β¦ Placeholder Image Generator
Custom-size placeholders with text for developers and designers.
How to Generate a Placeholder
Enter dimensions, pick colors, add an optional label, and download. Quick-size buttons cover common ad and social dimensions.
Set width and height in pixels, or click a quick size like 728 by 90 or 1080 by 1080.
Choose background and text colors that match your mockup palette.
Type custom text, or leave it blank to show the dimensions automatically.
Adjust font size and download as PNG or JPG.
Why Generate Placeholders Locally
Classic placeholder services work by hotlinking images from a URL, which means your development site depends on an external server. If that service is slow, down, or discontinued, your mockups break. Generating the file locally and saving it with your project removes that dependency entirely. It also keeps internal project names and dimensions private instead of broadcasting them in third-party server logs. For design systems, consistent placeholder styling matters: use your brand gray ramp for backgrounds and a single text color so every mockup across the team looks like it came from the same kit. Dimension-labeled placeholders are especially useful in responsive design reviews because stakeholders can see at a glance which asset size each slot expects. When handing off to developers, placeholders with exact pixel dimensions eliminate guesswork about image requirements. They also make great Open Graph test images and email template spacers during development.
Tips for Better Mockups
Use realistic aspect ratios even in early wireframes, because layout problems hide when every box is square. A hero placeholder at 1920 by 1080 behaves very differently from one at 800 by 600 once real photography arrives. Vary background shades slightly between adjacent placeholders so individual image slots are visually distinct in the mockup. Keep text short: a two-word label like Product Shot reads better than a sentence. For dark-mode mockups, flip the palette to dark backgrounds with light text so the placeholder matches the theme you are presenting.
Frequently Asked Questions
What are placeholder images used for?
Designers and developers use placeholders in mockups, wireframes, and unfinished web pages to reserve space for final imagery. They make layouts testable before photography is ready, communicate exact required dimensions to the team, and keep stakeholders focused on structure rather than missing assets. Dimension-labeled placeholders are the industry standard in professional mockups.
Can I use these in client presentations?
Yes, and they look professional. Clean placeholders with dimension labels show clients exactly where content will go and demonstrate that the layout is intentional. They are far better than empty gray boxes or broken image icons. Just remember to replace them with real licensed images before the site launches.
What is the maximum size?
You can generate images up to 4000 by 4000 pixels. That covers everything from tiny 160 by 600 ad units to full-screen 1920 by 1080 hero banners and even 4K mockup backgrounds. Larger sizes take only a moment longer to render since generation happens instantly on the canvas.
Does the text auto-fit?
Yes. If your custom text is too wide for the image, the font size shrinks automatically until it fits within 90 percent of the width. Leave the text field blank to show the dimensions instead, which is the classic developer placeholder style.
PNG or JPG, which should I pick?
Choose PNG for the sharpest result: it keeps text and flat colors pixel-perfect, which is what you want in mockups. Choose JPG when file size matters more than crispness, such as placeholders standing in for large photographic hero images. For typical wireframe and design review use, PNG is the safer default.
Can I hotlink the generated image like other placeholder services?
No, and that is a feature, not a limitation. Classic placeholder services work by hotlinking, which makes your project depend on an external server that could slow down, rate-limit, or disappear. Downloading the file and hosting it with your project removes that dependency entirely and keeps internal project details out of third-party server logs.
