Free online MET to WEBP converter

Older OS/2 graphics and documents may contain MET metafiles that current image editors and websites cannot use directly. Converting one to WEBP creates a raster image suitable for web pages and applications that accept WEBP.

What the MET format is

In graphics, MET commonly refers to an OS/2 Presentation Manager metafile: a legacy format that stores drawing instructions rather than a finished pixel image. It is most likely to appear in files produced by older OS/2 software or in archived documents and graphics.

What the WEBP format is

WEBP is a raster image format used on websites and in software that supports it. It supports lossy and lossless compression, transparency, and animation; for a static MET graphic, conversion produces a still image. WEBP can reduce file size compared with some older image formats, but it is not supported by every legacy application.

Convert online on 101convert.com

1. Upload the MET file to the converter. You can add several files for batch conversion; the page shows the per-file size limit.
2. Before converting, set any needed options: pages, resolution, quality, image size, max width, max height, auto orient, or strip metadata.
3. Choose WEBP as the output format, start the conversion, then download the converted file.

The conversion runs on the service’s server with LibreOffice, then ImageMagick.

Convert offline with desktop software

ImageMagick is free and open-source, with command-line versions for Windows, macOS, and Linux. Install a build that includes both the MET reader and WEBP writer, then run:

magick -density 150 input.met -quality 85 output.webp

Replace the filenames as needed. The density setting controls rasterization resolution; 150 is an example value, not a requirement. The quality setting applies to lossy WEBP output. Check that your ImageMagick build lists both MET and WEBP in magick -list format; support depends on the build.

Quality and conversion limits

MET drawing instructions must be rasterized for WEBP, so the chosen resolution affects sharpness and pixel dimensions. Increase the density when the result needs to remain clear at a larger size. Lossy WEBP can introduce compression artifacts; use a higher quality value or lossless WEBP when preserving detail matters and your converter supports that mode.
