Resize Images for TikTok
TikTok is built for full-screen vertical video, and anything that is not 9:16 gets letterboxed or cropped in the feed. The safe size for covers, photo posts, and slideshow images is 1080 by 1920 pixels. Resize to those exact dimensions before you upload so your framing stays intact.
Resize to 1080×1920TikTok image sizes
| Use | Dimensions | Ratio | Notes |
|---|---|---|---|
| Video cover / photo post | 1080 × 1920 px | 9:16 | Full-screen vertical. Keep captions clear of the bottom 20% where the UI sits. |
| Slideshow image | 1080 × 1920 px | 9:16 | Every slide shares one ratio, so size them all the same before posting. |
| Profile photo | 200 × 200 px | 1:1 | Displays as a circle, so keep the subject centered. |
| In-feed ad | 1200 × 628 px | 1.91:1 | Used for image ads that appear outside the vertical feed. |
How it works
Add your image
Drop in any JPG, PNG, or HEIC. Everything runs in your browser, so the file never leaves your device.
Resize to 1080×1920
The tool scales your image to cover the full 9:16 frame and center-crops the overflow, so nothing looks stretched.
Check the safe area
TikTok overlays your username, caption, and buttons on the lower right. Keep important detail away from that corner.
Download and post
Save the resized image and upload it straight to TikTok at native quality.

Tips that make a difference
Match the ratio, not just the width
A 1080px-wide image that is too short still gets cropped. Use the full 1080 by 1920 frame to control what stays in view.
Keep covers legible small
Feed thumbnails are tiny. Big, high-contrast text on a cover reads far better than fine print.
Compress before uploading
TikTok recompresses large files. Getting close to 1MB first keeps your image sharper after their pass.
Frequently Asked Questions
What size should a TikTok photo be?
1080 by 1920 pixels, a 9:16 vertical ratio. That fills the screen without letterboxing on both photo posts and video covers.
Why does my TikTok image look cropped?
TikTok crops anything that is not 9:16 to fit the vertical feed. Resizing to exactly 1080 by 1920 before uploading puts you in control of the crop.
Do you upload my image to a server?
No. Resizing happens locally in your browser, so your image never touches a server.
