I Built Bulk Image Resizer

Bulk Image Resizer is an in-house macOS app we built to take the slow, repetitive part out of preparing images for the web. Drop in a folder of photos, choose your dimensions and output format, and the app handles the rest — no upload, no queue, no third-party service touching client assets.

The interface is built in React and TypeScript, while the actual encoding and resizing runs in native Rust through Tauri. That split keeps the UI responsive during large batches and gives us near-native throughput on hundreds of files at once. Because everything runs locally, image data never leaves the machine.

We use it on nearly every project to generate the optimized WebP assets that ship with the sites we design and build.
