TikTok Image & Cover Resizer

Resize a photo to TikTok's 1080 × 1920 vertical cover size — free, instant, entirely on your device.

How to resize an image for TikTok

Drop a photo into the box above and it's automatically center-cropped to the 9:16 vertical ratio and scaled to 1080 × 1920 pixels — the full-screen size TikTok uses for video covers and vertical image posts — then offered for download.

For example, a horizontal photo taken for a different platform will have its sides trimmed to fit this tall frame, so the main subject stays centered on screen instead of being squeezed.

Why full-screen vertical matters on TikTok

TikTok is viewed full-screen and vertically by default, so any cover image or photo post not shot or cropped to 9:16 gets padded with black bars or blurred edges. Pre-cropping to this ratio here ensures your image fills the entire screen exactly as intended.

Sizing cover images and photo posts for TikTok

TikTok is built entirely around the full-screen vertical frame, and that extends to video cover images and photo-mode posts too — an image sized for a landscape or square feed elsewhere will show up letterboxed or heavily cropped in TikTok's app. Resizing to TikTok's tall aspect ratio beforehand keeps your cover image or photo post filling the screen the way viewers expect.

As with Instagram Stories, keep in mind that TikTok's own interface — captions, like and share buttons, the sound track — sits along the right edge and bottom of the screen, so avoid placing important text or logos directly behind where those controls typically appear.

Designing for a screen people hold, not scroll past

TikTok's format assumes the viewer is holding their phone upright and watching full-screen, which means a properly sized vertical image reads as intentional in a way a cropped or letterboxed one never quite does — even for a static cover image rather than video content, matching the platform's expected proportions makes a real difference in how polished a post looks.

This tool resizes entirely within your browser using the Canvas API, so you can check how your image looks at the correct vertical proportions before uploading anything.

A quick check before uploading

Viewing your resized image at actual phone-screen proportions, rather than zoomed in on a desktop editor, is the best way to judge whether the composition still works — details that look fine on a large monitor can feel cramped or oddly placed once seen at the size a viewer will actually experience them.
