1. What is JPG Quality?

JPG quality refers to the trade-off between image quality and file size when saving JPEG images. Higher quality means less compression and larger file size, while lower quality means more compression and smaller file size.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Quality — The resulting image quality percentage (0-100%)
• Compression Level — The amount of compression applied (0-100%)

Explanation: The quality percentage is simply the inverse of the compression level percentage in standard JPEG settings.

3. Importance of Quality Calculation

Details: Understanding the relationship between quality and compression helps in optimizing images for web use, balancing visual quality with file size requirements.

4. Using the Calculator

Tips: Enter the compression level percentage (0-100) to calculate the corresponding quality percentage. A compression level of 0 means no compression (100% quality), while 100 means maximum compression (0% quality).

5. Frequently Asked Questions (FAQ)

Q1: What is a good quality setting for web images?
A: Typically 60-80% quality provides a good balance between quality and file size for web use.

Q2: Does higher quality always mean better?
A: Not necessarily - quality above 90% often results in much larger files with minimal visible improvement.

Q3: How does compression affect image quality?
A: Higher compression (lower quality) can cause artifacts like blurring, blocking, and ringing around edges.

Q4: Is this calculator applicable to all image formats?
A: No, this specifically applies to JPEG/JPG format which uses lossy compression.

Q5: Can I get the original quality back after compression?
A: No, JPEG compression is lossy - once compressed, the original quality cannot be fully restored.
