Xargaar ToolsMake the video smaller. Keep it on your computer.
Shrink, trim and convert MP4, MOV, WebM and MKV videos in this page. The file is never uploaded, there is no watermark and no account. The free version handles up to 5 minutes of video, in files up to 500 MB, per run.
Pause the preview where you want, then press a button. Or type the seconds.
How it works
MP4, M4V, MOV, WebM or MKV (screen recordings work). The page reads it in pieces from your disk. Nothing is sent anywhere.
Choose a quality level, or type a size like 10 MB. Optionally cut a smaller picture size, a lower frame rate or a trim.
The picture is re-encoded as H.264 in your browser. AAC and Opus sound is copied unchanged. Other audio formats are omitted; check the warning and preview.
No limits. Works offline.
- The free page compresses up to 5 minutes of video in files up to 500 MB per run. The pack removes those limits. Very large videos depend on your computer's memory.
- One folder you keep. Open index.html in current Chrome or Edge. No install, no account, no internet needed.
- No watermark in either version.
Planned one-time price.
Offline pack in preparation. Not yet for sale.
Questions
Is my video uploaded?
No. The video is read and re-encoded by code running in this page, using your own computer. There is no server that receives it. You can go offline after the page loads and it still works.
Is there a watermark?
No. Nothing is added to your video.
Which files and browsers work?
Input is MP4, M4V, MOV, WebM or MKV. The picture must be in a format your browser can decode (H.264, VP8, VP9 and AV1 where supported; HEVC from iPhones only works if your browser and computer can decode it). Output is always MP4 with H.264 video. It works best in current Chrome or Edge on a computer. The page checks your browser and tells you if it cannot run. We have not tested phones.
Can it read WebM, MKV or AVI?
WebM and MKV yes, including screen recordings from Chrome and OBS. AVI and WMV no, because browsers cannot decode them. The page tells you if a file cannot be read.
What happens to the sound?
AAC sound (most phones and cameras) and Opus sound (WebM screen recordings) is copied into the new file untouched, so it is not made worse and not made smaller. You can remove the sound to save a little more. Other sound formats are left out, and the page tells you.
How accurate is the target size?
It aims a little under the size you type. Real results land within some percent of it, depending on the video. If it comes out a bit over, ask for a slightly smaller size and run it again. A video that is already small or very static may not shrink further.
Is there a limit on file size?
The file is read in pieces. In Chrome and Edge, a large result is written straight to a file you choose, so memory is not the limit. In other browsers the finished video is built in memory, so very large files need free memory. The free version handles files up to 500 MB.
Does the picture lose quality?
Yes, compressing always loses some detail. Balanced is meant for sharing and watching. Higher quality keeps more detail and makes a bigger file. Always look at the preview before you use the result.
