Features

Just enough viewer.

← / →

Browse the folder, not a library

Open one image; arrow keys step through siblings in the same directory. No vault, no thumbnails strip, no library sidebar.

Fit · 100% · Free

Three zoom modes

Fits to window by default. Ctrl 1 for actual size, Ctrl scroll to zoom anywhere on the cursor.

Click-drag

Pan when zoomed

Grab and drag the image when it's larger than the window. Subtle scrollbars too.

Fullscreen

One key removes the titlebar and status line. Just the image. Esc to return.

PNG · JPEG · WebP · GIF · AVIF · SVG · BMP · ICO

Whatever the webview renders

No heavyweight decoder bindings. Animated GIFs, WebP, and AVIF play on loop automatically.

Tauri · Rust

Native Linux

Small binary. Real file associations. Set as the default for image files via the .deb.

Krill principles

A simple interface.

Focus One app, one job. One file, one window. No tabs, no project trees, no mode pickers — the work in front of you is the work.

Beauty A locked palette, careful typography, chrome that sits still. The apps shouldn't be the part of your desktop you have to forgive.

Simplicity No settings panel, no plugin system, no power-user knobs. If a feature can't be explained in a sentence, it doesn't ship.

Ownership Your files on your disk in their original format. No accounts, no cloud, no telemetry. MIT licensed; build it yourself if you don't trust ours.

Install

Quick install

One-liner — downloads the AppImage to ~/.local/bin, marks it executable, and registers a launcher entry. Re-run to upgrade.
