Convert images to PNG, JPG, WebP or AVIF locally with real codecs. Live preview, size compare, no tracking. Open source. Convert images to PNG, JPG, WebP or AVIF — entirely on your device, using real image codecs compiled to WebAssembly. It reads the common web image formats (including WebP and AVIF) and re-encodes them with professional-grade quality. No servers. No tracking. No ads. Open source. ━━━━━━━━━━━━━━━━━━━━━━ WHY IT'S DIFFERENT ━━━━━━━━━━━━━━━━━━━━━━ Most converter extensions rely on the browser's basic canvas export, which silently drops quality, mishandles modern formats, and struggles with large images. Converter Pro uses dedicated WebAssembly codecs — the same kind of encoders behind professional tools — for predictable, high-quality results: • True AVIF support via libavif — real decode and encode, not a checkbox • mozjpeg encoding — typically smaller files at the same visual quality • libwebp with both lossy and lossless modes • Correct image orientation, so photos are never saved sideways ━━━━━━━━━━━━━━━━━━━━━━ PREVIEW STUDIO ━━━━━━━━━━━━━━━━━━━━━━ Open any image in Studio to decide before you save: • See the result and its file size before downloading • Before / after slider to compare the original with the converted image • Live quality slider — the preview and file size update as you drag • Transparency fill control (white, black or custom) when converting to a format without an alpha channel ━━━━━━━━━━━━━━━━━━━━━━ FAST EVERYDAY USE ━━━━━━━━━━━━━━━━━━━━━━ • Right-click any image to save it in your chosen format • Keyboard shortcuts — hover an image and press a hotkey (works on galleries where right-click is blocked) • Smart detection finds the image even behind overlays or CSS backgrounds • Warns you about search-engine thumbnails so you don't save a tiny preview • Drag and drop local files into the popup ━━━━━━━━━━━━━━━━━━━━━━ PRIVACY ━━━━━━━━━━━━━━━━━━━━━━ Everything happens locally in your browser. No image, URL, or usage data ever leaves your device. There are no servers, no analytics, no ads, and no third-party tracking. The full source code is open and auditable. Why this extension asks for "all sites" access: images on a page are often served from a different domain than the page itself. The extension needs to read the image data to convert it. That data is processed on your device and discarded after conversion — it is never sent anywhere. Open source (MIT). Built on the Squoosh / jSquash WebAssembly codecs.
