Video Trimmer: Cut a Video Clip to a Start and End Time Online
Short answer: To trim a video, load it, set the time where the clip should start and the time where it should end, then export. With the free Minciter Video Trimmer, you do all of that in your browser. Nothing is uploaded, nothing is installed, and no watermark is added.
Most people searching for a video trimmer want one of three things. They have a long recording and need one short moment from it. They need to shorten a clip so it fits an upload limit. Or they want to remove a shaky start and a rambling end before sharing. This guide covers all three, explains the one technical detail that decides how accurate your cut will be, and shows other ways to trim on your phone and computer.
Your trimmed clip
How to trim a video with the Minciter Video Trimmer
- Open the Minciter Video Trimmer and drop your video onto the box, or click it to choose a file.
- Play the preview and pause where you want the clip to begin. Click “Use current frame” next to Start time.
- Play on to the moment where the clip should end, pause, and click “Use current frame” next to End time.
- Fine-tune if needed. You can drag the sliders or type exact times such as 1:23.5 or 83.5. Both formats work.
- Click “Preview selection” to watch only the part you chose. If the cut feels early or late, adjust and preview again.
- Pick an output size and quality, and decide whether to keep the audio.
- Click “Trim video”, wait for the progress bar to finish, preview the result, and click “Download trimmed video.”
Two things are worth knowing before you start. The tool trims at normal playback speed, so a 60-second clip takes about 60 seconds to process. Keep the tab open and visible while it runs, because browsers slow down background tabs. And depending on your browser, the file is saved as MP4 or WebM. Browsers that can record MP4 produce MP4. The rest produce WebM, which plays in Chrome, Edge, Firefox, VLC and most phone players.
Trimming, cutting and splitting: what is the difference?
People use these words loosely, so here is how they are used on this page. Trimming means keeping one continuous piece of a video by removing the unwanted start, end, or both. Cutting usually means removing a section from the middle. Splitting means dividing one video into several parts. The Minciter tool does the first one: you choose a start and an end, and you get one clean clip.
If you need to remove something from the middle, trim twice (the part before it and the part after) and join the pieces in an editor such as Clipchamp or Shotcut.
Why some trimmers are frame-accurate and others are not
This is the detail most guides skip, and it explains why two trimmers can give different results on the same video.
Video is stored as groups of frames. Each group starts with a keyframe, which is a complete picture. The frames after it only store what changed. A player cannot start decoding in the middle of a group, because it needs the keyframe first.
That creates two ways to trim:
Lossless trimming (stream copy). The tool copies the existing data without re-encoding it. It is instant and loses no quality. The catch is that the cut can only start on a keyframe. If you ask for 10 seconds and the nearest earlier keyframe sits at 8 seconds, your clip begins two seconds early.
Re-encoding. The tool decodes the video and encodes the new clip from scratch. It can start on any frame, so the cut is exact. The price is time and a small loss in quality, because the video is compressed a second time.
The Minciter Video Trimmer re-encodes. That is why you can start a clip on the exact frame you see in the preview, and why a clip takes as long to process as it does to play. If you need a perfect, lossless copy and do not mind a cut that lands on a keyframe, use a lossless tool instead. The “Other ways to trim a video” section below lists a few.
Choosing the output size and quality
The tool gives you two settings that control the file size. These estimates come from the tool’s target bitrates and include audio at 128 kbps. Real files vary with how much motion is in the video, so treat them as ballpark figures.
| Output size | High | Balanced | Small file |
|---|---|---|---|
| 720p | about 34 MB per minute | about 22 MB per minute | about 13 MB per minute |
| 1080p | about 76 MB per minute | about 48 MB per minute | about 29 MB per minute |
A few practical rules:
- For sharing in chat apps or by email, choose 720p with Balanced or Small file.
- For something you will keep, post, or edit further, choose Original size with High.
- The tool never enlarges a video. If your clip is 720p and you pick 1080p, it stays 720p.
- Uncheck “Keep audio” if you only need the picture. The clip is slightly smaller and plays silently.
A quick example. Say you recorded a 12-minute event on your phone at 1080p and need a 40-second moment to send to a friend. Trim it with Output size set to 720p and Quality set to Balanced. That 40 seconds comes to roughly 15 MB, which sends easily. The original 12-minute file would be many times larger.
Other ways to trim a video
No single method suits every situation. Here are the main options, starting with the ones already on your devices.
On an iPhone
Open the Photos app and select the video. Tap Edit, drag the edges of the preview slider to set your start and end, tap Done, and choose “Save as new video” to keep the original or “Save video” to replace it.
On an Android phone
In Google Photos, open the video, tap Edit, drag the slider edges under the video to shorten it, and tap “Save copy.” On Samsung Galaxy phones, open the video in Gallery, tap the Edit icon, adjust the slider edges, and tap Save.
