What Photo Slideshow Maker does and how it behaves

Assemble a set of photos into a video slideshow: arrange them in order, set how long each stays on screen, choose a transition between slides, add a music track if you want one, and export the finished sequence as a video file you can download. All the work happens in the browser, so your photos are never uploaded to a server. The thing people most often trip on is the output format: the browser doing the encoding decides it, commonly WebM in Chrome and Firefox and MP4 in Safari, and a WebM file is not accepted everywhere. Check the file extension before sending it anywhere.

How the result is produced

Sequence and timing

Your photos become an ordered sequence, and each slide has a duration you can adjust - you can apply one duration across the whole set, then fine-tune individual slides. The finished video is as long as the sum of the slide durations: ten slides at three seconds each give a thirty-second sequence, and changing one slide changes only its portion.

Transitions and export

Consecutive slides are joined by a transition effect you choose from the tool's options. When you start the export, the browser renders the assembled sequence - images advancing at their set durations, transitions between them, the music track underneath - and encodes it into a video file you can download.

Good uses

A folder of holiday photos needs to become a short video for family who were not on the trip.
Product shots or screenshots need a timed highlight reel for a client or a social post, without installing an editor.
A birthday or retirement tribute with background music is due for an event or an email.

Limits and checks

The output format is chosen by the browser, not the tool: Chrome and Firefox commonly produce WebM, Safari can produce MP4. A WebM file may not play on older hardware or be accepted by every upload form, so confirm the extension before you send the file, and convert if you need MP4.
Transitions can make the timing less obvious than it looks: if a crossfade overlaps the end of one slide into the next, each photo is fully visible for less than its nominal duration. The stated final length is the reliable number - read it, and add a second or two per slide if photos feel rushed.
Nothing stops you from adding a copyrighted song, but platforms that host video run audio fingerprinting and may mute or block a video that uses one. For a video you plan to post publicly, use a royalty-free track or your own recording.

Common questions

Why is the export a WebM file and not an MP4?

The container and codec come from the browser's recording support, not from the tool, so no setting can change it: Chrome and Firefox commonly record WebM, while Safari can record MP4. If you need an MP4, export from Safari or convert the file afterwards with a free converter. The video content itself is the same.

Why does exporting take as long as the video itself?

The browser renders and encodes the slideshow in roughly real time, so a one-minute slideshow takes about a minute to export and a longer one takes proportionally longer. Keep the tab in the foreground while it runs. To speed it up, shorten slide durations or cut photos, since export time follows the finished length.
