- SVGs outperformed PNGs. Within the laptops and drugs, SVG vs. PNG efficiency used to be similar. Within the cell gadgets, SVGs have been obviously sharper. General, SVGs have been a lot more forgiving of now not pixel-snapping and extra versatile to scale up and down since they’re vector-based.
- ‘Sharper’ used to be now not all the time higher and almost definitely wishes clearer definition. There are other varieties of sharp. We opened with a common working out of the phrase however there’s some nuance after we follow it. In my find out about, once in a while icons gave the impression sharp however undesirably aliased with (Motorola, Thinkpad). There’s a candy spot to outline. Possibly ‘crisp’ can be a greater phrase to explain sharp, however clean.
The consequences from this check lead me to one (now not new) key advice—use SVGs the place imaginable. They’re essentially the most versatile and forgiving, and carry out best possible total:
- An icon fashion designer can design one dimension that an interface fashion designer can scale to numerous sizes (to the stage that the main points permit; other sizes would possibly require other ranges of element)
- A programmer can dynamically resize the icon in code and follow different transformations like fill colour, stroke colour, and stroke width

- SVGs usually glance crisper than PNGs, even if now not pixel-snapped
- SVG record dimension is smaller than PNG

A handy guide a rough audit of the icons on Fb, Instagram, Google, and Twitter touchdown pages finds that some are pixel-snapped, however many aren’t.
