With this advantage, however, comes a larger file size. Unlike JPEG, they use lossless compression, which means they don’t lose as much quality when you edit them. PNG: the file format used mostly for illustrations and logos.If you edit a JPEG, though, be aware that it will lose quality due to using lossy compression. They come with a small file size-making them ideal to share-and a large color palette. JPEG: used primarily for sharing photographs online.So, before we delve into how to convert raster to vector, we’re going to look at what these file formats are. If you’re completely new to the world of file formats, then you might not have even come across the terms ‘raster’ and ‘vector’ much before. Why Do I Need to Convert Raster to Vector?.Whether you need a higher quality image for your website or are looking to use designs in CAD, we’ll show you exactly how you to convert to vector. Scan2CAD’s latest guide is aimed at complete beginners to the world of rasters and vectors. Our beginner’s guide on how to convert raster to vector will have you impressing your friends with your vast knowledge in no time at all! Don’t worry if you’re completely new to all of this. If you’re working in or around graphics, CAD or CNC, you’ll need to look towards alternative file formats: vectors. Despite their versatility, however, they’re not always a suitable format to use. If you’re sharing a picture with your friend or putting together a website, odds are that it’s a raster file. The following screenshots, however, will give you some idea of what to expect.Raster images are used worldwide by people in all kinds of industries and fields. The best way to learn what your options are is simply to experiment with the settings. You’ll probably also want to “Ungroup” the image. If you want to do further editing, click the “Expand” button. Once you are satisfied with the preview, click the “Trace” button at the bottom of the window. Ignore White: White areas won’t be filled so anything you place behind the image will show through where the white was. Strokes only will result in a line drawing. Higher values mean that more noise will be eliminated in the result.įills and Strokes: Choose to have filled areas, strokes, or both. Move right for a more realistic result.Ĭorners: Higher value means more corners. Move left for a simplified, more abstract result. Threshold: Pixels darker than the threshold are converted to black. Once you’ve settled on a preset, then you can begin to customize the result further using the following options. You can continue to experiment as long as you wish. Within a few seconds, you’ll see the preview image. If this is your first time using Image Trace, start by clicking on the various preset buttons at the top or selecting presets from the dropdown menu. This is my preferred method, not only because it gives me much greater control over the vectorization process, but also in most cases I’m going to be doing further editing of the vector file anyway.įirst, open the image in Illustrator. I found a great variety of output when uploading the same raster file to different services. If your resulting vector image is unsatisfactory, you can try a different service. Screenshots on both Mac and Windows are in the PNG format, which is accepted by all of the online services I tried. The fastest way to convert the GIF image is just to take a screenshot of it. If you want to vectorize a GIF file from the ClipArt ETC website, you’ll find that some of the online services do not accept the GIF format. You can experiment until you get the best result. Some services will give you a few choices about what size speckles to ignore or how much to smooth curves. You’ll upload your raster file and within a few seconds, you’ll be able to download a vector file. The interface for most services is very simple. Doing an internet search for “vectorizer” or “convert raster to vector” will give you many results. Due to changing URLS and advertising content, I don’t want to link directly to any of the online services. In general, you will have much less control using a free online service however. If you’re in a hurry or don’t have access to a drawing program, there are free online services you can use. The best way to convert a raster image to a vector image is to use a vector drawing program like Adobe Illustrator. They want to smooth out and simplify a detailed raster image-perhaps for use as a school logo.Ĭonverting a Raster Image into a Vector Image.They want an image they can enlarge greatly-for example they want to project it onto a cafeteria wall to trace and paint as a large mural.There can be many reasons for preferring a vector image file to a raster file, but the two most common reasons users contact me are either:
