Paste Image as WebP

Convert images pasted from the clipboard into WebP format automatically when inserting them into your notes. Supports customizable file names, WebP compression quality, save destinations, and automatic embedding in the editor.

Features

  • Automatically converts clipboard images to WebP on paste
  • Two filename modes:
    • Fixed name: e.g. image.webp
    • Timestamp: e.g. 20231116143025.webp
  • Adjustable WebP quality (0.1–1.0)
  • Configurable save folder (vault root, same folder as current note, or a custom path)
  • Inserts ![[filename.webp]] at the cursor automatically
  • Duplicate filenames are resolved by appending a numeric suffix
  • Built-in size limits to guard against malicious or oversized images

Installation

From the Community Plugins directory (recommended once approved)

  1. Open Settings → Community plugins → Browse.
  2. Search for Paste Image as WebP.
  3. Click Install, then Enable.

Manual installation

  1. Download main.js, manifest.json, and styles.css from the latest release.
  2. Create a folder paste-image-as-webp inside <your-vault>/.obsidian/plugins/.
  3. Copy the three files into that folder.
  4. Restart Obsidian and enable the plugin from Settings → Community plugins.

Usage

  1. Enable the plugin in Settings → Community plugins.
  2. Open the plugin settings to configure:
    • Filename format: fixed name or timestamp.
    • Fixed filename (when fixed mode is selected).
    • Timestamp format (when timestamp mode is selected).
    • Image folder location: vault root, same folder as the current note, or a custom path.
    • Image folder name or custom folder path.
    • Image quality (WebP): 0.1–1.0.
  3. Copy an image to the clipboard and paste (Ctrl+V / Cmd+V) into the editor.

Timestamp tokens

YYYY year, MM month, DD day, HH hour (24h), mm minute, ss second.

Examples:

  • YYYYMMDDHHmmss → 20231116143025.webp
  • YYYY-MM-DD_HHmmss → 2023-11-16_143025.webp

Security settings

  • Maximum image size: maximum total pixels (width × height). Default 16777216 (4096 × 4096).
  • Maximum file size (MB): maximum input file size in megabytes. Default 10.

These limits prevent malicious images from consuming excessive resources during decoding. See SECURITY.md for details.

Network and file system use

This plugin does not make any network requests and does not read or write files outside the current vault. All image conversion is performed locally in the browser/Electron renderer using the <canvas> toBlob('image/webp', …) API.

Development

This project uses pnpm as its package manager. npm install is blocked by a preinstall guard.

git clone https://github.com/CocoaAI-IT/paste-image-as-webp.git
cd paste-image-as-webp
pnpm install
pnpm dev      # watch mode
pnpm build    # production build

  • クリップボードから画像をペーストすると自動的に WebP に変換
  • ファイル名形式: 固定名 / タイムスタンプ
  • WebP 品質を 0.1〜1.0 で調整可能
  • 保存先: Vault ルート / 現在のノートと同じフォルダ / カスタムパス
  • 同名ファイルは自動で連番付与
  • 画像サイズ・ファイルサイズの上限設定（DoS 対策）

使い方

  1. 設定 → コミュニティプラグイン から Paste Image as WebP を有効化
  2. プラグイン設定でファイル名形式・保存先・品質などを設定

ネットワーク・ファイルシステム

このプラグインは外部通信を一切行わず、Vault 外のファイルにアクセスすることもありません。画像変換は <canvas> の toBlob('image/webp', …) API を使って端末内で完結します。
