ℹ
Honest size expectations. A preset changes the actual encoding choices that affect delivery size; it does not promise a fixed percentage saving. Results depend on the source codec, duration, resolution, frame rate, movement, audio, and your device. Local processing is powered by FFmpeg.wasm.
Delivery Profiles
Pick a Purpose, Not a Guess
Start with a website use case, then use Custom when you need tighter control.
Website hero
A practical default for short promotional or branded sections: up to 1080p, balanced H.264 quality, and audio preserved.
Landing page
A more compact 1080p export for general marketing embeds where download weight matters alongside appearance.
Background loop
A muted 720p export for decorative autoplay video. Keep loops short and provide a still image or poster where appropriate.
Custom
Select the maximum resolution, quality, frame-rate cap, and audio state yourself for a specific publishing requirement.

Questions
Frequently Asked
No. The video engine runs in the current browser tab. IKAI Tools does not receive or retain the selected video.
Not necessarily. The file can be larger if the source was already efficiently compressed or the selected output settings require a different codec. Review the before-and-after values before downloading.
Encoding runs using browser memory, not a server queue. Each file is limited to 100 MB and a queue is limited to five files or 300 MB total, with files processed one at a time. Use a desktop production tool for long or very large videos.
