Frequently Asked Questions
What is a Lorem Ipsum Image / Dummy Placeholder?
A dummy placeholder image (often called Lorem Ipsum Image) is a temporary graphic used during website design, prototyping, and development. It fills visual space where final images will eventually go, helping designers and developers visualize layouts without needing actual photography or final artwork.
What size should my placeholder image be?
Choose dimensions that match your final image requirements. Common sizes include 800×600 for general use, 1920×1080 for hero banners, 1200×628 for social media sharing, 300×250 for ads, and 375×667 for mobile mockups. Our tool includes preset sizes for quick selection.
Which format should I choose - PNG, JPEG, WebP, or SVG?
PNG offers lossless quality and supports transparency. JPEG provides smaller file sizes ideal for photos. WebP combines small size with excellent quality, supported by all modern browsers. SVG is resolution-independent and perfect for responsive designs, with the smallest file size for simple graphics.
How do I choose the right colors for my placeholder?
Use a neutral background like light gray (#e0e0e0) for generic placeholders. Match your brand colors if the placeholder represents branded content. Ensure sufficient contrast between background and text for readability. Dark backgrounds with white text work well for hero image placeholders.
Can I download the generated placeholder image?
Yes! Click the "Download Placeholder Image" button to save the image directly to your device. The download respects your selected format (PNG, JPEG, WebP, or SVG). All generation happens locally in your browser - no uploads, no waiting, and complete privacy.
Can I use this tool offline?
Absolutely! All image generation is done client-side using Canvas API and SVG rendering directly in your browser. There's no server dependency, no API calls, and no internet connection required once the page loads. Your images are never uploaded anywhere.
What does the aspect ratio lock do?
The lock feature maintains proportional dimensions when you adjust width or height. Enable it and select a ratio like 16:9 or 4:3. Then, when you change one dimension, the other updates automatically to preserve the chosen proportions - perfect for ensuring your placeholder matches specific layout requirements.
