Resolution means pixel dimensions
Changing resolution changes the output video's pixel dimensions, such as 1920 x 1080, 1280 x 720, or 1080 x 1920.
Best settings and limits
Best first try
Start with 1280 x 720 for HD. Use 1920 x 1080 only when the source is already high quality and your browser can handle it.
When this may fail
Increasing resolution cannot add real detail. Upscaling can make files larger without improving sharpness.
Privacy boundary
The selected video file stays on your device while the tool creates the output.
Frequently asked questions
Is changing resolution the same as compression?
No. Resolution changes pixel dimensions. Compression changes encoding settings and file size.
Can I change resolution locally?
Yes. The selected video is processed in the browser tab.
Can I make 1080p from a small video?
You can upscale dimensions, but it will not restore detail that is not in the source.
