Trim video files by setting custom start and end timestamps directly in your browser. The online video trimmer uses FFmpeg-WASM for frame-accurate cuts with a lossless option that avoids re-encoding, preserving original quality for fast, private editing.
Online Video Trimmer — Frame-Accurate Browser-Based Cutting
Cutting video to the exact moment you need has never been easier with this browser-based video trimmer. Whether you want to remove unwanted footage from the beginning or end of a clip, isolate the perfect moment for a social media post, or extract a specific scene from a longer recording, the trimmer delivers frame-accurate results without any software download.
The tool is built on FFmpeg-WASM, which runs the industry-standard FFmpeg video processing library entirely inside your browser. When you select start and end timestamps, the trimmer can perform a lossless cut — meaning no re-encoding takes place and the original codec, resolution, and bitrate are preserved exactly. Lossless trimming is nearly instant even for large video files because the CPU does not need to decode and re-encode every frame.
For cases where re-encoding is required (such as trimming mid-GOP or changing format), full FFmpeg encoding is applied with configurable quality settings. The tool supports MP4, WebM, MOV, and other common video formats. Because all processing happens locally, your video content remains fully private — perfect for trimming confidential meetings, personal footage, or client videos.
Clipping Social Media Content
Trim the best 15–60 seconds from a longer video for Instagram Reels, TikTok, YouTube Shorts, or Twitter posts without re-uploading to a third-party editor.
Removing Intro and Outro Footage
Quickly cut unwanted lead-in and lead-out footage from screen recordings, webinar clips, or interview videos before sharing or hosting.
Extracting a Specific Scene
Isolate a precise segment from a film, tutorial, or presentation using exact timestamp input, ideal for motion analysis or highlight reels.

Download Trimmed Video
Click Trim and download the output file in seconds. The trimmed video retains the original resolution, frame rate, and audio track unless you opt to change them.
Frame-Accurate Trimming
Specify timestamps down to individual frames for precise cuts, ideal for removing unwanted content at the exact moment it begins or ends.
Lossless Cut (No Re-encoding)
Trim at keyframe boundaries without re-encoding to preserve original video quality and complete the cut in a fraction of the time of a full encode.
Multiple Format Support
Trim MP4, WebM, MOV, MKV, and AVI files. The lossless mode keeps the source container and codec; re-encode mode allows changing the output format.
Private In-Browser Processing
FFmpeg-WASM runs the trim operation entirely on your device. No video data is ever uploaded, making this trimmer safe for private or sensitive recordings.
