Overview
Audio & Video tools on SmarTool Palace are grouped around one purpose: helping users trim, convert, preview, and record media with browser-supported formats. The category includes Audio Extractor, Audio Player, Audio Cutter, Video Cutter, Audio Converter, Screen Recorder, and additional focused utilities, with each page pairing the working tool with practical notes about inputs, checks, and limitations.
Choose the utility that matches the final output you need first, then check whether the page asks for a file, value, URL, date, location, or live lookup. If a task affects money, health, legal deadlines, publishing quality, or official documents, use the result as a reviewed estimate and confirm it with the relevant professional, authority, or source.
Available formats and processing speed depend on browser support, file size, codec, and device performance.
