Where the timing appears
After Convert All finishes, the batch file list shows a compact duration next to each successful file. Typical Office and HTML documents still land in about 2-5 seconds; image-heavy PDFs and larger spreadsheets often take longer, and the badge makes that difference visible immediately.
How teams use it as a gate
Operators can re-check only the slow outliers, confirm the Markdown outline still looks intentional, then download the ZIP. Timing is a signal, not a quality score: a fast file can still have a flat heading tree, so keep using the outline preview together with the new duration badge.
