Convert images to PNG, JPG, WebP, AVIF, or ICO locally. Drag and drop, batch, no uploads, no ads. Quillmorph converts images right in your browser. Drop in a file, pick a format, and get it back in seconds. Nothing uploads, so your images never leave your machine. Most converters handle one input and one output, or push you to a website that uploads your files. Quillmorph reads the formats you actually run into, including the WebP and AVIF that older apps can't open, and turns them into whatever you need next. GIF, BMP, and SVG work as inputs too, and you can save your result as PNG, JPG, WebP, AVIF, or an ICO favicon. It does more than one-off conversions. Convert a whole folder at once and download the results together as a zip. Set the quality when you're saving to JPG, WebP, or AVIF. Turn a transparent image into a JPG on a clean white background instead of a black one. Build a multi-size ICO favicon from any image. Everything happens in your browser using its built-in graphics. Quillmorph makes no network requests, collects nothing, and has no account system. You can confirm it yourself in the Network tab: nothing leaves your machine.
