Frequently Asked Questions
When should I use quality reduction?
Use it for thumbnails, preview images, email attachments, social media uploads, and any case where loading speed matters more than perfect image fidelity.
What is the minimum quality I should use?
For recognizable images, we recommend at least 20-30%. Below 15% most images become noticeably degraded.
