Video Trimmer
Trim videos online: set start and end, cut losslessly or re-encode frame-accurately – without uploading
Trimming runs entirely locally in your browser (ffmpeg.wasm) – the video never leaves your device.
Secure Browser-Based Video Trimming
Our video trimmer allows you to cut clips directly in your web browser without ever uploading your files to a remote server. By utilizing ffmpeg.wasm technology, all processing happens locally on your device. This ensures that your private videos remain private and secure at all times. You can quickly trim footage for social media or personal use while maintaining full control over your data, as the video file never leaves your local environment during the trimming process.
Choose Between Speed and Precision
You can choose between two distinct methods for cutting your video content based on your specific needs. The lossless option is extremely fast because it cuts at the nearest keyframe, though this may result in a slight offset of one or two seconds. Alternatively, the frame-accurate mode re-encodes the video to ensure the cut happens exactly where you specify. This provides perfect precision for professional edits while the lossless mode is ideal for quick adjustments where minor timing differences do not matter.
Frequently asked questions
Is my video uploaded to a server when I trim it?
No, your video is never uploaded to any server. The trimming process happens entirely within your web browser using local processing technology. This means your files stay on your device at all times, ensuring maximum privacy and security while you prepare your clips for various uses.
What is the difference between lossless and frame-accurate cutting?
Lossless trimming is very fast because it cuts at the nearest keyframe, but it may be off by one or two seconds. Frame-accurate cutting uses re-encoding to ensure the cut happens exactly at your specified timestamp, providing higher precision for those who need an exact start and end point.
Do I need to install software to use the video trimmer?
No, you do not need to install any additional software or plugins. The tool works directly in your web browser using advanced technologies. Simply select your file, set your start and end points, and trim the video instantly without ever leaving the website.
