Frequently Asked Questions
Can I control the logo size?
Yes, you can set the logo's size as a percentage of the base image's width, from 5% to 60%.
Are my images uploaded to any server?
Not at all — the entire merge happens inside your browser directly via Canvas, and your images never leave your device.
What logo formats are supported?
You can upload a logo in any common image format (PNG, JPG, WebP); PNG with a transparent background is recommended for the best result.
