Frequently Asked Questions (FAQs)
1. How does batch resizing work?
Simply select multiple images using the drag-and-drop area. Set your desired dimensions and format. The tool will process all images at once and generate a single ZIP file containing your resized photos.
2. Does converting PNG to JPG maintain transparency?
No, the JPG file format technically does not support transparency. When you use our tool to convert a transparent PNG to JPG, it automatically applies a clean white background to ensure the image looks perfect.
