Dimensions affect quality and upload fit
Video dimensions are the pixel width and height of the frame. They help you choose resize settings, crop ratios, and compression limits.
Best settings and limits
Best first try
Choose a video and run the check. Use resize for exact dimensions or crop for square and vertical formats.
When this may fail
The browser must be able to read the video's metadata. Some unusual containers may not expose dimensions reliably.
Privacy boundary
The selected video file stays on your device while the tool creates the output.
Frequently asked questions
Are video dimensions the same as resolution?
Yes. Both refer to the video's width and height in pixels.
Does checking dimensions upload the file?
No. The browser reads local metadata from the selected file.
What should I do if dimensions are too large?
Use resize to lower dimensions, or compress with a lower max height.
