FAQ

Video Tools FAQ

Are these video tools really free?+
Yes, all video tools are completely free to use with no hidden costs. There are no watermarks, no file limits, and no account required. The tools run entirely in your browser.
Do my videos get uploaded to a server?+
No. All video processing happens locally in your browser using FFmpeg WebAssembly technology. Your video files never leave your device, ensuring complete privacy.
What video formats are supported?+
MacroKit supports all major video formats including MP4, WebM, MKV, AVI, MOV, WMV, FLV, 3GP, MPG, OGV, M4V, and GIF. You can convert between any of these formats.
What is the maximum file size I can process?+
You can process video files up to 500MB. Since processing happens in your browser, performance depends on your device's memory and processing power.
Can I use these tools on my phone?+
Yes, all tools are fully responsive and work on mobile devices. However, video processing is memory-intensive, so a desktop or laptop will give the best experience for larger files.
What is Fast Mode in the video splitter?+
Fast Mode splits video instantly by cutting at keyframes without re-encoding. This means the output keeps the original quality and format, but cut points may snap to the nearest keyframe (within a few frames of your chosen time).
