English

Illuminator is a local, lightweight plugin that removes white backgrounds from images, converts them into compact WebP format, and automatically updates links when you paste images or right-click them in the file panel.

🚀 How to Use

Two ways to use this plugin:

  • Auto Mode (Paste): Images are automatically processed when pasted into notes.
  • Manual Mode (Right-Click): Right-click any image in the file panel and select "Illuminator."

Both modes support:

  • Adjustable white removal threshold
  • Output format selection (PNG or WebP)
  • Custom naming — set a pattern or disable it in settings

💡 Tips

  • Best used in Obsidian's Light Mode or with custom backgrounds (e.g., warm yellow, soft green).
  • ⚠️ In Dark Mode, pure black text may become hard to read after white background removal.
  • ⚠️ This process permanently modifies image data. Keep backups if needed.

🛠 How It Works

  • RGB Thresholding: Pixels brighter than your chosen setting become 100% transparent.
  • 100% Local & Private: All processing happens in a Web Worker on your machine. No data ever leaves your vault.

简体中文

Illuminator 是一款本地轻量级插件,可去除图片白色背景,转换为 WebP 格式,并在粘贴或右键点击图片时自动更新链接。

🚀 如何使用

两种使用方式:

  • 自动模式(粘贴): 粘贴图片时自动处理。
  • 手动模式(右键): 在文件面板中右键图片,选择 "Illuminator"。

两种模式均支持:

  • 可调节的白色去除阈值
  • 输出格式选择(PNG 或 WebP)
  • 自定义命名 — 可设置命名模板或禁用

💡 提示

  • 建议在 Obsidian 浅色模式或自定义背景色(如暖黄、淡绿)下使用。
  • ⚠️ 暗黑模式下,去除白色背景后的纯黑色文字可能难以辨认。
  • ⚠️ 此操作会永久修改图片数据,如有需要请提前备份。

🛠 工作原理

  • RGB 阈值处理: 亮度高于设定值的像素变为完全透明。
  • 100% 本地运行: 所有处理在本地 Web Worker 中完成,数据绝不离开你的仓库。

Deutsch

Illuminator ist ein lokales, leichtgewichtiges Plugin, das weiße Hintergründe entfernt, Bilder in WebP konvertiert und beim Einfügen oder Rechtsklick Links automatisch aktualisiert.

🚀 Anwendung

Zwei Nutzungsmöglichkeiten:

  • Auto-Modus (Einfügen): Bilder werden beim Einfügen automatisch verarbeitet.
  • Manueller Modus (Rechtsklick): Rechtsklick auf ein Bild im Datei-Panel und „Illuminator“ wählen.

Beide Modi unterstützen:

  • Einstellbaren Schwellenwert für die Weißentfernung
  • Auswahl des Ausgabeformats (PNG oder WebP)
  • Individuelle Bildbenennung — mit Muster oder deaktivierbar

💡 Tipps

  • Am besten geeignet für den Light Mode von Obsidian oder mit individuellen Hintergrundfarben.
  • ⚠️ Im Dark Mode kann schwarzer Text nach der Weißentfernung schwer lesbar sein.
  • ⚠️ Die Bildänderungen sind dauerhaft. Bitte bei Bedarf Backups anlegen.

🛠 Funktionsweise

  • RGB-Schwellenwert: Pixel heller als der eingestellte Wert werden zu 100 % transparent.
  • 100 % Lokal & Sicher: Die Verarbeitung erfolgt im Web Worker auf deinem Rechner. Keine Daten verlassen dein Vault.

About
Make white backgrounds transparent and convert images into compact WebP when you paste or right-click an image, auto-updating the image link in your notes. Process images entirely locally in a Web Worker for privacy; changes overwrite the original file, so keep backups and prefer use in Light Mode.
