Store](https://chromewebstore.google.com/detail/photo-exif-util/jfofoaeeaeonemgkamhiefekfgfjbamd)\n\n### Developer build (manual install)\n\n1. Download `photo-exif-util-v\u003cVERSION\u003e.zip` from the [Releases page](https://github.com/mkontani/photo-exif-util/releases) and unzip it\n2. Open `chrome://extensions/` and enable **Developer mode**\n3. Click **Load unpacked** and select the unzipped folder\n\n## Usage\n\n1. Open the side panel via:\n   - The toolbar icon → **Open side panel**, or\n   - Right-click an image → **Open with Photo EXIF Util**, or\n   - Keyboard shortcut `Ctrl+Shift+E` (macOS: `⌘+Shift+E`)\n2. Provide an image by drag-and-drop, file picker, or URL\n3. Use the **Inspect / Strip / Optimize** tabs to operate\n\n## Browser compatibility\n\n| Browser | Side panel | Note |\n|---|---|---|\n| Chrome / Edge / Brave (Chromium 116+) | ✅ Works natively | |\n| Vivaldi | ⚠️ Manual Web Panel setup required | See below |\n\n### Vivaldi: manual side panel setup\n\nVivaldi does not yet wire the Chromium `chrome.sidePanel` API up to its sidebar\nUI (the API call resolves silently but no panel appears). As a workaround,\nregister Photo EXIF Util as a **Web Panel** in Vivaldi's sidebar:\n\n1. Open `vivaldi://extensions/` and copy the **extension ID** of Photo EXIF\n   Util (a long hash such as `hdonilpdcgefacepilobkebniklaomld`).\n2. Build the side-panel URL:\n   `chrome-extension://\u003cEXTENSION_ID\u003e/src/ui/side-panel/index.html`\n3. Click the **+** at the bottom of Vivaldi's sidebar → **Add Web Panel** →\n   paste the URL → confirm.\n4. Click the new Web Panel icon in the sidebar to open Photo EXIF Util.\n\nAfter registration:\n\n- **Right-click → Open with Photo EXIF Util** still works — the image URL is\n  handed off via `chrome.storage.session`, and the Web Panel picks it up the\n  next time it's open. Open the Web Panel from the sidebar first if it isn't\n  already shown.\n- The **toolbar icon** and **`Ctrl+Shift+E`** shortcut are no-ops in Vivaldi\n  because they rely on the unimplemented `chrome.sidePanel.open` API. Use the\n  sidebar Web Panel icon instead.\n\nIf a future Vivaldi release implements `chrome.sidePanel`, the extension will\nwork without this manual setup automatically.\n\n## Privacy\n\nThis extension **never sends image data outside your device**. All processing\nhappens locally in the browser. See [PRIVACY.md](./docs/PRIVACY.md) for details.\n\n## Development \u0026 Contributing\n\nSee [CONTRIBUTING.md](./CONTRIBUTING.md) for development setup and conventions.\nRelease flow is documented in [docs/RELEASE.md](./docs/RELEASE.md).\n\n## License\n\n[MIT](./LICENSE) © 2026 Photo EXIF Util Contributors\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmkontani%2Fphoto-exif-util","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmkontani%2Fphoto-exif-util","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmkontani%2Fphoto-exif-util/lists"}
