Recommended Settings by Use Case
Web Photos
Quality: 75-85
Ideal for general photos on websites and blogs. Balances file size and image quality well.
Social Media Posts
Quality: 80-90
Works well for images posted to Instagram, Twitter, Facebook, etc. Maintains sufficient quality even after re-compression by social media platforms.
High Quality Required
Quality: 90-100
Use when image quality is the top priority, such as portfolios or print materials. Results in larger file sizes.
Email Attachments
Quality: 60-75
Best when you need to minimize file size. Useful for email sending or when there are data capacity limitations.

Frequently Asked Questions
What's the difference between JPG and JPEG?
JPG and JPEG are the same image format. Only the file extension differs—the content is identical.
Will the converted image quality degrade?
Since JPG uses lossy compression, some degradation may occur depending on quality settings. However, with settings of 80-90, visual differences are barely noticeable.
What happens when converting transparent images?
Transparent areas are filled with a white background. For images requiring transparency, we recommend using the PNG converter tool.
How much can file size be reduced?
Depending on the original image format and quality settings, you can typically achieve 30-60% reduction from PNG and 10-30% reduction from WebP.
Usage Notes
When converting large images or many images, processing may take time depending on browser capabilities. Always visually confirm image quality after conversion before use.
