Video Tools
ArrayKit's video tools cover the everyday clip-editing jobs right in your browser, so nothing you load is ever uploaded. Convert between MP4, MOV, MKV, AVI and WebM with the Video Converter, then shrink files with the Video Compressor. Trim a clip with the Video Trimmer or slice a long recording into parts with Split Video. Reframe for social with the Video Resizer and Crop Video for 9:16, 1:1 and 4:5, or turn a moment into an animated GIF with Video to GIF — and back again with GIF to Video. Work with sound too: Extract Audio to MP3, Mute Video, or Add Music to swap the track. Grab a still with the Video Thumbnail Generator or Screenshot from Video, and brand clips with Add Watermark to Video. Every tool processes your footage locally on your own device.

Frequently asked questions
- What can I do with ArrayKit's video tools?
- You can convert, compress, trim, split, crop, resize and watermark videos, extract or replace the audio, mute a clip, grab thumbnails and screenshots, and convert between video and animated GIF — 14 tools covering the most common clip-editing tasks.
- Do my videos get uploaded to a server?
- No. Every video tool runs entirely in your browser and processes footage on your own device, so your clips never leave your computer and nothing is uploaded anywhere.
- Which video formats do these tools support?
- The tools work with common formats like MP4, MOV, MKV, WebM and AVI. Output is typically a widely compatible MP4 or a smaller WebM, with GIF and image formats (JPG, PNG, WebP) available where relevant.
- 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 use the video tools?
- No installation is required — the video tools run in any modern browser. Open the tool you need, drop in a file, choose your settings, and download the result.
- Can I edit videos for Instagram, TikTok or YouTube?
- Yes. Use the Video Resizer and Crop Video to reframe clips to 9:16, 1:1, 4:5 or 16:9 for Reels, TikTok, Shorts and YouTube, then trim, compress or watermark them before you upload.
