Slideshow Maker

Sixty holiday photos, a single evening, a finished video

You are back from two weeks in Portugal with 600 pictures on your phone. Your family wants to see them, nobody wants to click through 600 files, and you would rather not install software for a single evening’s project. A slideshow video is the obvious answer: the 60 best shots, a few seconds each, gentle transitions and a little camera motion.

With our free online slideshow maker above you do exactly that, right from your browser. You never upload your own pictures, there is no account, no watermark, and you can create as many slideshow videos as you like. This guide walks through the project in five phases, each ending with a result you can check.

Phase 1: Add your photos and put them in order

Start by adding your photos straight from your computer. JPG and PNG are the usual suspects, and you can add dozens at once, with more later if the story needs them. Every picture appears as a thumbnail in a strip, and this strip is your storyboard.

Now sort. Drag a thumbnail and drop it where it belongs. A good slideshow tells a small story, so think in chapters: arrival, beach days, city trip, last evening. Put your strongest shot first and keep a quiet, wide shot for the end.

A few sorting habits that pay off:

• Group pictures by location or day rather than by the order the camera saved them.
• Alternate wide shots and close-ups so the rhythm does not get monotonous.
• Remove near-duplicates. Three almost identical sunsets feel like a single long sunset.

Result of Phase 1: an ordered strip that reads like a story when you scan it from left to right.

Phase 2: Pick the aspect ratio and the time per photo

Before you style anything, decide where the show will be watched. You can choose from four aspect ratios:

Unsure? 16:9 is the safe default; 9:16 fills a phone screen without black bars.

Then set the display time per slide, anywhere from 1 to 8 seconds. Three to four seconds is a comfortable pace for pictures people have never seen. Two seconds works for fast, music-driven cuts. Six to eight seconds suits a captioned slide or a group shot where viewers want to spot everyone.

Do a quick sum at this point. Sixty photos at 4 seconds apiece is four minutes, which is about the limit of what friends will sit through without a prompt. If the number feels long, cut pictures rather than shortening the time per slide.

Result of Phase 2: a fixed frame and a running time you have actually checked.

Phase 3: Transitions and Ken Burns motion

Transitions decide how one slide hands over to the next. You can choose from seven options: none, crossfade, slide, slide up, zoom, wipe and blur, with a transition duration between 0.2 and 2 seconds.

How they feel in practice:

1. None is a hard cut. Clean and fast, good for rhythmic edits.
2. Crossfade is the classic slideshow look and works with any set of pictures.
3. Slide and slide up push the old image out. They suit travel or step-by-step content.
4. Zoom adds energy, best used sparingly.
5. Wipe has a presentation feel and pairs well with captions.
6. Blur softens the handover and is pleasant for portraits and weddings.

Pick a single transition for the whole show; switching styles every slide looks busy. A duration of 0.6 to 0.8 seconds is barely noticeable, which is usually what you want.

Ken Burns motion is the slow pan and zoom you know from documentaries. Switch it on and the still pictures start to move slightly, which makes the whole thing feel alive. You can choose one of nine camera moves for the entire show or set the option to change per slide, so two consecutive slides never drift the same way. Keep the motion on for emotional, personal content; switch it off for product shots, screenshots or anything where straight lines should stay straight.

Result of Phase 3: smooth handovers and gentle motion, previewed once from start to finish.

Phase 4: Fit the pictures and write captions

Portrait photos in a 16:9 video are the oldest slideshow problem there is. There are two ways to handle it. “Fill frame” scales each picture until it covers the whole frame and crops the overflow, which gives an edge-to-edge, full-screen look. “Whole photo” shows the complete image with space around it, so nothing is cropped. Fill frame suits travel and family shows; whole photo suits artwork and documents.

Every slide can carry its own caption. Use them for the things a viewer cannot guess: place names, dates, who is in the picture, or a one-line joke. Keep them short.

Result of Phase 4: no awkward crops, and context where the pictures need it.

Phase 5: Export as MP4, WebM or GIF

The export step renders everything in the browser and gives you a file to download. Three formats are available:

• MP4 is the format to share. It plays on phones and TVs, in messaging apps, and you can upload it to every video platform. Our slideshow creator encodes it using the browser’s own WebCodecs encoder, available in Chrome, Edge and Safari 16.4 or newer, which in 2026 covers every current version of those browsers. The WebCodecs API on MDN documents how this hardware-accelerated encoding works directly in the browser.
• WebM works in all modern browsers and is a good choice if you embed the video on a website or use Firefox.
• GIF turns the show into an animated image that autoplays almost everywhere, including chats and forums that block video. Keep GIF versions short; GIF uses a palette of 256 colours and the file grows quickly with every slide.

Result of Phase 5: a finished video on your disk, ready to share.

Making a slideshow with music

Photos and music belong together, so you will probably want a track under the pictures. Browsers cannot mix a soundtrack into a GIF, and our video maker exports silent MP4 and WebM as well, so every format behaves the same way. Music is added in the next step, using a video editor.

Open the export in any editor, including the free ones that ship with Windows and macOS, drop your audio file onto the timeline below the video, trim the end, and export again. Since the slideshow already has its final timing, the only decision left is which track. For public posts, use music you have the rights to; royalty-free libraries are the safe route.

For a single picture rather than a whole series, the photo animation tool adds movement to one image, and the GIF maker turns a handful of frames into a compact animated GIF. For a promotional version with text overlays in several sizes, the banner maker covers that.

Frequently asked questions

Is this slideshow maker free, and is there a watermark?

Yes, it is free, and no, there is no watermark. There is also no account and no upload. Use our tool as a web page in your browser; it renders everything locally.

Are there templates, and can I combine photos and video clips?

No templates and no video clips: it is built for still pictures. Templates in online slideshow creators mostly decide fonts, colours and pacing; here you get the same effect by choosing aspect ratio, transition and Ken Burns motion once, and nothing about the result looks like a template everyone has seen.

How many photos should a slideshow have, and how long should it be?

For a family or travel audience, 40 to 80 pictures at 3 to 4 seconds each gives a video of two to five minutes. For social media, aim for 10 to 20 slides and under one minute.

Can I make a slideshow on my phone?

Yes, it works in mobile browsers as well, and 9:16 is made for it. Rendering a long show is heavier on a phone than on a laptop, so keep mobile projects to a few dozen pictures. MP4 export needs a browser with WebCodecs support, such as Safari 16.4 or newer on iPhone; WebM and GIF work everywhere.
