Placeholder Image Generator
Generate custom placeholder images with any size, colors and text — download as PNG, JPG or WebP or copy as a data URI. Free, no server.
About the Placeholder Image Generator
Generate clean placeholder images for mockups, wireframes and development in seconds. Enter any width and height up to 4000 pixels, pick a background and text color, and the tool renders a crisp dummy image with the dimensions (or your own custom text) centered on it — previewed live as you type.
Unlike placeholder websites that serve images from their servers, this generator draws everything locally in your browser. That means it works offline, never goes down, adds no external requests to your mockups, and lets you copy the image as a data URI to paste directly into HTML or CSS without hosting any file at all.
Download in PNG for exact colors, JPG for the smallest files or WebP for modern projects. Designers use it for layout comps, developers for seeding test data and image slots, and writers for marking where artwork will go in drafts.

Frequently Asked Questions
How do I create a placeholder image with custom dimensions?
Type the exact width and height you need — say 1200 × 630 for a social preview slot — and the image renders immediately with those dimensions printed in the center. Adjust colors if you like, then download. Any size from 1 × 1 up to 4000 × 4000 pixels works, covering everything from favicons to full-width hero banners.
What is a data URI and when should I copy one?
A data URI encodes the whole image into a text string you can paste straight into an img src attribute or CSS background, with no file to host. It is perfect for quick prototypes and single-file HTML mockups. For large images the string gets bulky — the tool shows the URI size and warns you when downloading a real file would be smarter.
PNG, JPG or WebP — which format should I pick for placeholders?
PNG gives perfectly flat, exact colors and is the safest default for mockups. JPG is smaller but can add faint compression artifacts around text. WebP combines small size with clean rendering in all modern browsers. If the placeholder is temporary anyway, PNG keeps things simple.
Why use this instead of a placeholder image service?
Online placeholder services inject external HTTP requests into your pages, slow down mockups, occasionally shut down and can change their output. This generator runs entirely in your browser: it works offline, produces a real file (or data URI) you control forever, and lets you match your project's exact brand colors.
Can I put my own text on the placeholder instead of the dimensions?
Yes. Type anything into the custom text box — a label like "Hero image", a client name or a note to your future self — and it replaces the default dimension text, centered and auto-sized to fit the image width. Leave the box empty to show the standard width × height label again.
