Frequently Asked Questions

What is a placeholder image generator?
A placeholder image generator creates temporary, customizable images (dummy images) that developers and designers use during website or app development. Instead of waiting for final assets, you can quickly generate images at any size with custom colors and text.
How do I use this tool?
Simply set the width and height (in pixels), choose background and text colors, optionally add your own text, and pick a format. The preview updates instantly. Click Download to save the image, or Copy Image URL to get a shareable data URL.
What image formats are supported?
PNG, JPEG, and WebP. PNG is recommended for sharp text and transparency (though we use solid backgrounds). JPEG offers smaller file sizes for photos. WebP provides both lossy and lossless compression with great quality-to-size ratio.
Are there any size limits?
You can generate images from 1Ă—1 up to 4000Ă—4000 pixels. Very large sizes may take a moment to render and the download file size will increase accordingly. Keep it reasonable for web use.
Is the generated image safe and private?
Absolutely. All image generation happens directly inside your browser using HTML5 Canvas — no data is ever uploaded to any server. Your designs stay completely private.
Can I use the generated images commercially?
Yes, the images are yours to use however you like. There’s no copyright on simple colored rectangles with text. Use them in mockups, prototypes, presentations, or even live websites.
