Frequently Asked Questions
What is a placeholder image and when should I use one?▼
A placeholder image is a temporary image used during website or app development to represent where final images will go. They are commonly used in wireframes, mockups, prototypes, and during front-end development when real content isn't available yet. Placeholder images help maintain layout structure and give stakeholders a visual sense of the final design.
What image formats can I generate with this tool?▼
This tool supports three output formats: PNG (best for general use and maximum compatibility), SVG (vector format that scales perfectly at any size with tiny file sizes), and WebP (modern format with excellent compression, supported by all major browsers). All images are generated entirely in your browser — nothing is uploaded to any server.
What are common placeholder image sizes for social media?▼
Common social media image sizes include: Facebook cover (820x312), Twitter/X header (1500x500), Instagram post (1080x1080), YouTube thumbnail (1280x720), LinkedIn banner (1584x396), and app icons (512x512). This tool includes all these as one-click presets so you can generate the right size instantly.
