisely, for allowing you to choose the percentage of compaction you want to apply (from 0% to 100%).
Best of all, the platform already shows a preview of how the image will look after being compressed. Excellent, isn’t it?
Unlike the alternatives already mentioned, the Kraken platform allows you to work with 2 types of compression.
Lossless (no data loss)
Ideal option for those who need maximum quality. It is useful, for example, for those who want to provide printable images.
This compression mode is often used by photographers and deals with file formats that have more features, such as PNG and TIFF.
Lossy (with data loss)
Ideal for most uses and especially suitable for the Web, this compression results in a small loss of quality.
But don’t worry: the drop in the pattern is so small that the human eye can’t even notice it.
The big advantage is that, in lossy, you can optimize some images by up to 90%, making them much lighter. The most used formats here are JPG, JPEG and GIF.
In addition to optimizing images directly in the browser, Kraken has a WordPress plugin. With it, you can do bulk optimizations, even from already published images.
The only obstacle is that the free plan allows uploading images with a maximum of 1 MB. Paid plans, on the other hand, offer differentials such as cloud storage and image resizing.
7. WP Smush
WP Smush is another platform that operates on the freemium model, that is, it has a free version and pay methods. It is a plugin and, therefore, its use is focused on WordPress.
Its great advantage is that you can optimize all images with the autocompressor, including old ones that have been in your directory for some time. All of this is done with a few clicks.
That way, the entire site will be faster, not just the new pages you create going forward.
In relation to the paid version, the main benefit is the unlimited autocompressor, while in the free version, there is a limit of 50 images of up to 1 MB at a time.
It is up to the user to assess their need and choose the alternative that fits their current context.
As we’ve seen, compressing images can dramatically decrease your site’s load time. And one thing is certain: both Google and users prefer fast sites.
So, the next time you upload some photos to your content, don’t forget to compress them first. This process can be done online, takes just a few minutes and will make a big difference in your ranking. Try it!
