Frequently Asked Questions (FAQ)
Can I change aspect ratio without cropping parts of my photo?
Yes. In default Fit mode, the entire image remains visible while transparent or colored background padding fills the remaining space to match your target ratio.
Will converting the aspect ratio reduce image quality?
No. High-quality canvas resampling ensures your photo maintains full source resolution and sharpness during export.
