Modern websites often serve images in WebP format, which some users dislike or cannot use. The extension solves the 'WebP problem' by letting users right-click any image and save it as PNG or JPG instead, avoiding the unreliable 'Save Image As' browser behavior that may save unwanted WebP files.

User right-clicks any image on a webpage → context menu appears with format options (PNG/JPG/WebP) → user selects desired format → extension loads image into an offscreen canvas, draws it, and exports via canvas.toDataURL() in the chosen format → downloads the converted image file using chrome.downloads API

Target users: Users who frequently download images from the web and prefer PNG or JPG over WebP / Designers, content creators, or anyone who needs images in specific formats / Users frustrated by browsers saving images as WebP when they want standard formats

Code is minified/bundled (webpack), making line-by-line analysis harder but the logic is fully readable
No content scripts declared in manifest but inject.js is programmatically injected via chrome.scripting.executeScript

Monetization

No paid features detected

No payment platforms, subscription logic, premium tiers, or feature gating detected. The 'pro' keyword hits are false positives from the minified webpack module system. All three format options (PNG, JPG, WebP) are available to all users without restriction.

Confidence: 97
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension works entirely locally using Chrome context menus, canvas-based image conversion, and the chrome.downloads API. No authentication endpoints, login UI, or account creation flows exist in the codebase. The 'session' keyword hit is from Google Analytics session tracking (chrome.storage.session for client ID), not user authentication.
