About This Tool
Image Compressor reduces image file sizes while maintaining visual quality. Adjust the quality slider to find the perfect balance between file size and image clarity. Optionally resize images during compression by setting maximum dimensions. Supports output in JPEG, PNG, and WebP formats — WebP typically produces the smallest files at equivalent quality.
