Free Video Trimmer

Our video trimmer uses FFmpeg compiled to WebAssembly to cut and extract segments from your video files directly inside your web browser. Unlike server-based trimming tools, your video never gets uploaded anywhere. The entire process happens locally on your device, making it completely safe for personal, confidential, or sensitive video content. Whether you are trimming a legal deposition, a medical recording, or a personal home video, your privacy is fully protected.

The trimmer operates in stream copy mode (-c copy), which means it extracts the selected segment without re-encoding the video or audio data. This has two major advantages: first, the trimming process is nearly instant because no computationally expensive encoding is required. Second, the output quality is identical to the original because the video and audio bitstreams are copied byte-for-byte. There is zero quality loss, zero generation loss, and no compression artifacts introduced by the trimming process.

To use the trimmer, simply specify a start time and end time in HH:MM:SS format. The tool will extract everything between those two points and discard the rest. This is perfect for removing unwanted intros or outros, extracting a specific scene from a longer recording, cutting a clip to meet social media duration limits, or isolating a key moment from a meeting or presentation recording. The trimmed output maintains the same format, resolution, and encoding as the original file.

Supported File Types

The video trimmer supports all major video formats: MP4 (MPEG-4 Part 14),MOV (Apple QuickTime), AVI (Audio Video Interleave),MKV (Matroska Video), and WebM (VP8/VP9). The output file retains the same container format as the input, so trimming an MP4 produces an MP4, trimming a MOV produces a MOV, and so on. All embedded audio tracks, subtitle tracks, and metadata are preserved in the trimmed output.

Why Browser-Based Trimming Is Safer

When you upload a video to a traditional online trimming service, your file travels across the internet to a remote server. It may be stored temporarily — or permanently — on infrastructure you have no control over. Data breaches, employee access, and unclear data retention policies all create risk. Our tool eliminates these concerns by design. The video data exists only in your browser's memory while the tool is running. When you close the tab, the data is gone. No accounts are needed, no cookies track your activity, and no server ever sees your file. This approach is trusted by professionals in regulated industries including legal, healthcare, and financial services who need to process video files without compromising data security or compliance requirements.
