Resize Video
Scale supported video to a target resolution with fit (letterbox), fill (crop), or stretch modes. Available codecs and hardware acceleration vary by browser and device.
Standard ladders
One-click 1080p / 720p / 480p plus vertical 9:16 and square 1:1 presets.
Three fit modes
Fit pads with black bars, fill crops to cover, stretch ignores aspect — you choose.
Managed bitrate target
The H.264 path targets about 0.1 bits per pixel; output size and visible detail vary with the source, dimensions, encoder, and browser.
How to resize a video
- Open the tool and add your video Select a compatible file for Resize Video.
- Review and adjust Choose a target resolution (1080p, 720p, 480p or a custom size) and a fit mode.
- Export and download Review the exported result from Resize Video, then download it.
Frequently asked questions
Will resizing blur my video?
Resizing can soften detail, especially when enlarging or using a low output bitrate. Standard upscaling stretches existing pixels; the AI Video Upscaler can propose learned detail, but its result also depends on the source.
Can I convert vertical to horizontal?
Yes — pick a 16:9 preset with fill mode, or use the Reels resizer for the opposite direction.
Is the audio re-encoded?
When compatible passthrough is available, the audio track is copied without audio re-encoding. Check the export because support varies by input and browser.
What's the difference between fit, fill and stretch?
Fit pads to preserve aspect ratio; fill crops to cover the target; stretch forces the target dimensions and may distort the image.
Can I resize without losing quality?
Any pixel resize can change detail, and the export may be re-encoded. Downscaling usually preserves more apparent sharpness than enlarging; review the output at its target size.
