ArrayKit Video Merger review
Free local browser merger with lossless matching joins and mixed-format handling.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ArrayKit Video Merger is a free web tool that combines two or more video clips into one MP4. It is aimed at solo users and small teams that want to join footage in a browser while keeping files on their own device. Matching clips can be concatenated stream-by-stream without re-encoding, while clips with differing formats or resolutions are processed into a common output. The browser-based workflow suits users who need a straightforward local merger rather than a broader production suite.
Its strongest capability is format-aware joining. Users can reorder clips, see each clip's resolution, and merge matching inputs without re-encoding. For mixed inputs, ArrayKit automatically scales and pads frames, preserves aspect ratios with letterboxing, synchronizes video, and resamples audio. An inline preview lets users review the merged result before downloading. Processing happens on-device, so footage is not uploaded to ArrayKit; that makes the tool a practical fit for local handling of personal or work clips.
The trade-off is a narrow output and platform scope. The published feature set centers on one MP4 output, and mixed-format jobs are encoded to a common result rather than preserving every source stream unchanged. ArrayKit runs on the web, with community support, so users seeking a wider range of export targets or more direct support should consider a different merger. Choose it for free, local browser joins with occasional mixed inputs; look elsewhere when output flexibility or a broader ecosystem is the priority.
