Ms to WebP Converter
Processing entirely on your device — large files may take a moment.
roff ms Macros and WebP Image exist for different jobs: The ms macros are the other roff formatting package (alongside man) — Bell Labs' classic typesetting layer used for troff papers and Unix documentation since the 1970s. WebP is the go-to format for fast websites: smaller files mean quicker pages, lower bandwidth and better SEO scores.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the Ms format
The ms macros are the other great roff package: Bell Labs' general-purpose typesetting layer that produced papers, memos and books on Unix since the 1970s. Where man pages have one narrow shape, ms gives you .TL titles, .NH numbered headings, .DS display blocks — a full letterpress-grade document system in a few dozen macros.
ms remains the shortest path from plain text to a classically typeset PDF via groff. Generating ms from Markdown sources with Pandoc lets modern writing flow into that pipeline: the content is authored today, the typography comes from fifty years of Unix tradition.

About the WebP format
WebP is Google's image format, released in 2010 and built on the VP8 video codec. In lossy mode it typically produces files 25–35% smaller than JPG at the same visual quality, and it also has a true lossless mode that beats PNG. Crucially, one format covers what used to require two: lossy photos with transparency, and even animation, all in a single container.
Browser support is no longer the barrier it once was: Safari added WebP in iOS 14 (2020), and every modern browser now decodes it. The remaining friction is with older desktop software and a hard dimension limit of 16383×16383 pixels, which rules out very large panoramas and print masters.
+Strengths
- ✓25–35% smaller than JPG at equal visual quality
- ✓Transparency and animation built into the same format
- ✓Supported by every current browser and most CDNs
- ✓Has a genuine lossless mode that out-compresses PNG
!Limitations
- −Hard limit of 16383×16383 pixels per image
- −Older photo apps and OS image viewers may not open it
- −Encoding is more CPU-intensive than JPG
Why convert Ms to WebP?
Converting makes sense where the strengths of WebP meet what Ms cannot give you. 25–35% smaller than JPG at equal visual quality Meanwhile Niche outside academic/Unix circles One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this Ms to WebP converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will converting Ms to WebP reduce quality?
WebP uses lossy compression, so a small amount of recompression is unavoidable. The quality slider lets you choose between maximum fidelity and smallest file size — the default is visually indistinguishable for photos.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your Ms files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to WebP?
Transparency is kept whenever WebP actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
