About Placeholder Image Generator
Why use placeholder images?
Web developers need images at exact dimensions to build layouts before real content is ready. Designers need sized boxes to visualize where photos will go in mockups. Placeholder images show the exact pixel dimensions, making it easy to verify that layouts handle different aspect ratios correctly. They're essential for responsive design testing, wireframing, and prototyping.
How it works
Enter your desired width and height in pixels, or click a preset button for common sizes (1920x1080, 1080x1080, 800x600, 300x250 ad banner, 728x90 leaderboard). Choose background and text colors. The default text shows the dimensions but you can enter custom text. The image generates instantly in your browser using canvas rendering.
Export options
Download as PNG (lossless, best for web), JPG (smaller file size), or SVG (scalable, tiny file size). All images are generated client-side on a canvas element. There's no practical limit on dimensions, though very large images may be slow to render.

Frequently Asked Questions
What image formats can I generate?
PNG, JPG, and SVG. PNG is recommended for most web development use. SVG produces the smallest file size since it's vector-based. JPG is best when you need smaller file sizes.
Can I customize the background and text color?
Yes. Use color pickers to set any background color and text color. The defaults are a neutral gray background with darker gray text, but you can match your brand colors.
Are there preset sizes for common use cases?
Yes. Quick presets include: 1920x1080 (Full HD), 1080x1080 (Instagram), 800x600 (standard web), 300x250 (medium rectangle ad), 728x90 (leaderboard ad), 1200x630 (OG image), and 150x150 (thumbnail).
Is there a maximum image size?
There's no hard limit, but your browser's canvas has practical limits. Images up to 4000x4000 generate instantly. Larger sizes work but may take a moment depending on device memory.
