When to Convert

Common scenarios where this conversion is useful

Use legacy clip art on the web

Old Windows clip art stored as WMF cannot display in web browsers. Convert to PNG so these graphics work in HTML pages, blog posts, and email newsletters.

Insert legacy graphics into modern presentations

Google Slides and Keynote do not support WMF. Convert to PNG to insert legacy Windows graphics into modern presentation tools on any platform.

Create thumbnails from old Windows graphics

If you have a library of WMF clip art or diagrams, convert them to PNG to create thumbnail previews that any image viewer or file manager can display.

Import into design tools

Modern design tools like Figma, Canva, and Sketch do not import WMF. Convert to PNG first, then place the rasterized graphic in your design.

Frequently Asked Questions

WMF (Windows Metafile) is a legacy vector graphics format from the early Windows era. It records drawing commands (lines, rectangles, text) rather than storing pixels. WMF files are commonly found in old Word documents, PowerPoint presentations, and Windows clip art libraries.

PNG is universally supported by every browser, operating system, and design tool. WMF only works on Windows and is not supported by modern web browsers or most macOS/Linux software. Converting to PNG makes the graphic usable everywhere.

If the original WMF has transparent regions, the PNG output will preserve them with full alpha transparency. PNG supports 8-bit alpha, which is a significant upgrade from WMF's limited binary transparency.

LibreOffice renders the WMF at a standard resolution suitable for screen viewing and web use. The exact dimensions depend on the original WMF canvas size.

Currently, files are converted one at a time. Upload each WMF file individually to get its PNG output.

No. WMF (Windows Metafile) is the older 16-bit format. EMF (Enhanced Metafile) is the improved 32-bit version with better graphics support. Both can be converted to PNG here.

Yes. ChangeThisFile is completely free. No signup, no watermarks, no limits on the number of conversions.

Yes. Text rendered as vector drawing commands in the WMF is rasterized into the PNG image. It becomes part of the image pixels and is no longer editable as text.

Yes. If you need to keep the graphic scalable, use the WMF to SVG converter instead. SVG preserves vector paths while being universally supported by modern browsers.

Most WMF to PNG conversions complete in 15 to 60 seconds. WMF files are typically small, so processing is fast.
