Your photos.
Your slideshow.

Slidaria is a slideshow, a screen saver, and a full-featured photo and video editor in one app.

Your pictures and clips become a calm slideshow — in a window, as a screen saver, or as a finished video. Everything stays on your Mac: no cloud, no tracking, no login.

Everything in one app

Slidaria turns your photos and videos into a quiet slideshow. The moment your Mac takes a breather, the screen saver steps in. And if you feel like editing — cropping a photo, trimming a clip, tweaking colors — it's all in the same app. Set it up once: your sources and profiles travel with you, whichever mode you're in.

Slideshow window

Start it manually — perfect for presentations, gatherings, quiet evenings. Other displays stay usable.

Screen saver

Runs in the background once macOS goes idle. Same sources, same profiles.

Photo & video editor

With Pro, Slidaria becomes a full toolkit: lift exposure, highlights and shadows, tweak colors, crop photos, trim videos, and export as MP4 — all without switching to another app.

Photo & video editor Pro

Edit without switching apps

Slidaria is more than a player — edit, rotate and color-correct your shots right inside the app. Crop photos, trim videos, fine-tune color and exposure. Originals stay untouched until you turn the editor on.

Photo editor

Brightness, contrast, saturation, warmth. Crop with free or standard aspect ratios. Straighten horizons. Filter presets like B&W, Sepia, Vintage. Correct EXIF dates on old scans. Export as JPEG, PNG, HEIC or TIFF.

Video editor

Trim start and end. Adjust audio levels or mute. Slow-mo (¼x–½x) or time-lapse (2x–8x). Same color and filter controls as the photo editor. Export as MP4 (H.264 or HEVC) up to 4K — directly from the slideshow.

Privacy

Your photos stay with you

Slidaria doesn't need a cloud, an account or a login. We don't track anything, we don't send anything to servers, we don't show ads. Slidaria reads your photos and gives them back unchanged. The screen saver runs offline too.
