E-Ink Image Converter

PersonalWeb2026DesignerDeveloper

Project Summary

This tool converts regular images into formats optimized for e-ink displays, running entirely in the browser with no server required. Drop in a batch of images and it resizes them to your display, applies dithering, and exports BMP files ready to load onto the device.

It was built with Svelte 5 and includes presets for common displays like Waveshare panels and Kindles, along with a 3D frame viewer built with Three.js that previews converted images on a realistic e-ink device mockup.
