We have checked the project site of FFmpeg Subtitle Tools 153 times since 15 Sept 2026, and the site answered every time. The site's visible text has not changed since we started watching.

What it does

These FFmpeg builds add subtitle conversions that stock FFmpeg lacked, including a PGS encoder and text-to-bitmap and bitmap-to-text paths via OCR. Styled ASS/SSA animation can be preserved when converting to Blu-ray PGS. Ready-to-use binaries built on FFmpeg 9.0.1 are offered as a drop-in replacement under LGPL 2.1.

Evidence

Each bar is one request to the project's own site

This one is installed and run on your own machine, so what we re-check is the project’s site — whether it is still published and still reachable. We cannot tell you from here that the tool itself runs.
