Convert image formats effortlessly between JPG, PNG, WebP, AVIF, BMP, and GIF. ToolLok’s Image Format Converter runs completely on the client-side utilizing your browser’s built-in canvas processing engine. This means you can bulk convert, resize, and optimize dozens of high-resolution photos instantly without ever uploading your personal files to an external server.
When converting images, our tool automatically strips hidden metadata including GPS location coordinates, camera models, and timestamps, ensuring your privacy is protected before you share photos online.
Don't use a second tool to shrink your images. Use the advanced settings to scale your photos down by a percentage or enforce a maximum width to perfectly optimize your assets for website performance.
For modern web design, WebP or AVIF are heavily recommended by Google. They provide superior compression compared to standard JPGs and PNGs, drastically improving your page load speeds and Core Web Vitals scores without sacrificing visual quality.
By default, JPG formats do not support transparency. However, our advanced settings automatically fill transparent pixels with a solid white background (or any custom color you choose) during the conversion process to prevent unsightly black artifacts.
Because ToolLok performs conversions locally inside your browser, there are no artificial file size limits or paywalls. Your only limit is the available RAM (memory) on your phone or computer.
Yes! The conversion engine relies on HTML5 technologies that execute directly inside your device. Your sensitive data, photographs, and screenshots are never uploaded or tracked.
