How to open a .svg file
You can open it with: Browsers, Inkscape, Illustrator. If it does not open, check that the file is not damaged and that you have downloaded it fully; also confirm that the extension was not renamed by mistake.
Quick tips
Never rename a file just to change its extension, because that does not convert the data inside. Use a proper converter or the Save As / Export option. Keep a backup copy of important image files before editing them.
