Browser extension that enables in-browser viewing of HEIC photos and HEVC videos by communicating with a local Synology desktop app to generate previews and compressed videos

Browsers natively cannot display HEIC/HEVC formats. This extension, paired with a desktop app, automatically generates browser-compatible previews and compressed versions when uploading or viewing media files on Synology NAS web interfaces.

User installs the Chrome extension and the companion Synology desktop app. When the user browses photos or uploads files in a Synology web interface, the content script detects media operations and communicates with the desktop app via native messaging. The desktop app generates browser-compatible previews/thumbnails for HEIC images and transcodes HEVC videos, which are then displayed in the browser.

Target users: Synology NAS users who browse photos/videos via Synology web applications / Users working with Apple-originated HEIC/HEVC media formats in browser-based NAS interfaces

Source code is heavily minified, making deep inspection of logic difficult
Cannot determine if the companion desktop app requires a Synology account/login
Cannot determine if the companion desktop app or Synology NAS service has paid tiers that affect extension functionality

Monetization

No paid features detected

The extension is a free utility that bridges the browser to a local Synology desktop app. The heuristic-detected 'upgrade' keyword refers to websocket protocol upgrade in bundled socket.io code, not paid upgrades. The 'purchase' hit is also in bundled/minified code without billing context. The 'pro' keyword matches in locale files are substrings of words like 'processador' (Portuguese) or 'processor', not a 'pro' plan. No payment platforms, subscription APIs, billing endpoints, or upgrade UI were found in the source. The extension does not gate any features behind payment.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension itself does not implement any login UI, authentication flow, or account system. The only permissions are 'storage' and 'nativeMessaging' — no 'identity' permission. The extension communicates with a local Synology desktop app via native messaging, and its popup simply shows connection detection status (whether the desktop client is installed/running). The 'auth' keyword hits in source are from bundled socket.io library code (websocket protocol internals), not authentication UI.
