What Is Rasterization?
Rasterization is a process in which a vector format is taken and converted to a raster image. A raster image is a series of pixels, dots, lines that, when combined and displayed together, form an image. Rasterization is a common way to render 3D models, it is comparatively a faster way to render 3D models than other techniques. A raster image can be printed or can be saved in a bitmap file. An image needs to be converted to a raster image to be able to edit all the layers of a vector image such as text, masks, etc. Rasterizing will allow us to use all the painting tools, filters, and every graphic tool on a vector image. This brings us to the next question. Why do we require rasterizing our image?
Why Do We Require Rasterizing on Illustrator?
Rasterization of images is required so that we can edit our images with various sets of editing tools, painting tools, filters, and many graphic tools. As we all know, rasterizing is altering vector images into pixels, dots, lines. Vector images are made of a few mathematical formulas, so converting this into a raster graphic and editing would help create an image that would have images with clear and crisp edges, and these images can be scaled up easily. But what is the need of rasterizing the image on Adobe Illustrator when there are a lot more software programs which serve the same purpose?
Raster Graphics in Illustrator
Adobe Illustrator is software that allows us, to edit and create 3D models, typography, etc. It is software for vector images, which means it layers texts, etc. to create quality images. Adobe Illustrator can convert a vector image into a raster image, this will allow us to use various sets of editing tools within the Adobe Illustrator for our image, so we can create quality content for ourselves. These raster images can be printed or stored in a bitmap file. Illustrator can also help in converting raster images into vector images.
Though, there are many other software programs for rasterizing an image. Adobe Illustrator has a wider variety of options when compared to other software programs. Adobe Illustrator has a very friendly user interface, and it can create manageable-sized files. It can create graphics and website graphics. It works on every OS and is completely scalable. Rasterizing images on Adobe Illustrator is done, so vector images can be rasterized and be opened into programs that do not support vector graphics. Now, let’s see the step-by-step procedure on how to rasterize an image on Adobe Illustrator.
How to Rasterize in Illustrator
- Open Adobe Illustrator and upload the desired image you want to rasterize.
- After the image is uploaded, choose the object you want to rasterize If you want to rasterize more than one object in the image, then press the “Control (Ctrl)” button as you click on the object you want to rasterize.
- Next you would have to go to the “object menu” after selecting all the objects you want to rasterize.
- In the object menu, you find a button called “Rasterize” click on this button
- After the “Rasterize menu” opens, you can choose what colors you want to use such as CMYK (Cyan, Magenta, Yellow, Black) or RGB (Red, Green, Blue). You can choose these according to your preference.
- Select the resolution for your image. The resolution decides on the pixels per inch on the image
- Select the background. If you want Illustrator to fill in the background on the objects that need to be selected, then go with a “white” background. On the other hand one can disable the vector image from the background by choosing a “transparent” background
- If you want your lines to be clean and crisp, then put the “anti-aliasing” option on none. As rasterizing would make the lines on the image blurry.
- Click on “OK” to rasterize your image permanently.
This is the procedure for how to rasterize in Illustrator permanently, but what if you want to only have a raster effect. There is a procedure for that too.
Here Is the Step-by-step Procedure.
- After selecting the objects you want to rasterize. Select the “Effects” button on the toolbar.
- Choose the “Rasterize” option on the effects menu, and the “Rasterize menu” opens.
- Select all the preferred options on the “Rasterized menu” such as colors, Resolution Etc.
- Find the “appearance panel” and click on the “rasterize” option to make changes or delete the effects
- Go to the “File” option on the menu and click on “Save” or “Save As” to create a Raster Effect.
How to Unrasterize?
Now that we know how to rasterize in Illustrator, Let’s see how to Unrasterize. Rasterizing is something you can not undo unless you save it as a copy. If you did not save the image yet, you can use “Ctrl + Z” to undo whatever you have done, but this is only possible in a certain amount of steps, and once you go too far the undo option will not be of any help. There is only one solution for this. That is Image Trace. Image Trace is used to convert raster images to vector images. With Image tracing, you can create a pencil drawing into a vector image. Image Trace offers us specific presents through which we can get an image we want quickly. To unrasterize your image
- First, upload the image to Illustrator
- Then choose the objects you want to trace and select “Image Trace” on the control panel.
- After this, select the “Make” option, this will make Illustrator trace by default.
How to Add Specific Colors to the Image?
In Illustrator, the image is converted to a black and white image when it is traced by default. If you want to add specific colors to your image, then you will have to go to the “Image Trace” menu and select a present according to your preference. You can choose
- “Auto color” and will create a specific image from the photo
- The next option is “High Color” which creates a realistic image
- “Low Color” will create a realistic image, but this image will not be as bright as a high color image
- “Grayscale” this option traces the image in gray color
- The “Black and White” option creates a black and white image
- The “Outline” option creates black outlines of the image
If you want to trace the image with a specific color or a specific present, you can select the “Advanced” drop-down menu and choose the specific options you desire for your image. But remember, the vector’s quality, created after unrasterizing will not be as high as it was before rasterizing. Most of the changes you will see after unrasterizing will not be editable. The better option is to make a duplicate before rasterizing on Illustrator or save the rasterized image as a copy, so you don’t have to lose the quality of the vector image you had before.

Difference Between Raster Graphics and Vector Graphics
A raster graphic is made of pixels, dots, lines, etc. they use color and tone to produce an image. A vector graphic is made of a mathematical formula. Vector files are smaller than raster files because they have lesser data than a raster file. Raster graphics are good for photos and vector graphics are good for designing logos, business cards, etc. Vector images are scalable and not device-dependent, whereas raster images are device-dependent and are very large files. The file formats for raster images are: .JPG, .BMP, .GIF, .PNG, .TIFF.
The file formats for the Vectors are EPS, SVG, AI. The software is compatible with vector in Adobe Illustrator. The software compatible with raster is Adobe Photoshop.
Raster Illustrator, i.e, how to rasterize in Illustrator can be done easily with the steps we have given above. It can also be undone, which we what we referred to as “Unrasterizing”. But always remember to save a copy or to duplicate the image before rasterizing, as once you finish rasterizing you can not go back. Also, steps for downloading the Adobe Illustrator have been given above, compare and choose your plan. The is the step that has to precede rasterize on Illustrator.
You can opt to pay either yearly or monthly, choose this option according to preference. To sum up, about vector and raster, both these graphics are unique and have their pros and cons. We can use either of them depending on what purpose we are using them for, if it’s for photography choose Raster graphics. If it’s for logos and posters etc. then go with vector graphics. Both the graphic formats have their dedicated editing software: Adobe Photoshop for raster graphics and Adobe Illustrator for vector graphics.
Frequently Asked Questions(FAQs)
They are both used for different purposes and have dedicated editing software programs, so they are both unique and great for their purpose.
No, you cannot download it for free, but you can try a 30-day free trial. Just go to their official website, select a plan and click on try 30-day free trial and download it.
Yes, Undoing rasterization is possible, but the image will not be as sharp as it was before. We have provided the steps to undo this above.
Photoshop is based on raster graphics and uses pixels to create images. It was created to edit photos and other raster-based images. Illustrator is based on vector graphics and works on points that create clean and crisp lines. They are good for designing posters, cards, website graphics, and social media graphics, etc.
