About Video Trimmer & Cutter
Standard desktop video editing suites (such as Adobe Premiere Pro, Final Cut, or DaVinci Resolve) are heavy software applications that take gigabytes of disk space and require steep learning curves for simple trim operations. Conversely, typical cloud-based video trimming websites force you to upload your sensitive video files to remote servers, subjecting your data to privacy breaches, long upload delays, and watermarks. Our Browser Video Trimmer uses HTML5 Canvas and the W3C `MediaRecorder` API. When you specify a start and end boundary, the video seeks to the start timestamp, renders frames sequentially through a hardware-accelerated canvas context at 30 FPS, pairs the synchronized audio stream, and records the exact time slice into a standardized WebM video container. The entire workflow occurs 100% locally on your machine with zero cloud dependencies.
Frequently Asked Questions
Can I preview only my trimmed selection before exporting?
Yes. Click the 'Preview Selection Only' button to automatically loop through your chosen start and end time boundaries.
Are my personal videos uploaded to your server?
No. Video trimming, canvas frame extraction, and recording execute strictly within your local web browser sandbox. No video bytes ever leave your device.
Does trimming keep the original audio?
Yes. The trimmer captures the video's audio track and multiplexes it into the exported video container.
What video formats can I trim?
Any video format natively supported by your web browser, including MP4 (H.264), WebM, and MOV.
