LilyView — Mac download

LilyView is an image viewer that reads pictures straight from your folders—no libraries, no imports. Double-click a file and you get the photo, nothing else. It’s a chromeless window that stays out of your way until you need a control.

Jump to native resolution and back with one command

• Original size toggle — one command to see the photo at its native resolution, then back to fit.
• Gesture-driven browsing — swipe through a folder of images with trackpad gestures; keyboard and mouse input work just as well.
• Format coverage — handles JPEG, PNG, TIFF, and animated GIFs without plugins.
• True chromeless mode — the window frame disappears, leaving only the image on screen.

A focused alternative to Preview

Preview is a document viewer that happens to open images. LilyView does one job. It skips the sidebar, the markup toolbar, and the document thumbnails to give you a clean view of a photo. For anyone who works through folders of images regularly, that focus means less friction between opening a file and seeing it properly.

First days with LilyView: quick wins

Install, then pick a folder with mixed formats—JPEGs, a few PNGs, maybe an animated GIF. Double-click the first image. Immediately, the window frame vanishes. That’s the default state, not a mode you hunt for.

Three habits worth forming early:

• Set automatic zoom to width — under the Browse tab, pick the fit‑to‑width option. Photos fill the window horizontally on first open; no more squinting at a tiny default size.
• Learn the right‑edge hover — move your pointer to the right side of the screen in full‑screen view. Image attributes slide into view without covering the photo. It’s the quickest way to check dimensions or file name mid‑browse.
• Jump to ends — when a folder holds hundreds of shots, use the Browse tab’s first/last commands instead of swiping through every image. Saves minutes on the first pass.

If you currently rely on Preview for image browsing, give LilyView a dedicated folder for a day. The absence of a sidebar and toolbar feels odd for about ten minutes, then it feels faster. That’s the point.

Borderless window from first launch on any Mac

The 1.7.0 update tightened the chromeless behaviour. Earlier builds sometimes showed a thin title bar on launch; the current release opens directly into a borderless window on both Intel and Apple Silicon Macs running macOS 10.13 or later.

Gesture responsiveness improved noticeably. Swiping through a folder of high‑resolution TIFFs used to pause on the first frame—now the next image appears during the swipe, not after it. Double‑tap to full‑screen also registers more reliably on trackpads that previously needed a firmer press.

Under the hood, the app gained proper ARM support. On Apple Silicon machines, image decoding runs natively, which keeps the app cool and responsive even when flipping through large RAW‑converted JPEGs. The interface languages remain English and Russian, and the format list—JPEG, PNG, TIFF, animated GIF—stays the same, with no new plug‑in dependencies.

New

• "Fit to Screen" view option. Smaller images now stretch to fill the available screen space automatically.

Improved

• The previous non-stretching view is renamed "Actual Size Limited by Screen."

• macOS 12 or later
• Apple Silicon or Intel 64-bit processor
