Frequently Asked Questions
Quick direct-answer guides about using this utility tool locally and securely.
Can I compress large video files?
Yes, you can choose custom reduction scales or target specific pixel resolutions to shrink video files.
Does it support custom dimension resizing?
Yes, you can enter custom target widths and heights to resize the video dimensions.
Is it safe to compress video online using KuberAgent?
Yes, completely safe. KuberAgent's video compressor works entirely inside your browser using local processing — your video file is never uploaded to any server. No data leaves your device, making it 100% private.
How much can I reduce video file size without losing quality?
Using the quality slider, you can reduce video file size by 50–80% while keeping visually acceptable quality. Choosing 720p instead of 1080p resolution alone can cut file size by up to 60%. Results vary by source video content.
Does compressing video require creating an account?
No account is needed. Open the tool, load your video, compress, and download — completely free with no sign-up required.
How long does it take to compress a video?
Compression happens locally in your browser and typically takes a few seconds to a couple of minutes depending on video length, resolution, and your device's processing power. No waiting for server uploads.
Can I compress videos on mobile or tablet?
Yes. KuberAgent's video compressor works on modern mobile browsers including Chrome and Safari on Android and iOS. No app download needed.
What is the maximum video file size I can compress?
The tool processes video in-browser so the practical limit depends on your device's available RAM. Most devices handle files up to 500 MB comfortably. For very large files (1 GB+), use a device with more memory.
Will compressed video work on YouTube, Instagram, or WhatsApp?
Yes. MP4 compressed at 720p or 480p is accepted by YouTube, Instagram Reels, WhatsApp, and most other platforms. Check each platform's recommended specs for best results.
What is the difference between resolution and quality compression?
Resolution compression reduces the number of pixels (e.g., from 1080p to 720p) which lowers file size significantly. Quality compression keeps the same resolution but reduces bitrate using a quality slider. You can use both together for maximum size reduction.
