Frequently Asked Questions
Does cropping reduce image quality?
No. Cropping extracts the selected area at its original resolution. The only quality consideration is the output format · JPEGs use a high quality setting (92%) to minimize artifacts.
Can I crop to exact pixel dimensions?
The crop selection shows its pixel dimensions in real time. For exact pixel sizes, use our Image Resizer tool after cropping to scale the result to precise dimensions.
Is my image uploaded anywhere?
No. All cropping happens in your browser using the Canvas API. Your image stays on your device the entire time.
