# Convert PNG to Optimized PNG Convert PNG images to optimized PNG format with advanced compression settings and quality preservation > Canonical page: https://elysiatools.com/en/tools/png-to-optimized-png - **Category:** Media - **Keywords:** png, optimized, convert, image, format, compression, optimize, advanced ## Overview Reduce the file size of your PNG images without sacrificing visual clarity using our advanced PNG optimization tool. This utility allows you to fine-tune compression levels, color depth, and filtering techniques to achieve the perfect balance between performance and image quality. ## Inputs - **PNG Image File** (file): Select PNG image to optimize - **Quality (0-100)** (range): Higher quality = larger file size. 90+ enables advanced optimizations - **Compression Level (0-9)** (range): 0 = no compression, 9 = maximum compression (slower) - **Progressive PNG** (checkbox): Progressive PNG loads in stages, improving perceived performance - **Adaptive Filtering** (checkbox): Use adaptive filtering for better compression - **Use Color Palette** (checkbox): Convert to 256-color palette for smaller file size - **Force 8-bit Depth** (checkbox): Force 8-bit per channel color depth ## When to use - Reducing image file sizes to improve website loading speeds and SEO performance. - Preparing high-quality graphics for mobile applications where bandwidth is limited. - Optimizing large PNG assets for email attachments or storage-constrained environments. ## How it works - Upload your PNG file to the tool. - Adjust the compression level, quality, and filtering settings to suit your needs. - Apply optional advanced features like progressive loading or color palette reduction. - Download your optimized PNG file instantly. ## Use cases - Web developers optimizing hero images and icons for faster page load times. - Content creators preparing images for high-performance digital marketing campaigns. - App designers minimizing the total build size of mobile software assets. ## Frequently asked questions ### Does this tool reduce image quality? It depends on your settings. Higher compression levels may slightly affect quality, but you can maintain high fidelity by adjusting the quality slider and filtering options. ### What is the maximum file size I can upload? You can upload PNG files up to 50MB in size. ### What does the Progressive PNG option do? Enabling progressive loading allows the image to render in stages, improving the perceived loading speed for users on slower connections. ### Can I convert images to other formats? No, this tool is specifically designed to optimize PNG files while keeping them in the PNG format. ### What is the difference between compression level 0 and 9? Level 0 provides no compression, while level 9 offers the maximum possible compression, resulting in the smallest file size but requiring more processing time. ## Related tools - [Convert JPEG to PNG](https://elysiatools.com/en/tools/jpg-to-png): Convert JPEG images to PNG format with transparency support and lossless compression - [Convert PNG to 8-bit PNG](https://elysiatools.com/en/tools/png-to-8bit-png): Convert PNG images to 8-bit color depth for smaller file size and better compatibility - [Convert PNG to AVIF](https://elysiatools.com/en/tools/png-to-avif): Convert PNG images to AVIF format with next-generation compression and superior quality-to-size ratio - [Convert PNG to BMP](https://elysiatools.com/en/tools/png-to-bmp): Convert PNG images to BMP format with uncompressed quality and broad compatibility - [Convert PNG to HEIF](https://elysiatools.com/en/tools/png-to-heif): Convert PNG images to HEIF format with high efficiency image format - [Convert PNG to Palette-based PNG](https://elysiatools.com/en/tools/png-to-palette-png): Convert PNG images to palette-based format with indexed colors for smaller file size - [Convert PNG to TIFF](https://elysiatools.com/en/tools/png-to-tiff): Convert PNG images to TIFF format with compression options and high quality preservation - [PNG to WebP Converter](https://elysiatools.com/en/tools/png-to-webp): Convert PNG images to WebP format for better compression and web performance ## Samples - [PNG Samples](https://elysiatools.com/en/samples/png-samples): Sample PNG images in different aspect ratios and resolutions - [PNG Viewer Samples](https://elysiatools.com/en/samples/png-viewer-samples): Sample PNG, BMP and AVIF images for the in-browser PNG Viewer - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion - [Web Image Processing Go Samples](https://elysiatools.com/en/samples/web-image-processing-go): Web Go image processing examples including image reading/saving, image resizing, and format conversion ## Related content - [Image Format Conversion and Animated Export Tools](https://elysiatools.com/en/hubs/image-convert): Compare image format converters for JPG, PNG, GIF, AVIF, WebP, TIFF, ICO, base64, and animation-friendly exports in one hub. - [Image Cleanup, Framing, and Batch Prep Tools](https://elysiatools.com/en/hubs/image-utility): Compare image cleanup, trimming, padding, framing, batch resize/compress, watermarking, and visual polish tools in one hub for asset preparation workflows. - [Image Metadata, EXIF, and Privacy Cleanup Tools](https://elysiatools.com/en/hubs/image-metadata): Compare image metadata viewers, EXIF/IPTC/XMP inspectors, orientation fixers, metadata editors, and privacy cleanup tools for photo publishing workflows. - [Image Cleanup, Resize, and Detail Enhancement Tools](https://elysiatools.com/en/hubs/image-cleanup-resize-and-detail-enhancement): Prepare images for delivery with orientation correction, trimming, denoising, resizing, sharpening, and batch conversion.
