# Convert PNG to 8-bit PNG Convert PNG images to 8-bit color depth for smaller file size and better compatibility > Canonical page: https://elysiatools.com/en/tools/png-to-8bit-png - **Category:** Media - **Keywords:** png, 8bit, bit-depth, convert, image, format, compression, optimize, depth ## Overview Easily convert high-bit depth PNG images to 8-bit PNG format to significantly reduce file size while maintaining visual quality and improving cross-platform compatibility. ## Inputs - **PNG Image File** (file): Select PNG image to convert to 8-bit - **Quality (0-100)** (range): Quality of the 8-bit conversion process - **Compression Level (0-9)** (range): 0 = no compression, 9 = maximum compression - **Adaptive Filtering** (checkbox): Use adaptive filtering for better compression ## When to use - When you need to reduce the file size of web assets for faster page loading. - When preparing images for legacy systems or software that only support 8-bit color palettes. - When you want to optimize PNG images for mobile applications with strict storage constraints. ## How it works - Upload your source PNG file to the converter. - Adjust the quality, compression level, and adaptive filtering settings to suit your needs. - Process the image to generate an optimized 8-bit version. - Download your converted file directly to your device. ## Use cases - Optimizing website icons and UI elements for faster rendering. - Reducing the footprint of game assets in mobile development. - Standardizing image formats for email newsletters and digital marketing materials. ## Frequently asked questions ### What is an 8-bit PNG? An 8-bit PNG uses a color palette of up to 256 colors, which significantly reduces the file size compared to 24-bit or 32-bit images. ### Will I lose image quality? Converting to 8-bit may result in minor color loss, but you can adjust the quality slider to find the best balance between file size and visual fidelity. ### What does the compression level do? The compression level ranges from 0 to 9, where 9 provides the maximum file size reduction. ### Is adaptive filtering necessary? Enabling adaptive filtering helps the encoder choose the best compression strategy for each row of pixels, often resulting in smaller files. ### Are there file size limits? Yes, you can upload PNG files up to 50MB for conversion. ## 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 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 Optimized PNG](https://elysiatools.com/en/tools/png-to-optimized-png): Convert PNG images to optimized PNG format with advanced compression settings and quality preservation - [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.
