# Placeholder Image Generator: Create Mockup Images Fast
Every web project needs placeholder images during development. You could search for stock photos, but that takes time and creates dependencies. FreeToolJet's Placeholder Image Generator creates custom placeholder images in any size, color, and format — right in your browser.
Why Use Placeholder Images?
- Speed: Generate a 1200×630 hero image in one second, not ten minutes of searching.
- Consistency: Use the same style across all mockups with matching colors and text.
- No licensing: Placeholder images have no copyright restrictions.
- Offline-friendly: Everything renders on the client, no API needed.
How to Generate a Placeholder Image
- Set the width and height in pixels (up to 4096 × 4096).
- Pick background and text colors using the color pickers.
- Optionally type custom text — the default shows dimensions like "800×450".
- Choose format: PNG (lossless), JPEG (smaller), or SVG (vector).
- Click Download to save, or Copy placehold.co URL to use a hosted placeholder.
