Video Tools
ArrayKit's video tools handle common video chores right in your browser, without uploading a single file to a server. Use the Video Compressor to shrink MP4, MOV, MKV, WebM and AVI files — pick a target quality, resolution and output format, and the tool re-encodes the clip locally so it is smaller and easier to email, upload or embed. There is no imposed file-size limit, and a live activity monitor shows progress and memory use while it works. These tools are built for developers, creators and anyone who needs a smaller video but cares about privacy: every clip is processed on your own device, so nothing you load is ever uploaded. Drop a file in, choose your settings, and download the result in seconds.

Frequently asked questions
- What can the ArrayKit video tools do?
- Right now the Video Compressor re-encodes and shrinks MP4, MOV, MKV, WebM and AVI files, letting you trade quality for a smaller size and optionally downscale the resolution or drop the audio track. More video tools will join the category over time.
- Are the video tools private and safe to use?
- Yes. Every video tool runs entirely in your browser and processes your clip on your own device, so your files never leave your computer and nothing is uploaded to a server.
- Is there a limit on video size or length?
- There is no imposed file-size limit, so you can load clips of any length. The practical ceiling is your device's memory, since the work happens locally in a single browser tab.
- Do I need to install anything to compress a video?
- No installation is required — the video tools run in any modern browser. Open the page, drop in a file, choose your settings, and start compressing.
- Which video formats can I work with?
- The Video Compressor accepts common formats like MP4, MOV, MKV, WebM and AVI, and can output to MP4 for wide compatibility or WebM for smaller files.
