Frequently Asked Questions
We support JPEG, PNG, and WEBP uploads. All outputs are delivered as PNG files by default for maximum quality, especially important for web graphics and logos.
While there’s no hard limit, we recommend images under 5MB for optimal browser performance. Extremely large files may cause slowdowns on older devices.
