Placeholder Image
Generate solid-color placeholder images at any dimension with size labels. Download for use in mockups and development.

QR codes have become standard in marketing materials, restaurant menus, event tickets, and contactless interactions. The QR Code Generator creates them instantly for any URL, text, or structured data format. Customize foreground and background colors to match your brand, and download as SVG for print (vector, infinite resolution) or PNG for digital use.

The Screenshot Mockup tool places your screenshots into realistic device frames. Upload a screenshot and choose from phone, tablet, laptop, and browser frame options. The result is a polished product image suitable for portfolios, app store listings, pitch decks, and social media posts — without touching Photoshop or paying for a mockup template.

Placeholder images fill space in prototypes and development environments before final assets are ready. This generator creates solid-color images with dimension labels at any size you specify. Unlike URL-based placeholder services, these are downloaded files that work offline and don't depend on third-party availability.
