VidStudio

VidStudio is a powerful, privacy-first video editing and processing toolkit that runs entirely in your browser using FFmpeg WebAssembly. All video processing happens locally on your device — files never leave your machine, eliminating upload wait times and privacy concerns. It supports a wide range of tools from resizing and trimming to audio extraction, subtitle burning, and watermarking, all accessible without any installation.

• Resize & Scale — Resize videos for YouTube, TikTok, Instagram, LinkedIn, Facebook, Pinterest, and more with letterbox or crop options.
• Trim & Cut — Remove sections, trim clips, and extract specific segments with frame-accurate precision.
• Compress — Reduce file size using smart compression with target size options or quality presets; includes platform-specific presets for Discord, WhatsApp, Slack, Twitter, and more.
• Drop Zone (Batch Convert) — Batch convert videos to a consistent MP4 format with professional encoding defaults.
• Audio Processing — Extract audio from video, convert formats, mix tracks, and apply audio effects; supports MP4 to MP3, WAV, AAC, M4A, FLAC, and more.
• Thumbnails — Extract frames, generate storyboards, animated previews, and video sprites.
• Watermark — Add image or text watermarks with control over positioning, transparency, timing, and movement effects.
