How Placeholder Image Generator Works
The tool draws a solid-color rectangle at your chosen dimensions onto a canvas, then centers your label text (or the dimensions themselves, by default) on top — the result is exported as a downloadable PNG.
How to Use This Tool
- Set the width and height in pixels.
- Pick a background and text color.
- Optionally enter custom label text — leave it blank to show the dimensions automatically.
- Select Generate to preview, then Download PNG.
Example
An 800×450px placeholder with no custom text automatically displays 800 × 450 centered on the image — handy for quickly seeing the size at a glance while laying out a page.
Helpful Tips
- Match the width and height to the exact slot you're designing for, so the placeholder shows real layout behavior.
- Use a mid-tone background color if you're not sure yet — it reads clearly against both light and dark page backgrounds.
Frequently Asked Questions
Is this image uploaded or hosted anywhere?
No, it's generated and downloaded locally — there's no hosted URL, just a PNG file you save to your device.
What's the maximum size I can generate?
Up to 4000×4000px, which comfortably covers typical mockup and layout needs.
Can I use this for a live website mockup URL?
Not directly, since there's no hosting involved — download the PNG and use it as a local placeholder image in your project instead.
