Free online ZMF to WEBP converter

Zoner Draw files may need conversion when a website, browser workflow, or image editor accepts WEBP but not ZMF. Converting also rasterizes the drawing into an image that is easier to share and publish.

What the ZMF format is

ZMF is the native graphics-document format used by Zoner Draw, a Windows vector-graphics application. ZMF files can contain editable drawing elements and may also include text or embedded images; you may encounter them when receiving an older Zoner Draw project or opening an archive of design files.

What the WEBP format is

WEBP is a web image format that supports lossy and lossless compression, transparency, and animation. It is useful for web pages and other workflows that accept raster images; unlike a ZMF drawing, a WEBP image is not an editable vector document. Lossy compression can reduce file size, while lossless output preserves the rasterized pixels.

How to convert ZMF to WEBP

Online on 101convert.com

1. Upload the ZMF file on the converter page. Several files can be added for batch conversion; the per-file size limit is shown on the page.
2. Before converting, set any needed options: pages, resolution, quality, image size, max width, max height, auto orient, or strip metadata.
3. Start the conversion and download the resulting WEBP file or files. The conversion runs on the site’s server with LibreOffice, then ImageMagick.

Offline with desktop software

For a free, local workflow, open the ZMF in LibreOffice Draw if its ZMF import filter is available in your installation. Use File → Export, choose PNG, and export the page at the resolution you need. Then use ImageMagick, available for Windows, macOS, and Linux, to encode the PNG as WEBP:

magick input.png -quality 85 output.webp

Change 85 to adjust lossy quality; use a value of 100 for the highest lossy quality, or use -define webp:lossless=true for lossless encoding. If LibreOffice cannot open the file, use Zoner Draw on Windows to open the ZMF and export the page as PNG, then run the ImageMagick command above.

Quality and compatibility

Conversion turns vector content into pixels, so choose the output resolution based on its intended display or print size; enlarging the WEBP later can make edges look soft. Check text, transparency, and page layout in the exported image, particularly when the original uses fonts or effects that may render differently. Keep the ZMF if you need to edit the original drawing.
