Audio & video tools
Inspect, trim, amplify, capture, and speak media with browser capabilities. Audio and video utilities range from instant waveform trimming and metadata inspection to local WebAssembly container conversion, track muting, frame capture, and multi-voice neural speech synthesis.
Choose the right tool
Use lightweight Web Audio utilities when you need fast lossless WAV trimming, volume adjustment, speed changes, or reverse effects, and open the FFmpeg-powered converters when you need to transcode MP4, WebM, MKV, MOV, GIF, or MP3 containers. Check file duration and codec details first whenever a recording fails to play in a target editor.
A reliable workflow
Inspect the source container first, trim unwanted lead-in or tail silence so you only process the section you need, crop or scale the frame dimensions once, and listen to both the opening and closing seconds of the exported file to confirm clean sync and levels.
Privacy and limits
Recordings stay on your device in local memory. Microphone transcription depends on your browser vendor speech engine, while Studio voice generation downloads an open-weight model once and synthesizes audio locally on your CPU.

How this hub is maintained
Every page links back here and to closely related tools, so visitors can move through a complete task rather than returning to search after every step. ToolkitPoint keeps local tools separate from live server checks, labels download formats, and lists each tool's limitations on its own page.
Start with a disposable sample whenever an action changes a file. A successful status message means the browser completed the requested operation; it does not replace opening the download and checking the result in the software or workflow where it will be used.
