Open images in one window →Windows Photos, macOS Preview and most desktop viewers open each picture in its own window, and arranging four of them on screen is manual, fragile work that breaks the moment you zoom one of them. This tool replaces that with a single browser tab holding up to nine images in an automatic grid.
Because it runs in the browser, it works identically on Windows, macOS, Linux, and even tablets — no installation, and your images are processed locally without being uploaded.
How to use
- 1Open the tool — it starts with a multi-zone grid.
- 2Add or remove zones to match how many images you need (1–9).
- 3Load images by drag & drop, batch upload, clipboard paste or URL.
Why use this tool
One window, up to 9 images
The grid manages the layout for you and adapts when you resize the browser.
Works everywhere
Any OS with a modern browser — nothing to install, nothing to configure.
More than a viewer
When you need it: synchronized zoom, pixel diff, curtain slider, A/B flash and color picker.
Frequently Asked Questions
How is this better than opening files in my OS viewer?
One window instead of many, automatic layout, synchronized zoom across images, and comparison modes no basic viewer has.
Can I paste a screenshot directly?
Yes — press Ctrl+V (Cmd+V on Mac) with a zone focused and the clipboard image loads instantly.
Does it work offline?
After the page has loaded, image viewing and comparison run entirely locally in the browser.
