Turn a set of stills into an animation. Each image gets its own slot on the timeline and its own duration, so a slideshow and a stop-motion loop are the same tool used differently.
Drag in a whole folder — the files stay on your machine.
Everything happens in the tab, so a hundred photos cost nothing to add.
Drop in PNG, JPG, WebP, AVIF or even existing GIFs. They land on the timeline in the order you added them.
Move frames earlier or later, and set how long each one holds — from 40 ms for stop-motion to several seconds for a slideshow.
Pick how mismatched sizes should be handled, choose a background for any letterboxing, then export a GIF, a video or the frames themselves.
Hold the first frame for two seconds as a title card and run the rest at 100 ms. Every frame has its own delay; you are not setting one rate for the whole animation.
Contain, cover or stretch, with a background colour or full transparency behind any letterboxing. Photos straight off a phone and a screenshot can share one canvas without a manual crop pass.
A text layer can be limited to a frame range, so a label appears over the third photo only and disappears again.
The images are already in the tab. Reordering, retiming or removing one re-renders the preview immediately, with no round trip.
The instinct is to give every photo the same duration. It reads better if you do not: a frame with text needs longer than a frame without, and the first frame needs longest of all because the viewer is still working out what they are looking at.
A workable starting point is 1.5 to 2 seconds for the opening frame, 1 second for photos, and 1.5 seconds for anything carrying a caption. Then watch it loop three times and cut whatever felt slow.
GIF stores at most 256 colours per frame. Photographs contain tens of thousands, so every one has to be approximated, and gradients — skies, skin, shadows — are where that approximation gets expensive and ugly at the same time.
Two levers help more than anything else: shrink the canvas, because bytes scale with pixel count, and turn dithering on so the remaining colours are mixed rather than banded. If the result still looks poor, the honest answer is that the material wants a video, and MP4 or WebM export is right there.
