Frequently Asked Questions

How do I resize a video for social media?

Upload your video, then choose the aspect ratio that matches the platform where you plan to post it. For example, use 9:16 for TikTok and Reels, 1:1 for Instagram posts, 4:5 for portrait feeds, or 16:9 for YouTube.

You can resize videos for TikTok, Instagram Reels, YouTube, Instagram feed posts, and other platforms that use common aspect ratios. Choosing the correct dimensions helps your video display properly without having to manually enter width and height values for every project.

Will resizing affect video quality?

Resizing changes your video's dimensions, which can affect the final appearance depending on the original resolution and the selected output size.

Before downloading, preview the resized video to make sure the framing and overall quality meet your expectations.

Can I crop and resize a video at the same time?

Yes. When selecting a new aspect ratio, you can choose between Fit and Fill. Fit keeps the entire video visible and may add empty space around the frame, while Fill crops the video to completely fill the selected dimensions.

If you are creating a portrait post for Instagram, 4:5 (1080 × 1350) is often a better choice. Selecting the correct preset helps your video display properly across different platforms.
