Good to know
Questions, answered
WebP or AVIF?
WebP works in every current browser and is usually 25–35% smaller than JPG. AVIF is smaller still but slower to create; use it if your site already serves it.
What size should website images be?
Rarely more than 1920 px wide for full-width images, and 1200 px or less for images inside articles. Bigger files only slow the page down.
Why rename files?
Lowercase names with hyphens work reliably in URLs and are easier for search engines to read than 'IMG_4032 (1).JPG'.
Are my images uploaded?
No. Everything runs in your browser, so your images never leave your device.
