Security-first server-side conversions (ffmpeg/exiftool if installed). Upload limit: 25MB. Output files are stored under /tools/_data/outputs and served only via the download link.
Deployment tips:
Install binaries: ffmpeg and/or exiftool for best results.
Run PHP-FPM/Apache under a restricted user (www-data) and keep disable_functions hardened.
Keep /tools/_data non-browsable (a deny rule is included).

If ffprobe is installed, you’ll also see stream/container details here after conversions.
