New resolution (aspect ratio kept, height adjusts automatically)
Runs on a real video engine loaded into your browser (FFmpeg, compiled to WebAssembly) — about 30MB, downloaded once and cached for the rest of this visit. Nothing is uploaded; resizing happens on your device. Scaling up won't add real detail — the picture will just be softer at a higher resolution, not sharper.
How it works
- Upload the video you want to resize.
- Pick a target resolution — 1080p, 720p, or 480p.
- Resize and download the new file.
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.
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.
