Resize Images for TikTok — Fill the 9:16 Screen Without Cropping
Turn landscape or square photos into full-screen 9:16 images for photo posts and video covers. AI adds the missing top and bottom.
Built for creators and small brands posting photo carousels and covers on TikTok.
Landscape Photo to TikTok 9:16
The road scene stays whole. AI builds the sky and foreground that a full-screen 9:16 frame needs.
TikTok is a full-screen vertical app: photo posts and videos are designed for 9:16, usually 1080 × 1920 px. A landscape or square photo posted as it is sits small in the middle of the screen with empty space around it, and cropping it to 9:16 throws away most of the picture. ExpandMyImage keeps your whole photo and generates new background above and below it, so the image fills the screen.
AI expansion, not stretching
The original image remains the source of truth. ExpandMyImage grows the canvas around it so the final frame fits a supported social ratio.

FAQ
Answers to common questions before you start expanding images.
What is the best image size for TikTok?
TikTok is built for 9:16 vertical images, and 1080 × 1920 px is the common size for photo posts and covers. Images that are not 9:16 appear with empty space around them or get cropped.
How do I make a photo fit TikTok without cropping?
Upload the photo to ExpandMyImage and choose 9:16. The AI keeps the full photo and generates new background above and below it (or at the sides of a very tall image) until it is exactly 9:16. Download it and add it to your post.
Why does my photo look small on TikTok?
Its shape does not match the 9:16 screen. A landscape photo is much wider than the screen, so TikTok shrinks it to fit the width and leaves space above and below. Expanding the photo to 9:16 first fixes this.
Can I use the result as a TikTok cover?
Yes. The output is 9:16, the same shape as a vertical video. Keep the subject near the center, because TikTok places the caption and buttons along the bottom and right side of the screen.
Will the output be exactly 1080 × 1920 px?
It will be exactly 9:16, but the pixel size depends on your original image. TikTok scales 9:16 images to the screen without cropping. If you need exactly 1080 × 1920, resize the download in any editor; the shape already matches.
Can I try it for free?
Yes. Eligible new users get free credits with no credit card required. More credits are available as one-time packs or a monthly subscription.
