- Downscaling from 4K to 1080p typically reduces file size by 60-75% with minimal visible quality loss.
- Always maintain the original aspect ratio to avoid stretched or squished video.
- Upscaling a low-resolution video will not add detail - it only makes pixels larger.
- For social media, use platform-specific presets: 1080x1920 for Stories, 1080x1080 for square posts.
- Resize to any resolution from 4K down to 360p
- Preset resolutions for common platforms and devices
- Custom width and height with aspect ratio lock
- Letterbox, crop, or stretch options for aspect ratio mismatches
- Significant file size reduction when downscaling
- Reduce 4K footage to 1080p for faster uploading and smaller storage
- Resize videos to meet platform-specific dimension requirements

Downscaling to a lower resolution discards some pixel data, but the result looks sharp at the target size. Upscaling does not improve quality.
1920x1080 (1080p) is the standard. Use 3840x2160 (4K) only if your source footage is 4K and you want maximum quality.
Yes. Lock the aspect ratio and only set one dimension - the other will be calculated automatically.
