Before jumping into that topic, it is important to know how digital images are formed in the first place. There are basically two different techniques of creating a typical digital image.
Raster (Bitmap): A Bitmap (Raster) consists of a grid of individual pixels, each defined by a specific color in the form of binary bits (hence the name). Popular image formats like JPEG, GIF and PNG save images as bitmap graphics.
Vector: In vector graphics, a set of mathematical expressions is used to define line segments, curves and other geometrical shapes that combine together to form a complete image. Drawings made in vector-based applications like Adobe Illustrator or Corel Draw are usually in vector graphics.

PhotoSize lets you upload and export to some of the most popular image formats like JPEG, TIFF, PNG, PSD or GIF. Steps To Resize Images On Mac. There can be many ways to resize images on Mac without losing quality. But here we are covering four major ways which are not very technical. So, let us begin with these basic methods. Resizing in Preview: When you double-click on an image on your Mac, Preview is the application that opens it up by default.
As vector graphics are mathematical representations, they can be resized or enlarged to any extent without any loss of quality (distortion-free scaling). However once the scaling is done, you need to export it to bitmap form in order to use it. Nowadays though, several vector formats, such as SVG, are directly supported in web browsers.

Why bitmap images get blurred on enlargement?
The answer to this might be best explained with the Egyptian Pyramid analogy. The Pyramids of Egypt are ancient pyramid shaped structures built using huge stone blocks. When we see the Pyramids from a distance, they seem to be smooth pyramidal structures with straight edges. But if we look closer, we can start noticing significant roughness in the structure. Up close, you can clearly differentiate the stone blocks making up the edges of the Pyramids, which are, in fact, not straight at all.
On a similar note, when you gradually zoom into a bitmap image using an image viewer, at first the image may appear to be grainy. On further zooming, the edges in the picture become pixellated. At the highest level of zoom, you can clearly distinguish individual pixels based on their color, and the overall appearance of the image becomes blurred.
Usually, you can zoom an image up to 100 percent without distortion. In such cases, one pixel of the image corresponds to less than (or equal to) one pixel of the display screen.
But when the image is enlarged beyond 100 percent, one pixel of the image is represented by more than one pixel on the display screen. That’s when you begin to distinguish individual pixels in the image (the grains). On zooming more, the pixels become more prominent (especially at the edges) and you can actually see the image comprising of square boxes of different colors. Thus, the overall image gets blurrier with more zoom.
Enlarge images without losing quality (Lossless)
Vector Graphics is the only form of image that can preserve its quality while enlarging it. If you want to enlarge bitmap images without losing quality, one way of doing so is to generate the vector form, enlarge, and then export them in bitmaps.
The process of converting bitmap images into vector is known as tracing. In the following section, we have used an application called Vector Magic for lossless enlargement of images.
Resize image without losing quality – software
Vector Magic is a bitmap to vector conversion tool that works well with logos, clipart and other forms of simple artwork. it is available as an online tool as well as a desktop application. Supported bitmap formats include JPEG, GIF, PNG, BMP, TIFF, PSD, etc. while supported vector formats include EPS, SVG, PDF, AI, DXF, EMF, etc.
The desktop application provides offline access to all Vector Magic features on your Mac or PC. The software includes an unlimited trial version, which has all the features of the full version enabled (including full preview) except for the Save feature. To activate the Save feature, you need to purchase the software ($295 per license).
The following table gives you a complete feature comparison between Online and the Desktop Editions of Vector Magic.

The online version of Vector Magic allows you to upload bitmap images and convert them to vector form using automatic settings or manual settings. You can preview the result of the conversion and adjust the individual settings in the online editor if you like. But for downloading the vector graphics, you need a paid subscription.
In order to download vectorized images online, you need to either subscribe to Vector Magic Unlimited ($7.95 per month) or pay 1 token per download. A free sign up gives you two free tokens, which means you can download a maximum of two images for free. You can buy token packs containing 5, 10 or 20 tokens.
Free online photo enlarger
Besides Vector Magic, there are some free online tools available that allow you to vectorize bitmap images and download them. Some of these free online conversion tools include Autotracer, Vectorization, RapidResizer, etc.

Advantages of Vector Magic
Even though there are a few other free alternatives available for bitmap to vector image conversion, for professional use, it is recommended to go for the paid version of Vector Magic. Here is why you should prefer the paid solution over free ones.

Better accuracy: Vector Magic usually produces vectors that more closely resemble the input bitmap image, compared to free vector tracing applications.
Cleaner output: Usually, vector converted image results are affected by factors such as noise. Vector Magic results are usually cleaner, while still extracting more detail from the bitmap original.
Easier to use: Free bitmap tracing tools usually have a lot of settings that often confuse users. With Vector Magic, the automatically selected settings usually give the best results. If you’re not happy with it, there’s even an “Improve Result” feature to help you tweak the result.
2How to Resize Image without Losing Quality?When you resize the image, you may have to compromise its quality and get it a little noisy, pixilated and blurry. This is so because when you shrink your photograph pixels decrease and when you enlarge your pictures pixels will also increase. You can use three most popular applications to avoid such conditions – Photoshop, Vector Magic and ReShade. They can resize both photographs and graphic images without losing their quality. When it comes to adjust size, you can also shorten the image without compromising its sharpness. In most cases, it is important to maintain the quality when it comes to resize the original image. Resizing image is not a big deal if it is of good quality. In order to resize the pictures without losing their quality, here are some steps.
Resizing Image Using Photoshop
- Launch Photoshop CS and open your desired image.
- On the ‘File’ menu click ‘Image’ option and click ‘Image Size’ to open a new menu.
- Choose the option ‘Resample Image’ and then go with ‘Bicubic Smoother’ to enlage an image or ‘Bicubic Sharper’ to shrink your image from dropdown menu of ‘Resample Image’.
- Enter your desired dimensions in ‘Height’ and ‘Width’ fields and hit ‘Ok’ button.
Resizing Image Using Vector Magic
- Visit the webpage of Vector Magic and click the orange button of ‘Upload Image to Trace’. It will open a dialog box to upload file.
- Get into the location where you have stored your desired picture, highlight the file you like to resize and “Open” it. Wait for the file to upload.
- In the right pane, choose the image quality you want on ‘Desired Quality’ button. Select your desired color palette and download the resized image by clicking ‘Download Result’.
- Specify the location and file name and save the result to your PC.
Resizing Image Using ReShade
- Open your browser and visit the website of ReShade. You can upload your desired image either from the web directly or from your computer. Just give image URL or desired path of the image.
- Navigate to your desired location by clicking ‘Browse’ button to find the picture to resize. Click ‘Open’ button and ‘Submit’ the image.
- On left pane, choose the image size you desire from dropdown box. Next to ‘Stretch’, have a check mark in order to stretch the width and height of image to fit to the new size.
- Besides ‘Denoise’ put a check mark if image is quite grainy or of bad quality.
- If you have drawing, then check the ‘Smooth’ option in order to smoothen the rough edges in the picture.
- Click the button ‘Resize It’ and program will start resizing the image.
- When done, have a right click on the resized image and specify the location and desired file name by clicking the ‘Save Image As’ button. And then click on ‘Save’ button.
