    What changes in your video

    Adjust video resolution is meant to do one specific job, not to hide a long chain of automatic changes. Work from the original file and change only what you need. The tool can handle MP4, WebM, AVI, MOV, MKV where the browser and video engine support them, so the exact result still depends on the source video and the setting you choose.

    A straightforward way to use it

    Start with the source video, choose the option that matches what you want to achieve, then run the processing and open the result. There is usually no benefit in changing several technical settings at once. If the first attempt is not right, go back to the source, adjust one relevant option and try again.

    Formats and real-world compatibility

    MP4, WebM, AVI, MOV, MKV are among the formats used by this tool, but an extension alone does not tell the whole story. Containers, video codecs, audio codecs, resolution and frame rate all affect compatibility. For an important file, test the finished video in the player, browser or service where it will actually be used.

    What happens in your browser

    The video is processed in your browser. How long that takes depends on the length and resolution of the source, the operation you ask for and the memory and processing power available on the device. Larger or more complex videos can take longer, so keep the tab open until the job has finished.

    Check the file before you keep it

    Once the processing is complete, open the output and look at the actual file rather than assuming the setting name tells you everything. Check picture, sound, duration, orientation and format where they matter. If something is wrong, return to the original and change only the setting related to that problem before exporting again.
