Showing holiday photos to the family or running a slideshow on a screen at an event shouldn't need special software. Pick a folder or drop your photos, choose a transition, add a song if you like, and press play. Everything runs on your own device.

Overview
The viewer plays photos straight from your device. In Chrome and Edge you can choose a whole folder, subfolders included, and photos are ordered by name, so files from cameras and phones (IMG_0001, IMG_0002 and so on) play in shooting order. Other browsers use a standard folder picker that does the same job. You can also drop or paste images, including iPhone HEIC photos, which are converted in the browser just before they're shown.
There are four transitions. Fade cross-dissolves to the next photo, Slide pushes it in from the side in the direction you're moving, and Cut switches instantly. Ken Burns, named after the documentary filmmaker who made it famous, slowly zooms and drifts across each photo. The zoom is 15%, with a random direction and starting point for every slide, which brings still pictures to life on a big screen. Each photo can stay up for 1 to 20 seconds, and transitions can last 0.2 to 2 seconds.
Captions come from the file names, with the extension removed and underscores and hyphens turned into spaces, so a file named “Lisbon_tram-at-sunset.jpg” is captioned “Lisbon tram at sunset”. Rename your files and you have captions. You can shuffle the order, loop forever, or stop at the last photo, and choose whether each photo is shown whole or cropped to fill the screen. Background music plays and pauses with the show and repeats until you stop.
The controls work with a keyboard, a mouse or a touch screen. Use the arrow keys, Space, F for fullscreen, Home and End, S to shuffle and C for captions. On phones and tablets, swipe left or right. In fullscreen, while the show is playing, the buttons and cursor hide after a few seconds without mouse movement. The thumbnail strip lets you jump to any photo; thumbnails are generated only for the photos currently visible, so a folder of thousands doesn't slow things down. To turn your slideshow into a video file, use the Slideshow Maker.
Drop photos onto the page or click Play a folder and choose a folder.
Pick a transition (fade, slide, Ken Burns or cut) and how long each photo stays up.
Optionally add a music file and set its volume, and turn captions, shuffle and loop on or off.
Press Play, then F for fullscreen. Use the arrow keys or swipe to move manually.
Click any thumbnail in the strip to jump straight to that photo.
Use cases
Connect a laptop to the TV, open the holiday folder, choose Ken Burns with an 8-second interval and some music, and let the photos play during dinner.
Loop a shuffled slideshow of guest photos or sponsor images on a screen at a wedding, an open day or a conference booth, with captions from carefully named files.
Use the slideshow as a quick culling tool. Step through a shoot fullscreen with the arrow keys and note the file names that work, without importing anything into a catalogue.
Show a sequence of images, such as a field trip, an art portfolio or historical photos, fullscreen with captions, and advance them manually as you talk.
Pro tips
Answers to common questions about the slideshow viewer.
This viewer plays slideshows live. To export an MP4 with transitions and music, use the Slideshow Maker, which renders the video on your device with ffmpeg.
By file path, using natural sorting, so IMG_2 comes before IMG_10 and subfolders play in alphabetical order. Turn on Shuffle for a random order that changes each time.
Yes. Once the page has loaded, photos, music and transitions all run locally. Nothing is fetched from the internet while the slideshow plays.
Browsers other than Safari can't display HEIC natively, so each HEIC photo is converted to JPEG in the browser the first time it's shown. The next photo is prepared in the background while the current one is on screen.
No. ToolEnhancer processes files on your own device inside the browser. They are never sent to, stored on or seen by our servers.
Yes. The slideshow viewer is free to use with no sign-up, no watermarks and no daily limits.
