What Is a TikTok Slideshow?

Updated October 21, 2026 · By the ViralSlides team

Short answer

A TikTok slideshow is a photo post: a set of up to 35 images that viewers swipe through, or let play along with the sound, in the For You feed. It usually has a sound, short text on each slide and a caption. TikTok calls it a photo post and makes it in Photo mode; creators also call it a photo carousel. Slides fill the screen at 1080x1920 (9:16).

If you have swiped sideways through pictures on a TikTok post with a row of dots under it, that was a slideshow. Here is what the format is, what it is called, its limits, and how it differs from a video.

What it is called

TikTok's own name is a photo post, created in Photo mode. Creators call the same thing a slideshow, a photo carousel or a TikTok carousel. They are one format with one set of limits.

How viewers see it

A slideshow appears in the For You feed like any other post. The viewer swipes between images or lets them advance with the sound, and can like, save, share or comment as on a video. Each image is a slide, and the dots show how many there are.

The limits

Up to 35 photos per post (TikTok Help Center, checked October 2026). Photos fill the screen at 1080x1920, a 9:16 shape; other shapes still post but sit inside empty space. Tools that post through TikTok's API send JPEG or WebP photos of up to 20 MB each.

What slideshows are good for

Anything the viewer reads: lists, steps, checklists, comparisons and myth-busting. The viewer controls the pace and every swipe is a small payoff, so slideshows suit tips people save for later. They need no filming or editing, which is why small teams use them to post often.

Slideshow vs Instagram carousel

Instagram's equivalent is the carousel: up to 20 photos and videos per post, in shapes from 1.91:1 to 3:4, so 1080x1350 (4:5) for portrait. A TikTok slideshow can be reused there with a resized copy of each slide.

How slideshows are made

In the TikTok app (tap +, choose Photo, select the images), in any design tool that exports 1080x1920 images, or generated: ViralSlides writes the hook, the slide copy and the caption for your app and renders the slides.
