Enlarging images is not as easy as it seems. Quality is lost. But artificial intelligence wants to fill in the gaps to improve the quality of your photos.
It must have happened to you once. You have an image, you want to enlarge it, but the result is disastrous. And it is not the same to reduce a photograph digitally than to increase it. In the second case, you have to fill in the gaps left by pixels missing. Something that seems silly but has a lot of importance at the time of print or publish on the web.
In the second case, the screen quality it’s getting bigger. Hence a low-quality image is seen more than in the past, so photographs published today have to be of higher resolution than a few years ago.
Professional tools have over time improved the task of enlarging images by providing algorithms that fill the gaps in a enlarged image so that you hardly notice that the original photograph was smaller. And lately, this task goes through artificial intelligence.
Here are several examples of projects that allow enlarge images using artificial intelligence. You just have to indicate the photograph in question. The AI will do the rest.
AI Image Enlarger
Available as an app for Windows, macOS, iPhone and Android, AI Image Enlarger you can also freely from your own website. Its operation is as simple as drag and drop the pictures you want to enlarge.
In principle, you can enlarge images up to 2, 4 and 8 times its original size. Of course, for free you can only work with files of a maximum of 5 MB and a resolution less than 1200 x 1200. If you need to use files of more size or resolution, you will have to go to the checkout.
AI Image Enlarger it gets along well with JPG, JPEG and PNG images. In addition, the process is very fast, so you will get the result in seconds.
Similar to previous tool, bigjpg it offers its services both from its own website and from its applications for Windows, Mac, iPhone and Android. Using what is translated in Spanish as “Deep Convolutional Neural Networks”, its objective is to enlarge images without losing quality.
bigjpg supports images up to 10MB in size and with a resolution not exceeding 3000 x 3000 pixels. In his questions section, he says he gets along better with drawings and illustrations that with photographs, but he can with both. You can enlarge 2 and 4 times its original size without registration, and up to 8 and 16 times with registration. It is also possible to choose the level of noise reduction.
Otherwise, you can use with or without registration. In the second case, you will have to keep the tool open while working if you want to download the resulting photo. As for the duration of the conversion, it does not specify a specific time. With an image of 1200×674 of 102 KB, I enlarged 4x with medium reduction and it indicated me about 6 minutes. In practice, it did not reach half a minute.
Since there are no two without three, here goes Deep-Image, another online service for resizing or enlarging images. On this occasion, you will enlarge 2, 3 and 4 times its original size.
Deep-Image it allows you to upload your own images and use photos from Google Drive. Supports the usual formats, JPG and PNG. After the conversion process, it generates an image of a maximum of 25 megapixels.
For free you can work with up to 5 images. From there, each image has a cost of 9 cents, so you can buy conversion packages.
