## What it does

A lightweight Windows app for converting and resizing images in bulk. Drop in everyday photos, phone HEICs or RAW files straight off a camera, and it exports clean JPEG, PNG or WebP files into a `converted` folder next to your originals — nothing gets overwritten.

- Reads **PNG, JPG, BMP, TIFF, WebP, HEIC/HEIF** and **camera RAW** (Nikon NEF/NRW, Canon CR2/CR3/CRW, Sony ARW/SR2, Adobe DNG, Olympus ORF, Panasonic RW2, Fujifilm RAF, Pentax PEF and more).
- Exports **JPEG, PNG or WebP** with a quality slider from 1 to 100.
- **Resize** by a fraction (½ down to 1/20) or set a max width and height — aspect ratio is kept and images are only ever scaled down.
- **True batch** processing, with live progress as the queue clears.
- Full-resolution RAW demosaic with **camera white balance** for accurate color.
- Drag-and-drop, a responsive thumbnail grid and a clean **dark theme**.
