How to prepare image assets for a website

Start with a clean source image, select the asset family, then download consistent filenames and an implementation snippet.

Create app icons

Generate classic favicons, Apple touch icon, Android/PWA icons and a web manifest in one ZIP.

Build responsive images

Export several WebP widths and copy a srcset/sizes snippet so the browser can choose a suitable resource.

Create lightweight previews

Use a dominant color and tiny blurred Data URI while the full image loads.

Developer-ready output

The exported ZIP includes assets and code together, reducing naming and installation mistakes.

Standard size package

Generate common browser, Apple and PWA sizes from one square source.

Performance hints

Responsive widths and placeholders help avoid sending one oversized image to every device.

Creative utilities

Create or split spritesheets, scale pixel art and inspect repeating texture seams.

Web image assets FAQ

Which favicon and PWA sizes are included?

The package includes 16, 32 and 48 px favicons, 180 px Apple touch icon, and 192 and 512 px Android/PWA icons.

How does responsive srcset help?

It gives the browser multiple image widths plus layout hints so it can choose a resource suited to the display slot and pixel density.

Are Base64 placeholders always faster?

No. They reduce an extra request for a tiny preview but increase HTML or CSS bytes. Measure them in the real page.
