Frequently Asked Questions (FAQ)
What happens if I set fixed pixels for images with different aspect ratios?
If "Maintain aspect ratio" is checked, your input is treated as a "Max Bounding Box". The system will proportionally scale each image to fit entirely within these bounds without distortion. Unchecking it will force stretch the images to your exact dimensions.
What image formats are supported?
We support most mainstream formats including JPG, JPEG, PNG, WEBP, BMP, and static GIF. High quality is maintained by default upon export.
