Available in zenfmt 0.3.5
Use the same converter as a small HTTP service.
For workflows that need a shared endpoint, zenfmt serve
exposes conversion, health, and metrics from the same executable. Open
mode stays on loopback by default. Secure mode adds users, API keys, an
audit log, and a small administration interface.
zenfmt serve
curl -s -T report.docx "http://127.0.0.1:8998/api/v1/convert?to=markdown"
zenfmt serve --secure --data-dir ./zenfmt-dataThe release is intended to remain modest in its requirements. It does not bundle Java, Python, OCR, VLM, or model assets. Read the server guide or choose a native archive.

A small reference benchmark
The conversion benchmark
The full release benchmark is incomplete. Earlier reference run. Ratios divide the comparison tool by zenfmt, so a value above 1.0 means the comparison used more of that measure on shared files.
Native CLI
Geometric means over the 14 files converted by zenfmt and AnyDoc.
Long-running server, measured separately
Warm HTTP conversion against Apache Tika Server on the same host and corpus. These values are not mixed into the native CLI ratios.
