Every design starts before the real photography exists. Placeholder images hold the space — showing layout, proportion and rhythm while content is still being made. This generator creates them properly: any width and height, your background and text colours, and a custom label (or the dimensions themselves), rendered and downloaded as a PNG in one click. No external placeholder service, no hotlinking, no waiting — the image is drawn on your device and works offline. Good placeholders do one more job beyond filling space: they document intent. A holder labelled “Hero — kitchen scene, morning light” tells the photographer, illustrator or future you exactly what belongs there, while a bare grey box starts an argument later. Use the label field that way on real projects — content description plus dimensions — and your mockups become a shot list. For pure layout testing, remove labels entirely so stakeholders judge structure, not imaginary content.
Quick Answer: Set the width and height, pick colours, type a label, and download the PNG. The preview updates live so the placeholder matches your layout before you export it.

Best Practices and Tips
- Match the placeholder to the final image’s aspect ratio so the layout never shifts when real content lands.
- Use a consistent grey family for wireframes so stakeholders judge layout, not colours.
- Label placeholders with their purpose (“Hero 1600×900”) to brief photographers and designers.
- For responsive designs, generate the largest size and let CSS scale it down.
- Reserve image slots with fixed dimensions in CSS to prevent layout shift, placeholder or not.
- Generate placeholders at the exact aspect ratio of the final design, not just the exact width — ratio mismatches are what cause the layout shift everyone blames on slow images later.
Common Mistakes to Avoid
- Hotlinking third-party placeholder services that may vanish or change.
- Using colourful placeholders in wireframe reviews, distracting from structure feedback.
- Forgetting the final image replacement — placeholders have a habit of reaching production.
- Generating at display size only, then finding the image blurry on retina screens; export at 2×.
Frequently Asked Questions
What sizes can I generate?
Any width and height between 10 and 3000 pixels — banners, squares, story formats and everything between.
What text appears on the image?
Your custom label if you type one; otherwise the dimensions, such as “800 × 600”, are centred on the image.
Can I use these in client mock-ups?
Yes — the images are generated fresh in your browser and are free to use in any project, commercial or personal.
Does anything get uploaded?
No. The PNG is drawn on a canvas in your browser.
Is this generator free?
Yes — free, unlimited and no sign-up required.
Can placeholders match my brand colours?
Yes — set background and text colours to your palette so early mockups already feel on-brand, which noticeably improves stakeholder feedback quality.
