Let’s find out how to optimize images for the web while maintaining image quality

How to improve the quality of an image

Posting high quality images on the internet is now a standard that one cannot do without. If we look around, we can see how the overall quality of photo and video content has increased in level compared to a few years ago.

Whether it’s because of the increasingly powerful mobile cameras or the general commitment that creators use to their productions, it’s no longer acceptable to publish low quality photographs online.

Of course, the same concept also applies to printing. Imagine you have to print your child’s picture for school and it gets grainy or blurry.

Fortunately, today it is possible to improve the quality of an image directly online, thanks to free apps, made specifically for this need. Let’s see how they work together!

How to optimize images online

When we have an image that is too small or perhaps not very keen to be published online, we have to expose it to the so-called image optimization process.

When we talk about optimization, we typically refer to the process that improves the overall image quality based on the following criteria:

  • Increased image resolution. Image resolution refers to the density of the pixels it is made of.
  • Perceived quality at image level such as brightness, sharpness and color saturation.
  • Optimization of the final weight of the file. If an image is overweight, it may not be possible to upload it online. For this reason, when publishing images on the Internet, always find the right compromise between image quality and final weight.

How do you change the resolution of an image?

How to change the resolution of an image

Changing the resolution of an image is very simple. There are many online tools created specifically for this task.

Whether you need to optimize images for a website or for printing, instead of using complex photo editing software, you can turn to specific apps to enhance images online for free.

The first step, therefore, is to choose the online app that best suits your needs and upload the image to enlarge or enhance. The selected app will, using artificial intelligence, increase the resolution of the image in a few moments and return the image optimized for the intended purpose.

What is the resolution of an image?

What is photo resolution

Image resolution can be defined as the level of detail in an image. Raster images are made up of a series of pixels, where resolution means the total number of pixels along the width and height of the image, expressed in pixels per inch (PPI).

The higher the PPI value, the greater the detail and the better the print quality, whether it is a family photo to be framed on the wall or a photo to be uploaded to the web.

What are apps to improve the quality of an image

Thanks to the use of artificial intelligence, apps for improving the quality of images are able to enlarge images without any problems in a few moments. However, we must clarify that not all artificial intelligence algorithms are the same, some are certainly more advanced than others and therefore generate more accurate results.

We have compiled a list of the most used apps to optimize images and increase their resolution for the web or for print.

Image Upscaler

Image Upscaler

By visiting the link it.depositphotos.com/upscaler.html you can try the image optimization tool created by Depositphotos. Thanks to its powerful artificial intelligence algorithm that analyzes millions of images every day, it is possible to increase the resolution of the images without losing the quality with a few clicks.

To increase the resolution of an image with Upscaler, simply upload the image to the site using the appropriate button or drag and drop the image directly onto the site’s interface. The magnification is fully automatic in a few seconds. Before downloading the image, you can compare before and after the result.



Application dedicated to online image enhancement. With this app you can enhance photos and enlarge them according to your needs. Photo is also an image editor, so you can also intervene in hue and saturation and other parameters for image enhancement. There is also an automatic function that with a single click restores greater gloss to the image.

Let’s improve

Let’s Enhance improves the quality of an image and allows you to easily enlarge it. The tool is very easy to use and like the others can be used with very few clicks.

It is possible to edit up to 5 images for free and to get enlargements up to a resolution of 64 megapixels.

Image Upscaler

Image Upscaler is an online tool that allows users to resize images up to 4 times. Powered by AI technology, Image Upscaler is capable of resizing images without losing quality. The tool also includes an image analysis feature and adds the lost details to make the image appear more attractive.

In terms of sizes, the tool supports a maximum image size of 5 MB, with a limit of 2500 pixels. You can also use the same tool to remove blur from images, improve sharpness, and remove JPEG artifacts that occur after image compression.


This tool offers an option that many free image resizing tools do not offer. You can crop a specific part of the image and resize it. This can be useful if there are too many white spaces around a product or if you want to remove someone from an area of ​​the image. You can also rotate the image left or right.

Simple Image Resizer

With this online app you can select the image, choose whether you want to enlarge it according to the desired size or percentage and determine the number of pixels. However, you need to be careful as the image format is not kept by default. This can lead to a distorted or strange looking end result.


Today, unlike a few years ago, it is possible to optimize images for the web directly online for free with the help of dedicated apps that use artificial intelligence.

From now on, we can increase the resolution and enlarge our images with just a few clicks as true graphic designers, but let’s face it, in a much faster and easier way!
