- Apr 08, 2020 Short of creating a new image of the same object in a higher resolution, there is no way to increase the resolution of an image. However, it is possible to use software tools to improve the image quality so that the pixelated image doesn’t look so bad. There are a couple of different ways to accomplish this task.
Sometimes you take the perfect photo, but it’s just too small to show all of the detail of the subject you were attempting to capture. There are a number of situations when you need to resize a photo. More than likely, you haven’t been all that impressed with the blurry results you achieve. When you want to make images larger without losing quality there are a few things that you need to understand.
Jun 05, 2015 Using one of the presets on Noiseless, I was able to greatly reduce the pixelation. Photo: David Pierini/Cult of Mac Noise is a kind of visual distortion and looks similar to the grain you find in. Pixelated image is especially common on smartphones, partly because camera technology is still poor on many mobile devices. But there is no photo editing app-integrated feature of removing pixelation. According to testing, several photo-editing apps have the ability to enhance photo quality and reduce this problem, like Adobe Photoshop Express.
Our basic guide to resizing images can help you avoid blurry images by providing information about what is happening when you resize photos, we’ll provide you with possible solutions and we’ll also provide 3 tips for higher quality enlargements as well. The second part of this article will discuss the various software solutions available for resizing images without sacrificing quality.
Basic Guide to Resizing Images
Just about any photo editing software available has the resizing option included, and that is because resizing photos is a pretty common task. Resizing is often necessary to save file space, in the creation of professional presentations like newsletters or PowerPoint presentations, inserting photos into documents, social media background images, and the list goes on. Resizing, especially enlarging, can create distortion or blurring of the photo. This issue can be avoided and we’re about to show you how.
Why do images lose quality when they are enlarged?
The first step in avoiding distortion when you make an image larger is gaining an understanding of what happens when a typical photo is enlarged. To understand what happens, you have to understand the concept of pixels.
Pixels and Bitmap
Bitmap is the most common image format used in photographs. In fact, when you purchase a digital camera or a camera phone, one of the specifications provided is a number like 3MP, 5MP, or 8MP. The MP stands for megapixels, which is made up of 1 million pixels. These pixels are combined to make up a bitmap image. If you zoom in really tight on a photo, you will see these entities in the form of squares. Each of these squares is mapped to a fixed location on the image, thus the term bitmap.
Pixelation
Resizing an image enlarges or shrinks each of the pixels inside the image. When you shrink the pixels, you see no loss of quality in the image, because the pixels become even less visible. However, when you enlarge an image, the pixels become more visible and their mapping becomes more pronounced. The blurriness or distortion that you see with an enlarged photo has become “pixelated.”
A good example of pixelation can be illustrated by taking a look at a mountain slope at a distance. At a distance, the trees create large patches of various colors and types of trees. As you move in closer to the slope, you begin to notice the detail and textures of individual trees rather than the patches of colors.
What’s The Solution?
Now that you understand what is going on and the various issues you are facing when you enlarge a digital image, you can start to find a solution. One of those solutions is to make compensation for each enlarged pixel in order to match its properties to the nearest pixels. This is called fractal interpolation or fractals and it is what produces higher quality enlargements. Most software programs utilize fractals to create enlarged images.
Interpolation
A great example of what is going on when you enlarge a digital image is to understand what it is you are asking your computer to do. When you ask a computer to enlarge an image, you are asking it to create a new image of your photo in a larger size. In essence, you are asking your computer to guess what that image and each of its pixels would look like if it was larger. Though some software apps do a better job of guessing and recreating the image, they still have to make a guess. The greater variation of guessing or prediction that has to be made will determine how much the image is degraded. Interpolation is the prediction method used to achieve quality enlargements.
Vector Graphics
Lossless is the term used for enlarging images without losing quality. Lossless is a compression algorithm, which preserves the integrity of a graphic image and it is used in vector graphics. To enlarge a bitmap image without losing quality, you have to generate it in its vector form, enlarge the vectors and then export them back to a bitmap image. Vector imaging or vector graphics is what most of the software applications used for enlarging images utilize to make images larger without losing quality.
Three Tips for Higher Quality Enlargements
Often, the image we need to enlarge is a bitmap image instead of a vector image, so that tends to create lots of problems when we do enlargements. Though you cannot quite produce an exact replica of the original image in an enlargement, there are certain techniques that can be utilized which can make distortions and artifacts in the enlarged image virtually unnoticeable to the human eye. Here are three of those techniques:
Take Smaller Steps Up To 300% Enlargement
Rather than stating a specific image size you want to enlarge to, the better technique for allowing interpolation to be more successful at predicting the outcome of the enlarged image is to enlarge by percentages until a point of distortion is reached. In general, medium to large photos can be enlarged by 200% without any noticeable change. 300% is stretching things a little bit, but can often be achieved. However, enlarging beyond 300% is probably going to produce distortion.
By taking smaller steps up to 300% enlargement, you can maintain the quality of the image, but also make it large enough to emphasize whatever it is you are attempting to highlight in the image. Reaching that balance of enhancement with minimal distortion often rests on a very thin line.
