⚠️ Technical Limitations & Best Practices
Calculators provide mathematical estimates based on user inputs. Bank fees, processing charges, and tax law amendments may affect real-world figures. Always maintain a backup of your original source files. Output metrics (such as exact byte size and visual sharpness) are determined by input quality, color depth, and complexity.
