Frequently Asked Questions

Everything you need to know about image resizing

What is the 4:3 ratio used for?

4:3 is the classic format used in older photography, standard-definition video, and presentations. It is also the native ratio of many point-and-shoot cameras.

What pixel size is 4:3?

Common 4:3 sizes include 1024×768, 1280×960, and 2048×1536. The ratio stays the same regardless of the pixel dimensions.

Is 4:3 good for presentations?

Should I use 4:3 or 16:9 for presentations?

Use 4:3 if you're presenting on an older projector or standard screen. Use 16:9 for modern widescreen displays and projectors. Check your venue's equipment first.

Does cropping reduce image quality?

No. Cropping removes pixels outside the selected area but does not compress or alter the remaining image quality.
