Upload a VSSX file and the service will create a PDF representation of the Visio diagram, then rasterize pages as PNG images. Multi-page files are returned as a ZIP archive with separate images.
VSSX is a document file format. Inettools converters use it for uploading, previewing and converting documents between supported office and text formats.
PNG is a raster image format developed by PNG Development Group. The name PNG is an abbreviation for Portable Network Graphic. This image format is used primarily on the Internet for posting on web pages, since PNG files use Deflate compression without losing quality. The development of this format was undertaken in order to replace the GIF format, to which there were many complaints. PNG's image quality and specifications were much better, but unlike GIF, it does not support animation and uses the CMYK palette.
This converter shows the accepted source formats and the result format.
A damaged file or a non-standard codec can still fail even when the extension is supported.
