Basic information about vector graphics files and how to open vector graphic files
About vector graphics files
Vector graphics file types are typically generated by drawing or illustration programs (e.g. Adobe Illustrator, CorelDRAW) and are composed of mathematically-defined geometric shapes-lines, paths, objects and fills. Since vectors entail both magnitude and direction, vector elements thus are comprised of line segments whose length represents magnitude and whose orientation in space represents direction.
Vector graphics usually are easily modified within the application, which created them and generally are not affected detrimentally by scaling (enlarging or reducing their size) compared to raster or bitmap image file types, where image scaling reduces picture quality. Because vector elements are mathematically-defined, scaling simply requires modification of their mathematical locations.
However, vector files don't support photographic imagery well and often can have difficulties with cross-platform exchange.
The most used vector graphics formats are:SVG (Scalable Vector Graphics), AI (Adobe Illustrator Graphics), CDR (CorelDraw Vector Graphics), WMF (Windows Metafile Format) and DRW (Vector Drawing file).
You can check all Vector Graphics file formats sorted by name in our Vector graphics file type category, that you can access from the main page on the left category bar.
How to open and view vector images
Vector graphics can be usually opened and viewed by most image viewers or graphic editors. Some special and often proprietary vector graphics formats can only be opened in a special viewer or editor, but the common formats are supported by most if not all f them.
Simply check our database for the vector graphics file extension you are looking for and in the table below its description you will see a table with software, sorted by platform and actions, that is able to perform a specific action with the the the the vector graphics files, such as open, edit, print etc..
You can also click on each software to open its own web entry on our website, that often contains additional useful information about it, such as developer, website, reviews or other useful articles.
How to open unknown vector graphic file
If you want to open a vector graphics file with file extension that is not recognized by your image viewer by default, you can try the following and open the file. If the file is really in vector graphics format you will be able to open and view it. Otherwise an error will occur and tell you that the image viewer is not able to open the file.
Try to use the File → Open... action, that is available in most programs and select All files (*.*) option in the browse menu, that will show even files that are not supported the application by default. If the file is a common vector graphics file, you will open it regardless of its file extension and see it.
More information can also be found in our how to identify unknown file formats article.
Please note: Adobe discontinued support for Adobe SVG Viewer on January 1, 2009. Please read Adobe discontinued SVG Viewer for more information. If you’ve been directed to download the SVG Viewer, it’s an old message. You can open most SVG files in any modern browser. Before downloading the SVG Viewer, try opening the files in your web browser. |
Download Adobe® SVG Viewer 3 to view Scalable Vector Graphics in browsers that do not provide SVG, such as browsers from the early days of the millennium.
Adobe SVG Viewer 3.03
Version 3.03 of Adobe SVG Viewer is an update provided by Adobe to fix a potential secuirty risk on Windows® computers. In addition, the ActiveX control has been signed in order to allow users to avoid the ActiveX security warning introduced with Windows XP Security Pack 2.
Adobe SVG Viewer 3.03 addresses a potential security risk in the ActiveX control whereby a malicious web page could determine whether or not a file with a particular name exists on the user's computer. The contents of the file could not be viewed via this vulnerability, and directory listings could not be obtained. Adobe is not aware of any malicious exploit of this potential security risk, but we are grateful to Hyperdose Security for bringing this potential security risk to our attention. Adobe SVG Viewer 3.03 also includes the fixes provided in Adobe SVG Viewer 3.02.
Adobe SVG Viewer 3.02
Version 3.02 of Adobe SVG Viewer is an update provided by Adobe to fix a potential secuirty risk on Windows computers, and to fix a bug in the installer which prevented installation on some Windows XP systems.
Adobe SVG Viewer 3.02 addresses a potential security risk in libpng described by CERT vulnerability 388984. Please see the CERT vulnerability note for details. Adobe SVG Viewer 3.02 also includes the fixes provided in Adobe SVG Viewer 3.01.
Adobe SVG Viewer 3.01
Version 3.01 of Adobe SVG Viewer is an update provided by Adobe to fix potential security risks on Windows computers.
Adobe SVG Viewer 3.01 addresses one potential security risk by disabling SVG scripts if you disable ActiveScripting in Internet Explorer. This security risk only affects customers who browse the Web on Windows computers in Internet Explorer with ActiveScripting disabled. By default, ActiveScripting is enabled, so most users are not currently at risk. Because of the way that the HTML OBJECT tag is implemented in Internet Explorer, Adobe SVG Viewer 3.01 cannot determine the URL of a file embedded with the OBJECT tag. The URL is required to determine the security zone, which is required to determine the state of the ActiveScripting setting. Therefore, to fail safe against this potential security flaw Adobe SVG Viewer 3.01 always disables scripting when it determines that the SVG file is embedded using the OBJECT tag. When authoring in SVG, Adobe recommends that you not use the OBJECT tag and instead use the EMBED tag when embedding SVG in HTML pages.
Adobe SVG Viewer 3.01 also includes a fix for a potential security risk involving the JavaScript alert call when used in conjunction with JavaScript executing in another thread. It was possible for an SVG document to pop up an alert dialog while another script in the HTML document changed the location of the window to a private domain. When the original script regained control it would have been able to access private domains and potentially send protected information to a remote machine.
Adobe is not aware of any malicious exploits of these potential security risks, but we are grateful to GreyMagic Security Research for bringing these potential security risks to our attention.
