Frequently Asked Questions (FAQ)

Depending on the option, images are automatically resized to match the largest or smallest one. Choosing 'Original' will keep their sizes and center-align them.

A.

It's designed to preserve original resolution as much as possible. We minimize unnecessary re-compression during the merge to ensure high-quality results.

Q.Will my personal photos be uploaded to a server?

Don't worry. All operations run within your browser, and not a single byte of your images leaves your device.
