Frequently Asked Questions
What quality setting should I use?
For web images, 70-80% quality provides excellent results with significant file size reduction. For archival purposes or high-quality prints, use 90-95%. Below 70% may show visible compression artifacts.
How much can JPEG files be compressed?
Typical compression rates range from 30-80% file size reduction. The actual compression depends on image content - photos with smooth gradients compress better than images with lots of detail or text.
Will compression affect image dimensions?
No, our tool maintains the original image dimensions (width and height) by default. Only the file size is reduced through quality optimization. Use our resize tool if you need to change dimensions.
Is JPEG compression lossy?
Yes, JPEG uses lossy compression, meaning some image data is permanently removed to achieve smaller file sizes. However, at quality settings above 80%, the visual difference is typically imperceptible to the human eye.