On Windows
Windows has built-in options. The Photos app includes a video editor with a Trim tool, and Windows 11 includes Clipchamp, where you drag the clip’s edges on the timeline and click Export. Free Clipchamp exports do not add a watermark. If you want an offline editor with no account, Shotcut is a free option you can download at shotcut.org.
With free online tools
Online trimmers upload your video to a server, so file size limits and watermarks matter. Here is how some popular ones compare, as of October 2026, based on publicly available information. Limits change often, so confirm them on each site.
| Tool | Max file size (free) | Watermark on free export | Notes |
|---|---|---|---|
| 123Apps Video Cutter | 4 GB | No | Has a lossless mode that cuts at keyframes |
| Clideo | 500 MB | Yes | No lossless option |
| Kapwing | 250 MB | Yes, removable under some conditions | 720p export on the free plan |
| VEED | 250 MB | Yes | 720p export, 10-minute export limit |
| Canva | 1 GB | No | 1080p export, account needed |
| Adobe Express | 1 GB | No | Adobe account required, 1080p |
| Ezgif | 200 MB | No | Better known for GIFs, handles short clips |
For a lossless cut
If you want zero quality loss and can accept a keyframe-aligned start, use stream copy. The free, open-source LosslessCut app does this with a simple interface. If you are comfortable with a command line, FFmpeg from ffmpeg.org does it in one line:
ffmpeg -ss 00:00:10 -to 00:00:20 -i input.mp4 -c copy out.mp4
To get an exact start instead, drop the “-c copy” part so FFmpeg re-encodes, or use the Minciter Video Trimmer.
Which method should you choose?
Use the Minciter Video Trimmer when you want a quick, exact cut without installing anything, and your video is not private enough to worry about uploading. Wait, that last part is the point: nothing is uploaded, so it also suits personal videos.
Use your phone’s built-in editor for videos already on your phone. It is faster than any website and keeps the original quality settings.
Use a lossless tool such as LosslessCut when the file is large, you need the original quality, and a start that lands a little early is fine.
Use an online editor such as Clipchamp, Canva or Kapwing when you want to do more than trim, such as adding text, music or other clips. Check the free limits first.
Common mistakes when trimming
Closing or switching away from the tab. The Minciter tool needs the tab open and visible while it records. If you switch away, the trim can stall or stop early.
Skipping the preview. Always use “Preview selection” before trimming. It is much faster than finding out after the export that the clip starts a second too late.
Trimming huge files in a browser. Very long 4K videos take a long time and use a lot of memory. For a two-hour 4K recording, use a desktop app. For clips up to a few minutes, the browser works well.
Expecting editing features. This tool keeps one section of one video. It does not merge clips, add text, crop the frame or change speed.
Overwriting the original. Always keep the full original file until you have checked the trimmed version.
Trimming and then compressing repeatedly. Every re-encode loses a little quality. Trim once, at the quality you want, instead of trimming several times in a row.
Troubleshooting
The video will not load. Your browser cannot play that format. Some browsers cannot play HEVC (H.265), which many phones use for .mov files. Try opening the page in Safari, or convert the video to MP4 (H.264) first.
The trimmed clip has no sound. Check that “Keep audio” was ticked. If it was, your browser may not support capturing audio from a page. The tool shows a note when that happens. Try a recent version of Chrome, Edge or Firefox.
The progress bar stopped. The tab was probably in the background. Bring it to the front. If it is stuck, click Cancel and start again.
The file saved as WebM, but I need MP4. Your browser records WebM. Try a recent Chrome, Edge or Safari, which can record MP4, or convert the file afterwards.
The clip is a fraction of a second longer or shorter than expected. The clip ends on the nearest video frame after your end time, so the length can differ slightly from what you typed.
Playback looks different from the preview. If you chose a lower output size or the Small file quality, the picture is more compressed. Choose Original size and High quality to compare.
Frequently asked questions
Is the Minciter Video Trimmer free?
Yes, it is free to use, and it adds no watermark. It also does not need an account.
Does it upload my video?
No. The video is processed inside your browser, on your own device. The file is never sent to a server.
How long does trimming take?
About as long as the clip plays. A 30-second clip takes roughly 30 seconds, and a 5-minute clip takes roughly 5 minutes. Keep the tab open and visible while it works.
Will trimming reduce my video quality?
Slightly. The tool re-encodes the clip so it can start on any frame, which adds a small amount of compression. Choose High quality and Original size to keep the loss minimal. For a truly lossless cut, use a stream-copy tool such as LosslessCut.
What video formats can I trim?
Any format your browser can play. MP4 with H.264 and WebM work in virtually every browser. Some .mov files from phones use HEVC, which not every browser can play.
Can I trim a video on my phone with this tool?
Yes, in a recent mobile browser. For long videos, your phone’s built-in editor in Photos or Gallery is faster.
What is the shortest clip I can make?
The tool needs at least 0.1 seconds between the start and the end.
Can I trim the middle out of a video?
Not in one step. Trim the part before the cut and the part after it as two clips, then join them in a video editor.
