What is video trimming
Video trimming means keeping only the part of the clip that matters and cutting away the rest. It is the simplest kind of timeline edit, and it is different from cropping because cropping changes the visible frame area while trimming changes the time range. If your source video already looks fine but starts too early, ends too late, or contains a dull section in the middle, a video trimmer is usually the fastest fix.
- Remove intros and endingsCut away countdowns, dead air, screen recording setup time, or long fade-outs so viewers reach the useful content sooner.
- Keep the useful middle sectionSave only the highlight moment, explanation segment, demo section, or approved take instead of sharing the full raw recording.
- Stay lightweight and practicalThis page is built for common trimming work, not for multi-track editing, transitions, or professional non-linear editing timelines.
Core features
Everything this first release needs to solve the most common video cutting jobs well
Simple start and end inputs
Enter the exact start time and end time you want to keep. The interface avoids complicated drag timelines so the tool stays predictable and easy to understand.
Local browser processing
The trim job runs on your device with FFmpeg.wasm, so private recordings, drafts, and internal videos are not uploaded to a remote server.
Built-in preview before export
Preview the original video in the browser, check the total duration, and confirm that your selected time range makes sense before trimming.
Common format support
Upload MP4, MOV, WebM, or MKV source files for lightweight browser-side trimming without installing desktop software.
Stable MP4 output
The first version exports trimmed clips as MP4 for broad playback compatibility across phones, browsers, messaging apps, and social platforms.
No account and no upload queue
Open the page, choose a file, trim the part you want, and download the result. There is no signup flow, no waiting room, and no server queue.
Why use this video trimmer
Most people do not need a full editor just to remove a rough opening or keep a short highlight. A focused video trimmer is faster, clearer, and easier to trust when the job is simply keeping one clean segment.
How to trim video online
Use this six-step workflow when you want a clean trimmed clip without opening a heavyweight editor
Step 1 — Upload your video file
Open the video trimmer, click the upload area, or drag your file into the page. The first version accepts common local video files such as MP4, MOV, WebM, and MKV. After selection, the page creates a local preview so you can confirm that you chose the right source clip.
Step 2 — Check the total duration
Wait for the preview player to load the video metadata. Once the duration is available, you can see how long the original clip is and decide which exact section you want to keep. This helps you avoid trimming past the end of the file or keeping unnecessary blank sections.
Step 3 — Enter the start time
Type the moment where your final clip should begin. For example, if the first eight seconds contain dead air, set the start time to 8.0. If you want to skip a title slate, a webcam adjustment, or the words before the real answer begins, trimming from a later start point removes that friction immediately.
Step 4 — Enter the end time
Type the exact moment where the kept section should stop. This is useful when you want to cut away trailing silence, remove the outro, stop before unrelated conversation begins, or isolate a short social clip from a longer video. The end time must be later than the start time, and it should stay within the actual video duration.
Step 5 — Trim the clip locally
Click the trim button to start processing. FFmpeg.wasm handles the job in your browser instead of sending the file to a server. The progress bar shows how far the trimming task has advanced, and the page keeps the workflow simple by focusing on one task: exporting the chosen section as a clean MP4 file.
Step 6 — Download and review the result
When the trim finishes, download the output file named with your original filename plus -trimmed. Play the result once to confirm the cut points feel right. If you need a different frame area afterward, use a cropper; if you need a smaller file size, use a compressor; if you need another format, use a converter.
This first version of Video Trimmer accepts common video uploads that people already use in daily work: MP4, MOV, WebM, and MKV. That coverage handles most screen recordings, exported presentation clips, camera files that were already transcoded for sharing, and short-form assets pulled from browser-based workflows. The practical goal is not to support every obscure codec combination on day one. The goal is to cover the mainstream formats that are most likely to appear when someone needs a quick time cut in the browser.
The output strategy is intentionally simple: export the trimmed result as MP4. That gives you a file that is easier to play in browsers, easier to send in chat tools, and easier to reuse in other publishing steps. If your next task is reducing size, go to Video Compressor. If your next task is changing file format, go to MP4 Converter. If your next task is reframing the visible image area, that is a cropper job rather than a trimmer job.
A lot of trimming work involves content you would rather not upload: customer demos, internal product walkthroughs, interview drafts, class recordings, training clips, or family videos. This page is built around browser-local processing, which means the trim job runs on your device instead of sending the video to a remote processing queue. That makes the tool more practical when privacy, review speed, and control over the source file all matter at the same time.
Local processing also changes expectations in a useful way. You are trading advanced timeline controls for a lighter workflow that starts immediately and keeps the file closer to you. For quick edits, that is often the right trade. You do not need a complicated interface to remove ten seconds of empty setup or keep one strong answer from a longer recording. You need a stable tool that explains what it does clearly and gets out of the way once the clip is ready.

I often record walkthroughs for customers and only need the useful middle section. A full editor is overkill. A clean start-time and end-time trimmer is exactly what I want for those handoff clips.
Marcus Reed
Course Creator
Sometimes a lesson recording starts with thirty seconds of setup. I just want to remove that and publish the useful part. Browser-local trimming is a better fit than uploading training footage to another service.
Aya Sato
Social Media Editor
For quick social clips, I usually already know the time range I need. Typing the start and end points is faster than opening a timeline editor when the goal is just isolating one highlight.
Leo Martin
Sales Engineer
Demo videos often have awkward pauses at the front and back. A lightweight video trimmer helps me clean those clips before sending them to prospects without involving our full post-production workflow.
Jasmine Wong
Recruiting Coordinator
We trim interview practice videos to keep only the answer portion. The local processing angle matters because we do not want to upload candidate recordings to tools we do not control.

The difference between trimming and cropping confuses people all the time. A page that focuses on time cuts only is useful because it keeps the tool and the explanation aligned.
Video Trimmer FAQ
What does a video trimmer do?
A video trimmer keeps only the section between your chosen start time and end time. It is for cutting time from a clip, not for changing the visible frame area, adding effects, or building a multi-scene edit. If your goal is to remove the first few seconds, cut off the ending, or keep one highlight section, trimming is the right tool.
What is the difference between trimming and cropping?
Trimming changes time. Cropping changes the visible dimensions of the frame. If you want to remove the opening and ending of a clip, use a video trimmer. If you want to cut out the left and right sides of the image, remove empty borders, or reframe vertical and horizontal composition, you need a video cropper instead.
What is the difference between trimming and compressing or converting?
Trimming decides which part of the clip stays. Compressing reduces file size, often by lowering quality or changing encoding settings. Converting changes the file format, such as turning MOV into MP4. In real workflows you may trim first, then compress for size, or convert later for compatibility, but they solve different problems.
Is this video trimmer private?
Yes. The trim process runs locally in your browser using FFmpeg.wasm, so the page is designed around browser-side processing rather than server uploads. That makes it more suitable for internal demos, private recordings, draft interviews, and personal clips that you do not want to send to a third-party backend.
Which formats can I upload and what format do I get back?
The first version is built for common inputs such as MP4, MOV, WebM, and MKV. For predictable playback and easier sharing, the trimmed output is exported as MP4. This keeps the tool simple and practical, especially for users who want a clip that opens reliably in browsers, phones, team chat apps, and social publishing workflows.
Is this enough for professional editing work?
No. This page is intentionally a lightweight trimming tool, not a professional non-linear editor. It is good for removing intros, cutting endings, isolating one highlight, and preparing a simpler clip for sharing. If you need multiple cuts, transitions, layered audio, subtitles, or color work, you should move to a dedicated editing application.
