About Base64 Decoding:This tool converts Base64 encoded strings back to their original image format. You can paste Base64 strings directly, upload text files containing Base64 data, or provide complete data URIs. The tool automatically detects the image format and provides multiple download options including compression.
🔧 Browser-Based Compression Technology
Smart Compression:Uses advanced algorithms to automatically optimize image quality and file size based on the selected format and settings.
Format Support:Supports JPEG, PNG, and WebP formats with automatic format detection and conversion.
Privacy First:All compression happens locally in your browser - no files are uploaded to any server for maximum privacy and security.
Progressive JPEG:Creates images that load progressively, improving perceived performance on slower connections.
