Video Merger

📖 About this tool

Select several clips and the tool joins them in list order into one video. Reorder with the up/down buttons or remove clips you do not need. Output resolution (1080p/720p/480p), frame rate and bitrate are unified; each clip is scaled and centred on a common canvas so clips of different sizes join cleanly. Processing runs in real time over the total duration, then you can preview and download. Nothing is uploaded. Everything you drop into this tool stays on your own device. The whole job is done by your browser using standard web technologies, so no file is ever uploaded to a server, no account is required, and nothing is stored after you close the tab. That matters when the material is private: screenshots that contain personal information, unreleased product images, recordings of internal meetings, or client footage you are not allowed to share. It also means the tool keeps working offline once the page has loaded, which is useful on a slow connection or on a machine behind a strict firewall. Because processing happens on your own hardware, speed depends on your device: a modern laptop handles large files quickly, while an older phone may need noticeably longer. For the best results, work with the highest quality source you have, since every conversion step can only preserve detail that was already there. If an output looks wrong, try reloading the page and running it again before assuming the file is broken. The interface adapts to the width of the panel it is placed in, so it works the same way on a desktop screen, a tablet and a phone. All controls are labelled in the language of the site you are visiting, and the tool never asks for permissions it does not need. Typical uses include joining footage shot in separate takes, combining an intro, the main part and an outro, and assembling several event recordings into one compilation. All clips are unified to one resolution, frame rate and bitrate, so mixed sources join cleanly.
