Resizing Features

Resize videos to any dimension while maintaining optimal quality. Advanced scaling algorithms including Lanczos, bicubic, and bilinear ensure sharp results whether upscaling for 4K displays or downscaling for mobile. Intelligent enhancement for upscaling prevents pixelation.

Convert between any aspect ratio with multiple handling options. Add letterbox bars, crop to fill, or stretch to fit. Perfect for adapting content between platforms - convert horizontal videos to vertical for Stories, or widescreen to square for Instagram posts.

One-click presets for every major platform: YouTube (1080p/4K), Instagram (square/vertical), TikTok (9:16), Twitter, Facebook, and more. Each preset optimizes not just dimensions but also bitrate and codec settings for best platform performance.

Reduce file sizes dramatically through intelligent resizing. Downscaling 4K to 1080p can reduce file size by 75% while maintaining excellent quality. Perfect for email attachments, faster uploads, or reducing storage needs without visible quality loss.

Frequently Asked Questions

When downscaling (making smaller), quality is preserved perfectly - you're just using fewer pixels to represent the same information. When upscaling (making larger), we use advanced algorithms and optional AI enhancement to minimize quality loss, though the result depends on the original video's quality.
Upload your horizontal video and select a vertical preset like 9:16 for TikTok. Choose how to handle the aspect change: 'Crop to Fill' cuts the sides but fills the frame, 'Letterbox' adds blurred bars while showing everything, or 'Zoom & Pan' lets you select which part to focus on.
Instagram: 1080×1080 (square) or 1080×1350 (portrait). TikTok/Reels: 1080×1920 (9:16). YouTube: 1920×1080 (16:9) or 3840×2160 (4K). Twitter: 1280×720 minimum. We have presets for all platforms that automatically apply the optimal settings.
Absolutely! Resizing is one of the most effective ways to reduce file size. Converting 4K to 1080p typically reduces size by 75%, while 1080p to 720p saves about 50%. The visual difference is often negligible on smaller screens, making this perfect for email attachments or faster uploads.
Generally, edit first at the highest quality, then resize as the final step. This preserves maximum quality throughout your editing process. However, if working with very large 4K/8K files that slow down your editor, creating smaller proxy files for editing can improve workflow.
