Frequently asked questions
Will resizing change the aspect ratio?
No, the video is scaled proportionally to the resolution you pick.
Does a smaller resolution mean a smaller file?
Generally yes, lower resolutions produce smaller output files.
Can I upscale a low-resolution video?
You can scale up, but quality won't exceed the original footage.
Will resizing affect video quality?
Scaling down keeps quality intact; scaling up stretches existing detail rather than adding new sharpness.
Does resizing change the file format?
No, the output stays in the same format as your original video.
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.
