What is Image Optimiser by Hafiz?
Image Optimiser by Hafiz is a browser-based tool that reduces image file sizes without uploading your files to external servers. All processing happens locally on your device, which means your images remain private and you can optimise them without an internet connection once the page has loaded. The tool handles common image formats and lets you adjust compression settings to find the right balance between file size and quality. It's useful for anyone who needs to prepare images for websites, emails, or storage without relying on cloud services.
