App dictates format
- Using Illustrator — Export SVG
- Using Photoshop — Export JPG (or PNG)
Default to SVG
If you can use an SVG—use an SVG
Backup is JPG
Photos should be JPGs
Try to avoid PNGs
In most cases anything that can be done in a PNG can be done better in an SVG*
*In most cases
- GIFs are huge files!
- They have poor user experience
- Bad accessibility: flashing that can cause seizures & can’t be stopped
Avoid them at all costs.
