WebP / Avif image Converter: convert, download and store images from the web just the way you want.

How does it work?

After downloading the extension you get a new button *Convert and Save image as* in the image context menu (When you right click on an image). Now the image is being processed and downloaded based on your preferences. Conversion to JPG, PNG and WebP are supported.

These preferences can be set in the option menu that you can reach by clicking on the extensions’ browser button located on the top right of your browser next to the address bar.

Note that the "browser button" may be hidden. If you want to quickly change the settings pin it to your extension bar. This can be done by clicking on the "extension" (looks like a puzzle piece) next to the hamburger menu / user login. Find the button and click on "pin".

AI product read

Image format converter that adds a right-click context menu option to convert and download web images in a different format (JPG, PNG, or WebP)

WebP and Avif images are not universally compatible or desired; this extension lets users quickly convert and save them as JPG, PNG, or WebP with customizable quality and download paths

User installs extension → right-clicks any image on a webpage → selects 'Convert and save image as' from context menu → extension fetches the image, converts it using Canvas/OffscreenCanvas based on user's configured conversion rules (per image type, quality, background color) → downloads the converted file to the configured path with a templated filename.

Target users: Web developers and designers who need images in specific formats / General users who want to save WebP/Avif images as JPG/PNG / Users who need batch-rename or organize downloaded images

No external service calls detected beyond standard Google CRX update URL, so no remote API to inspect for gating
The extension has both manifest v2 and v3 versions but the analysis focused on the v3 service worker entry point

Monetization

No paid features detected

No payment platforms, premium features, subscriptions, or licensing mechanisms found in the source code. The 'upgrade' keyword hits are all data model version migrations (e.g. migrating stored settings from version 0 to version 1, 2, 3, etc.), not paid upgrades. All image conversion features (JPG, PNG, WebP output with quality control, download path customization) are available to all users without restriction.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally in the browser. It uses Canvas/OffscreenCanvas APIs for image conversion and the Chrome downloads API for saving files. No authentication, account creation, or external service login is required. The 'token' keyword hits are filename template placeholders (e.g. <originalname>, <originaltype>) used for download path customization, not authentication tokens.
