Quick answers
Which is better, WebP or JPG?
For the web, WebP wins: it’s typically 25–35% smaller than JPG at the same visual quality and supports transparency. Keep JPG only when you need maximum compatibility with very old software. You can convert JPG to WebP in seconds.
Should I use PNG or JPG?
Use PNG for logos, screenshots and graphics that need transparency or crisp edges; use JPG for photographs where smaller files matter more than perfect detail. Convert either way with PNG to JPG or JPG to PNG.
Is HEIC or JPG better for sharing iPhone photos?
HEIC saves space on your iPhone, but many apps and Windows PCs can’t open it. Convert to JPG for hassle-free sharing anywhere with the free HEIC to JPG tool.
