Browse Photos at Thumbnails
Up to 1000px

ExplorerLargerer is a Windows photo browser that shows thumbnails way larger than Explorer's maximum "Extra Large" size — a scrollable grid from 80px to 1000px, with a live slider to dial in exactly the size you want.

The Problem

Windows Explorer maxes out at 256px thumbnails. That's fine for spotting a filename — it's useless for actually looking at photos. When you want to visually scan a folder full of pictures, you end up double-clicking every single file, flipping through a viewer, and losing your place in the grid.

ExplorerLargerer blows past that limit. Point it at any folder and browse the photos in a scrollable grid at anywhere from 80px to 1000px thumbnails — big enough to actually see what's in each shot without opening a single one.

What It Does

One window, one job — a photo grid at whatever thumbnail size you want:

80px to 1000px Thumbnails
A scrollable grid of photos at any thumbnail size from 80px all the way to 1000px — nearly four times Explorer's maximum.
Live Resize Slider
Drag the slider and the whole grid resizes instantly — dial in exactly the size you want while you browse.
Click to Open
Click any photo to open it in your default viewer — ExplorerLargerer is for scanning, your viewer is for viewing.
Dark UI + Shortcuts
A dark interface that stays out of the way, with keyboard shortcuts: Ctrl+O to open a folder, + and - to nudge thumbnail size up or down.

Install

ExplorerLargerer is free and open source under the MIT license. It requires Windows and Python 3.10+ with Pillow.

pip install pillow python explorer_largerer.py python explorer_largerer.py "C:\Users\You\Pictures"

Or double-click ExplorerLargerer.bat — edit the Python path inside if needed.
