Cut Video Online: Trim MP4, MOV, MKV Instantly (Lossless)

Video editing is essentially the art of subtraction. It's about removing the boring parts to reveal the interesting parts. Whether you recorded a 30-minute gaming session and just want the 15-second winning kill, or you filmed a family event and want to cut out the part where you forgot to take the lens cap off, trimming is the most fundamental task in video creation.

Reelic's Online Video Trimmer is built for speed and precision. Unlike timeline editors which can be overwhelming, our tool focuses on one thing: selecting a Start Point and an End Point. You drag the handles, preview your cut, and export.

Crucially, we use "Lossless Cutting" technology where possible. Most editors re-encode your video, which takes time and reduces quality. Reelic attempts to slice the video file directly at the data level, meaning the quality remains 100% identical to the original and the process is near-instant.

Why Trim Videos?

Remove Dead Air: Eliminate the awkward silence at the start of a Zoom recording or the 'fumbling for the button' moment at the end of a TikTok.

Improve Retention: Social media attention spans are short. If your video doesn't get to the point in 3 seconds, people swipe. Trimming the intro is the easiest way to boost views.

Reduce File Size: Why upload a 1GB file when the part you care about is only 50MB? Trimming is the most effective form of compression.

Create Highlights: Turn a long podcast episode into ten short 'Clips' for Shorts and Reels.

Lossless Cut vs. Re-encode

Reelic is smarter than the average cutter. We analyze your file structure.

Lossless Mode (The Ideal): If you cut at a 'Keyframe' (a full picture frame), we can simply discard the unwanted data packets and save the new file without touching the pixels. This takes less than a second even for 4K video.

Precise Mode (Re-encode): If you need to cut exactly between keyframes (e.g. at 12.5 seconds), we must re-encode the video pixels to create a new keyframe. This takes slightly longer but gives you frame-perfect accuracy.

How to Trim a Video Step-by-Step

  1. Upload: Drag your long video file into the box.

  2. Set Range: Use the yellow handles on the timeline. The Left Handle is the Start. The Right Handle is the End.

  3. Fine Tune: Use the input boxes to type exact timestamps (e.g., 00:01:45) if you know exactly where the action starts.

  4. Preview: Click 'Play' to watch only the selected section. Adjust handles until it's perfect.

  5. Cut: Click Export. Download your new, lighter file.

Supported Formats

We support trimming for all major modern video containers:

MP4, MOV, Canvas, WEBM, MKV, M4V.

If you upload a weird format like AVI, we will convert it to MP4 first so you can preview it in the browser, then trim the converted file.

Privacy First

As with all Reelic tools, the video file never leaves your computer. If you are trimming sensitive bodycam footage, legal depositions, or personal family moments, you can trust that no cloud server is seeing your data. It is processed locally by your browser.
