Image Format Downloader EN

Image Format Downloader is a comprehensive and user-friendly browser extension designed to streamline the process of converting and downloading images from the web in a variety of popular and custom formats. Tailored for users ranging from graphic designers to educators and content creators, this tool removes the complexities associated with image format incompatibility and manual conversions. With its intuitive popup interface, you can effortlessly scan an active tab for images, input URLs manually, preview converted images, and save them in your preferred format with ease and precision.

This extension supports a wide array of output formats including PNG, JPG/JPEG, WEBP, BMP, as well as customizable MIME types like AVIF—where supported by your browser—enabling you to select the exact format that suits your needs. Input detection is equally robust, recognizing a broad spectrum of image types such as APNG, AVIF, BMP, GIF, ICO, JPG variants, PNG, SVG, WEBP, and even base64-encoded images embedded as data URLs. Whether you want to gather images from a single webpage or convert individual images directly, Image Format Downloader makes this process fast, reliable, and accessible for users of all skill levels.

Beyond its format flexibility, the extension embeds key functionalities such as an automatic scan of the current browser tab to fetch all accessible images—including lazy-loaded images, those linked via srcset attributes, Open Graph meta tags (og:image), and CSS background images—ensuring that no resource goes undetected. An integrated quality adjustment slider allows you to fine-tune output parameters for compressed image formats, balancing between file size and visual fidelity. The extension also offers custom filename support and preview capabilities within its popup interface, so you can verify the output before initiating downloads. To enhance usability, right-click context menu integration lets you convert and download images from any webpage with a single click, using your most recently selected format and settings.

Designed with international users in mind, Image Format Downloader provides auto language detection with support for English and Vietnamese, and respects system-wide preferences such as Dark Mode, offering an adaptive user interface that feels native to your browsing environment. Clear, well-labeled controls make the extension accessible to non-technical users without sacrificing advanced options for power users. Error handling and user notifications are seamlessly integrated to ensure a smooth experience, even when encountering problematic images or unsupported formats.

Privacy is a central priority for Image Format Downloader. The extension does not collect any personal data or analytics, giving you confidence that your browsing habits and image downloads remain fully private and secure. By leveraging advanced browser APIs, the extension conducts all image processing locally using the Canvas element, minimizing dependency on external services and maximizing speed and reliability.
