How Image Size Calculation Works
This calculator helps you estimate the impact of resizing and converting images to different formats. The calculations are based on typical compression ratios for each format.
Key factors affecting file size:
- Dimensions: Smaller images require fewer pixels and thus less data
- Format: Modern formats like WebP and AVIF offer better compression
- Quality: Higher quality settings result in larger files
- Image content: Photos with more detail and colors compress less than simple graphics
Note: These are estimates only. Actual results may vary based on image content and compression settings.
