Fit and Fill solve different problems
See the tradeoff before you resize, so the exported frame matches your intent.
Fit keeps the whole video
The complete picture stays visible. Empty space is added when the source and target shapes differ.
Fill covers the whole frame
The frame has no empty space. Edges are cropped when the source and target shapes differ.

Know the difference
Resize, crop, or compress?
Crop removes part of the picture
Use Fill and the focus control when the new frame should have no empty space.
Compress reduces file size
Compression targets storage or transfer size; it does not primarily change the frame shape.
Need another output format?
Use Video Converter to change the file format after resizing.
Resize video FAQ
Is my video uploaded to a server?+
No. Your source video is processed in this browser tab and is not uploaded to Editing.video.
What is the difference between resizing and cropping?+
Resizing changes the output frame dimensions. Cropping removes image content; Fill may crop edges to cover the selected frame.
Will resizing stretch my video?+
No. Fit preserves the full picture and may add space. Fill preserves proportions and may crop edges instead of stretching the image.
Does resizing reduce file size?+
A smaller frame often produces a smaller file, but final size also depends on duration, format, quality, and audio.
Can I make a low-resolution video sharper?+
You can upscale the frame, but resizing cannot restore detail that is missing from the source video.
Can I download the resized video?+
Yes. When processing finishes, download the resized file from this page. Speed and available formats depend on your browser and device.
