Frequently asked questions
Which video formats can I convert between?
Upload MP4, WebM, MOV, MKV or AVI, and convert to any of the same five formats.
Which quality setting should I choose?
Maximum keeps the most detail but makes the largest file; Standard shrinks the file more at some quality cost. High is a good default for most videos.
Is my video uploaded anywhere?
No, conversion happens entirely in your browser — nothing is sent to a server.
How long does converting take?
It depends on the video's length, resolution, and the quality level you pick — longer or higher-quality conversions take more time since everything runs on your own device.
Is there a file size or length limit?
No hard limit — since everything runs in your browser, the practical ceiling is your own device's memory, not a server quota.
Your files are never uploaded. Gotool.xyz runs entirely as JavaScript in your browser. Your files are processed in memory and never touch a server — nothing to breach, nothing to clean up. Close the tab and it's like it never happened. The only thing we count is which tool ran (just the name, e.g. "merge") so we know what people find useful — never your file, its name, its size, or anything in it.
