How to resize a video for Reels and TikTok

  1. 1

    Drop your video

    Landscape, portrait or square — any source works.

  2. 2

    Pick the shape

    9:16 for Reels, TikTok and Shorts, 1:1 or 4:5 for the feed, 16:9 for YouTube.

  3. 3

    Choose the fill

    Blurred copy of your video, a solid colour, or crop to fill the whole frame.

  4. 4

    Export

    You get a 1080-wide video that uploads without black bars or cropping surprises.

Popular ways to use it

Landscape to Reels

Post a horizontal clip as a Reel with a stylish blurred background instead of black bars.

Square feed posts

1:1 fills more of the feed on Instagram and Facebook than 16:9.

Brand colour frames

Put your video on your brand colour for a consistent, recognisable look.

Shorts from long videos

Combine with Trim to turn a YouTube segment into a vertical Short.

Tips for the best result

  • Blur fill keeps the whole picture visible — best when people are near the edges.
  • "Crop to fill" is best for talking heads centred in the frame.
  • Add text near the top or bottom so it sits in the fill area, not over faces.

Resize for social — FAQ

What size is a Reel or TikTok?

1080 × 1920 pixels (9:16). That is exactly what the 9:16 preset exports.

Will my landscape video be cut off?

Not with "Blur fill" or "Color" — the whole video stays visible with a background filling the rest. "Crop" fills the frame and trims the sides.

What resolution does it export?

1080 × 1920 for 9:16, 1080 × 1080 for 1:1, 1080 × 1350 for 4:5 and 1920 × 1080 for 16:9.

Will my video look stretched?

Never — the picture always keeps its proportions. The extra space is filled with blur or colour, or the edges are cropped.

Can I add music and captions too?

Yes. Stack "Add music" and "Add text" and everything is applied in the same export.
