Frequently asked questions
Are JPG and JPEG different formats?
They are filename extensions for the same format here and use the same compression workflow.
How do I avoid visible artifacts?
Start from the original rather than repeatedly compressing a low-quality JPG. Lower quality gradually and compare details.
Are files uploaded?
No. Image processing happens in your browser.
