Resize Image for TikTok Online

Almost everything on TikTok is judged against the same 9:16 vertical frame, so it looks like a simple platform to design for compared to something like Facebook or LinkedIn with five or six different formats. In practice, the one format TikTok does use gets reused in more than one place, and each place crops it differently. A video cover uploaded at 1080 by 1920 pixels fills the full vertical frame when someone opens the video, but that same image also appears as a square thumbnail in your profile grid once you scroll away from the video itself. TikTok generates that square version by cropping the center of your vertical cover, which means anything positioned near the top or bottom of your original image, like a title card or a subtitle, disappears entirely from the grid version.

The practical fix is to design the cover with your subject and any key text sitting inside the middle third of the frame rather than spread across the full height. If you center a face or a product in the vertical 1080 by 1920 canvas, that same element lands correctly inside the square crop too. Text is the riskier element here. A title placed near the top of a vertical cover reads fine in the full video view but gets cut off in the grid thumbnail, so keep any text you want visible everywhere within roughly the central 1080 by 1080 pixel square of the canvas.

Where TikTok's on-screen elements actually sit

TikTok overlays its own interface on top of every video and photo post, and this overlay covers a predictable portion of the frame regardless of what content is underneath it. The bottom 15 to 20 percent of the frame is reserved for the username, caption text and sound information. The right edge, roughly the outer 15 percent of the frame, carries the like, comment, share and follow buttons stacked vertically. Anything you place in either zone will be partially or fully covered while someone is actively viewing the content. A safe working area for a 1080 by 1920 canvas is the central 1080 by 1420 pixel block, which leaves about 250 pixels of clearance at the bottom and 150 pixels along the right edge. Keeping captions, logos and calls to action inside that block means they stay visible no matter how a particular viewer's interface is laid out.

Photo Mode posts follow the same rules as video covers

TikTok's Photo Mode, sometimes called photo posts or slideshow posts, lets you publish up to 35 still images in a single post instead of a video. These images fill the screen at the same 1080 by 1920 vertical ratio as a normal video, and the same UI overlay from the caption and side buttons applies to every image in the set as someone swipes through it. Photo Mode content built from square or landscape source images ends up with visible black bars on a platform where the entire feed is otherwise full screen, which is a noticeable contrast against the vertical posts surrounding it. Cropping each image to 9:16 before uploading, rather than letting TikTok pad it automatically, keeps a Photo Mode post looking consistent with the rest of the feed.
