About this tool
Nibras Code Video is a set of free online tools to trim videos, convert formats, make GIFs, merge clips and extract audio. Everything runs directly in your browser with ffmpeg.wasm — no install, no sign-up, no account.
Privacy: your video is never uploaded to any server. The file is processed only in your device's memory, inside the browser, and the result is saved back to your device. We do not see, store, transfer or use your video for any purpose. Temporary data in the browser is cleared when you close the page.
What data is collected? The video tools need no personal data: no name, email, phone or file content. On first use the browser downloads the ffmpeg engine (about 30 MB) — that is program code, not your file. The site may keep anonymous visit counts for general operation; see the Privacy Policy page for details.
In the trim tool you drag start and end handles on a timeline, with frame stepping, zoom and millisecond precision. Accurate cut re-encodes the video to cut exactly where you choose; fast mode cuts on keyframes without quality loss.
Speed depends on your device: short clips finish in seconds on modern phones and computers, while long high-quality videos take longer. Internet is only needed when the tool first loads.

Frequently asked questions
Is my video uploaded to a server?
No. All processing happens in your browser on your device. The file is never sent to Nibras Code servers or third parties.
Do I need an account?
No. The video tools are free, ad-free and work without an account.
What data do you collect?
No personal data or file content is collected for the video tools. Only general anonymous site statistics may exist.
Why is the first load slower?
The browser downloads the ffmpeg engine (~30 MB) once. Later visits usually load faster from cache.
Which formats are supported?
Most formats your browser can open: MP4, MOV, WebM, MKV, AVI and more. Output can be MP4, WebM, GIF or audio (MP3, WAV, M4A).
Can I cut without losing quality?
Yes, fast mode cuts without re-encoding. Accurate cut re-encodes to cut on the exact frame.
Does it work on phones?
Yes, in Android and iPhone browsers. Very large files may be limited by device memory.
Is there a file size limit?
There is no server limit; your device memory and browser set the limit. A few hundred MB usually works fine.
