Trim a video down to the part you want
Pick a start and end point and get a clean clip back. Choose a fast lossless cut that keeps the original quality, or frame-accurate timing.
How it works
Choose your video
The clip opens directly in this tab. Nothing is sent anywhere.
Set the cut points
Drag the start and end sliders, or type exact times.
Pick a cut mode
A fast cut copies the original video data and finishes almost instantly.
The clip never leaves the tab
Trimming usually means handing a video to somebody else's machine and waiting for it back. Here the clip is opened by your browser, cut in place, and handed straight back to you. No request is made in between, so there is nothing to intercept and nothing left behind.
- Opened from your disk by your browser — not sent anywhere first.
- Held in the tab while the tool works, then dropped.
- Saved to your device by your browser, not by a link to a server.
- Closing the tab clears the working copy completely.
- No account, so nothing is ever attached to an identity.
- No tracking of what you worked on or what was inside the file.
There is no queue, no render farm and no waiting room. When the tab closes, the clip is released with it. There is a fuller walkthrough of how Filezaar works in the browser if you want the detail, or follow our DevTools guide to verify your file never leaves your device.
What people use it for
Cutting a clip down for a chat
Messaging apps cap how much video they will send. Trimming to the part that matters gets it through without re-shooting anything.
Pulling a highlight out of a long recording
A screen recording or a lecture is mostly waiting. Keep the section that shows the thing and drop the rest.
Preparing footage for a smaller screen
A shorter, lighter clip loads faster on a phone and is easier to pass on.
Rescuing a clip that will not open
When a phone produces a file an editor refuses, one conversion usually makes it openable everywhere.

When something goes wrong
Damaged files, and formats outside the list above, stop with a plain message rather than a spinner that never finishes. A clip that plays in your player will almost always open here.
The container or the video track is not one the browser can read. Try converting it to MP4 first, or use a different copy of the file.
Why not an upload site
An upload-based editor posts your clip to someone else's machine before it does anything. Take that step out and a lot of small annoyances disappear with it.

Questions
Does trimming reduce video quality?
A fast cut copies the original video data without re-encoding it, so the picture is bit-for-bit identical to the source. A frame-accurate cut re-encodes the clip, which is what allows the cut to land on an exact moment rather than the nearest keyframe.
Why did my fast cut start slightly earlier or later than I asked?
A fast cut can only begin at a keyframe — a complete reference frame that the following frames depend on. The cut therefore snaps to the nearest one. If you need exact timing, choose the frame-accurate mode instead.
Is there a length limit?
There is no fixed limit. What matters is your device's available memory, because the whole clip is handled locally in the browser.
Is there a file size limit?
No fixed limit is imposed by the tool. The practical ceiling is how much memory your device has free, because the whole job runs inside this browser tab.
Does it work without an internet connection?
Yes, once the page has loaded. Nothing is fetched while you work, so a dropped connection does not interrupt a run.
Do I need an account or an email address?
No. There is nothing to sign up for, and nothing is ever attached to an identity because no file leaves your device.
