FAQ
- Does resizing reduce quality? Scaling down keeps images sharp, while scaling beyond the original size can soften detail.
- Is the aspect ratio preserved? Yes — with keep aspect ratio enabled, changing one field updates the other automatically.
- Which output format should I pick? Choose PNG for transparency and crisp edges, or JPEG when a smaller file matters more.
