The Importance of Aspect Ratio Locks
When resizing graphical photographs, manual arithmetic often introduces subtle fractional errors. An aspect ratio is the exact proportional multiplier between the horizontal width and vertical height. For example, a 1920x1080 video represents a standard 16:9 ratio.
If you arbitrarily change the width to 800 without proportionally adjusting the height down to exactly 450, the resulting canvas becomes permanently squashed and visually distorted. By utilizing mathematical aspect locks, typing into one box cascades to perfectly mirror the necessary calculation onto the other axis immediately.
Lossy vs Lossless Exports
- PNG (Lossless): Retains exact pixel clarity and completely supports alpha transparency (ideal for logos). Huge file sizes.
- JPG (Lossy): Efficient for enormous photographs. Throws away visually invisible data to dramatically slash megabytes off the file. Does not support transparent backgrounds.
- WebP: A modern Google protocol that successfully marries high visual quality with vastly superior compression matrix algorithms compared to JPGs.
