About

Wondershare UniConverter 18 is a desktop media suite for Windows and Mac that handles video conversion, compression, enhancement, editing, and screen recording in a single application. It targets a common frustration for anyone working with video: files arrive in the wrong format, are too large to upload, look or sound poor, and converting them repeatedly wastes time. The software supports more than 1,000 media formats, including 4K and 8K HDR material, and Wondershare states it performs lossless conversion at up to 130× speed.

The application is developed by Wondershare, a company with roughly twenty years of history in consumer media software. Version 18 adds an AI Media Agent that interprets a plain-language goal, such as a target platform or file size limit, and plans the conversion steps accordingly. Batch processing, watch folders with saved presets, and CPU control let users automate repetitive jobs while AI features handle enhancement, subtitles, transcription, and audio cleanup.

Key Features

AI Media Agent: Users describe an intended use, platform, or delivery limit, and the agent plans the conversion steps and adapts settings file by file.
Format conversion with audio pass-through: Converts between 1,000+ formats while keeping original audio streams in their codec and preserving subtitles, chapters, metadata, and multi-track structure.
Target-size compression: An upgraded compression model predicts final file size more accurately and improves visual quality at the same ratio, which reduces repeated exports.
AI video and image enhancement: Features include AI Auto Fix for image repair, Face Enhancement-Ultra, and Photo Straightener for correcting photographed scans.
Motion-tracking blur and smart erase: Users can blur details that follow moving subjects and remove unwanted objects or distractions from footage.
Batch processing, Watch Folder, and CPU control: A folder can trigger an automated workflow with presets, reducing manual repetition on large jobs.
AI audio and text tools: Includes Speech to Text, Text to Speech, a Subtitle Editor, and a Vocal Remover for transcription, narration, and audio separation work.
