How do I resize a video online?

Upload your video to VFX AI, choose a preset (or custom dimensions), pick how it should fit or crop, then export your resized video in a few clicks.

Can I resize videos for social media platforms?

Yes, you can use presets for TikTok, Reels, Stories, Shorts, Facebook, LinkedIn, and more so you never have to memorize aspect ratios.

Will resizing my video reduce its quality?

You can maintain high quality by selecting the appropriate resolution when exporting (such as 1080p or 4K). VFX AI resizes the canvas while preserving as much detail as possible.

Can I change just the aspect ratio without cropping important parts?

Yes, you can fit with borders or use smart reframing so the main subject stays visible, rather than cutting off faces or text.

Do I need editing experience to resize videos?

No, presets and simple controls mean you can resize videos even if you're not an editor, just pick the platform and export.

Why Smart Resizing Matters For Your Content

Every platform has its own sizes and aspect ratios. Resize helps you adapt a single video to multiple formats without rebuilding your edit from scratch.

Make One Video Fit Every Platform

Convert a single 16:9 video into multiple sizes and ratios: vertical, square, or custom sizes for Shorts, Reels, TikTok, Stories, and Feed in just a few clicks without needing separate edits for each platform.

Smart reframing keeps the subject centered in frame

Keep The Right Parts In Frame

Use fit, crop, and smart reframing options to keep faces, products, important parts, and captions visible after resizing content from a long form video so nothing important gets cut or hidden.
