WLED Preset Editor

Standalone browser-based editor for presets.json

Load a presets.json exported from your WLED device, edit it visually, and export it back. No installation, no server — everything runs locally in the browser.

You can edit every field defined in the WLED JSON API: name, brightness, transition, on/off state, and all segment parameters including effect, speed, intensity, palette, colors, LED range, grouping, CCT, and custom sliders. Select multiple presets with the checkboxes to apply bulk changes across all of them at once.
