Placeholder Image Generator
Free online placeholder image generator. Create custom dummy images with any size, background color, font color, and text. Export as PNG or SVG for web design, mockups, and prototyping.
What is a placeholder image?
A placeholder image is a temporary image used during web development and design to fill space where final content will eventually appear. Also known as dummy images, test images, or mockup images, they help developers and designers visualize layouts before real content is available.
What image formats are supported?
You can download placeholder images as PNG or SVG. PNG is a raster format suitable for all uses, while SVG is a vector format that scales perfectly at any size without quality loss.
What is the maximum image size?
The maximum dimension is 4000 pixels for both width and height. This covers virtually all use cases from small UI elements to full-page hero banners.
Can I customize the text on the placeholder?
Yes, you can enter any custom text. By default, the dimensions (e.g., "800×600") are displayed, but you can replace this with any text you need, such as "Banner Image" or "Product Photo".
Are the images generated on a server?
No, all images are generated entirely in your browser using the Canvas API. No data is sent to any server, ensuring complete privacy and instant generation.
Can I use these images commercially?
Yes, all generated placeholder images are free to use for any purpose, including commercial projects, client presentations, and portfolio work.
How do I choose the right background and text colors?
Use the color pickers to select any color. For best contrast, choose a light background with dark text or a dark background with light text. You can also enter hex color codes directly.
Why use a placeholder image generator?
Placeholder images speed up development by letting you build and test layouts without waiting for final assets. They're essential for wireframing, prototyping, client presentations, and testing responsive designs across different screen sizes.
Can I generate multiple images at once?
Each generation creates one image. However, you can quickly adjust dimensions and regenerate to create a set of placeholder images for different layout positions.
Do the images include transparency?
PNG format supports transparency. If you need a transparent placeholder, set the background to transparent and download as PNG. SVG format does not support transparency in this tool.
Is there a limit on how many images I can generate?
No, there is no limit. You can generate as many placeholder images as you need, completely free.
Can I use placeholder images for social media?
Yes, you can set custom dimensions matching social media sizes (e.g., 1200×630 for Facebook, 1080×1080 for Instagram) and use them as posting templates or content placeholders.
How to Use Placeholder Image Generator
Create dummy images in any size, color, and text for mockups and prototypes. Everything renders locally in your browser, and no image data ever leaves your device.
- Click a preset size button such as 150×150, 800×600, or 1920×1080 to resize the placeholder with one click.
- For a custom dimension, type your own numbers into the Width (px) and Height (px) fields instead of using a preset.
- Use the Background and Text Color pickers to match your design palette exactly.
- Type the caption you want displayed in the Custom Text field, then adjust Font Size so it stays readable at any dimension.
- Export the finished placeholder as PNG for raster mockups or as SVG for crisp, scalable results.
Prefer SVG export for wireframes you plan to stretch or shrink; it stays sharp at every size and adds only a few bytes.