The bigger the original image, the better
Starting with a larger image, which is achieved with higher megapixel cameras and higher dpi settings makes producing a higher quality enlargement that much easier to achieve. A smaller image will show distortion and artifacts with just the slightest amount of enlargement, but a larger image can withstand a great deal more enlargement without any noticeable loss of quality.
In relation to the tip we already discussed, enhancing to 200% on a smaller image might look even worse than enhancing a larger image to 300%.
Sharpening the image
One way to overcome the distortion of an enlargement is through the use of sharpening. Essentially, you can push your enlargement right up to the very edge of distortion and then utilize an image sharpening tool in your photo editor to clean up that distortion. Image sharpening is not a miracle tool, but it can allow you a little bit more leeway when it comes to enlargement percentage.
Remember that we said that achieving the balance between enhancement and distortion rested on a thin line. Think of the sharpening tool as a means of making that thin line just a little bit wider for achieving that balance.
With the knowledge you have gained above as well as the three tips we just gave you, you can take a little bit closer look at some of the various software solutions available for enlarging images without losing quality.

If you are among the ranks of infrequent users, there are some free, user-friendly options with a shorter learning curve that do a pretty decent job of resizing.
Gimp
The freeware alternative that is most comparable to PhotoShop can be found in Gimp. Gimp will also produce enlarged images with minimum quality loss, but that quality will still fail in direct comparison to what you will get with Perfect Resize with PhotoShop. The scaling process with Gimp is about as simple as it can get, just be sure to choose Sinc (Lanczos3) as the interpolation method whenever you scale-up your photo.
Besides being open source free software, some of the upsides of Gimp include its compatibility with Windows, Mac, Linux and other various platforms, source code provision for those who know how to optimize the program, supports all popular image source formats, and has a variety of additional editing features available beyond enlargement. On the downside, the learning curve for Gimp is a lot steeper than a lot of other image editing applications and it really only utilizes basic editing when compared to PhotoShop.
When it comes to free, open-source software, Gimp is toward the top of the heap and a great option for those who are a bit more tech savvy.
Irfanview
The compact editing program, Irfanview, provides a smart way to resize and enlarge images. Enlarging includes the selection of your new image size, the viewing of a resample and the selection of apply sharpening to the photo after resizing. Irfanview also utilizes Lanczos3 interpolation to provide the best lossless result possible among free software.

On the downside, this software is not compatible with Mac operating systems, it can only enlarge photos up to 600 x 600 pixels, and the output quality leaves a little something to be desired.
Infrequent users will probably be okay using this enlarger for their limited needs, but those who do a lot more with image editing will find this program lacking a great deal.
Reshade Image Enlarger
A fully functional enlarger and image editing software program which also produces decent quality enlargements is Reshade Image Enlarger. The enlargement function of this application is very user-friendly and has plenty of customized or preset options to choose from. Though it doesn’t go a long way with its additional editing features, there are enough available to enhance and clean up enlargements for a clearer presentation.
Photo defects and image noise reduction is an upside feature of Reshade Image Enlarger, which also provides batch image enlarging and allows you to add focus to enlargements which have been blurred a bit. What it does not provide are advanced photo editing tools, truly high-quality results and it does not have Mac compatibility.
You can enlarge photos and clean them up a bit with Reshade Image Enlarger, and that’s just about it.
A Sharper Scaling
Another Windows based application, which provides improved image scaling quality, is A Sharper Scaling. This software uses an algorithm especially designed for improving the quality of the image produced through scaling. This software utilizes bicubic or bilinear interpolation to produce some of the best quality enlargements among open source, freeware, image-editing programs.
This software is streamlined to provide the very easiest and most user-friendly enlargements possible, which is certainly encouraging to novice users, but it also allows more knowledgeable users to choose from four different interpolation algorithms to achieve precision results. However, this software does not offer any preferences or options, it does not allow for bulk processing and it is not compatible outside of Windows operating systems.
You can do a bit more tweaking and fine tuning on your enlargements if you do your editing and enlargements on a Windows based PC, but you are very limited beyond that when using A Sharper Scaling software.
PIXresizer
About the easiest free open-source enlargement software available is PIXresizer. This software is so stinking simple that it almost isn’t fair. In essence, you load an image or open a file to batch process several images, you pick from the pre-set image sizes, adjust by percentage or set a custom size (with or without maintaining aspect ratio), you choose your output format and resize the image. The new image is saved to the file of your choosing and you can move on to other tasks.
This software is almost stupidly simple to use, which is great for a novice, it allows you to do single photos or batch processing, it allows you to choose or customize the image size and allows you to choose the output format (including pdf) and change formats if you like. There are a few downsides, including: not allowing any other type of image editing, depending upon the enlargement ratio, the image might become a bit distorted, its appearance is strictly utilitarian and old fashioned.
PIXresizer is one of the most reliable and simple to use image enlargement programs available, and that even includes those which you pay for.
