Below, we break down what a raster graphic file is and share a top raster graphics software list with nine programs to consider for your needs.
What is a raster graphic file?
A raster graphic file, commonly referred to as a bitmap image, is essentially a collection or grid of tiny pixels that make up a complete image. Each pixel (or square) has a specific hue or shade. It’s generally considered unimportant by itself — but together, the pixels make up a complete image.
A raster graphic file is mostly used to alter non-line images, like digitized photos, scanned art, or detailed illustrations or graphics. That’s because these types of images consist of gradations, undefined line work, and complexities — and being able to modify pixel by pixel can help create a flawless image.
This is actually why raster graphic files can be perfect for your product photography needs, as many raster graphic programs include features and capabilities that can help you edit product photos down to the fine details — like tones, hues, and blends.
Raster vs. vector image
While raster graphic files use square pixels, vector images are dictated by mathematical formulas to create paths, curves, circles, and more. Vector images are also more flexible to use, as they're scalable, not dependent on resolution, and smaller in size.
Typically, vector images are best used for design and illustration work — think logos, designs for promotional products, and other large-scale illustrations. That being said, you should never use vector images for product photography since raster graphics are the go-to for photo editing — but that's not to say vectors can't be helpful to your business.
For example, vector images are perfect for creating business logos and any other promotional materials — as the paths help create crisp details that can be sized up or down to fit any need you may have.
Advantages and disadvantages of raster graphics
When it comes to creating a detailed image, raster graphics are your friend. Since you can change every single pixel, it helps you create an image with a wide range of colors and complexities. Plus, raster graphic files are compatible with most photo editing programs.
Since raster graphic files are made up of tiny pixels, they're difficult to enlarge without distortion. Additionally, the more pixels a raster graphic file has, the more space you’ll need to store the image. This can become problematic when it comes to storage limitations on both your own devices and the websites you're uploading the images to. Here’s a rule of thumb: Reduce your file size down to 72 PPI (pixels per inch) for online images.
Best raster graphics software list
Whether you’re a beginner or expert and have a budget or little to spend, this raster graphics software list has something for everyone.
At a glance
Available for both free and an affordable price, Artweaver is a realistic painting tool — not just for creating original artwork, but a software you can use to turn images into pieces of art. It’s also easily accessible for both first-time and advanced users, thanks to its easy-to-use interface, customizability, and support for a broad range of tools, presets, and more. Artweaver even has brush types that mimic famous painters like Van Gogh, and has a similar interface to the widely known Photoshop.
While the free version has many of the basics, Artweaver Plus also includes more enhanced tools, extended support for PSD files, support for pen tablets, additional brush types and methods, and more. Artweaver Plus is available to download for a limited time test version.

How it compares
Artweaver isn’t like many of the raster graphic software programs on our list, as it’s more of a painting tool than a program you’d use to simply adjust a photo. But if you’re finding yourself creating raster graphics of this type, Artweaver comes at a great price point — or simply free — for a user with any level of expertise.
Another digital painting software, Corel Painter stands out thanks to its vast amount of brushes and customization options — in addition to the overall advanced interface and tools it offers creatives. Perfect for use with a stylus, Corel Painter helps save time with a vast amount of options.
