Placeholder Image Generator - Create Custom Placeholder Images Online
A placeholder image generator creates dummy images with configurable dimensions, colors, shapes, and text. Designers and developers use placeholder images during prototyping and development to reserve space for images that will be added later. This tool runs entirely in your browser - no upload, no sign-up, no server processing.
How do I create a custom placeholder image?
Set the width and height in pixels, pick background and foreground colors, and optionally enter custom text. The preview updates in real time so you can fine-tune the result. When you are happy with the preview, click Download JPG or choose another format from the dropdown. The image is generated on a Canvas element in your browser and downloaded instantly.
What image formats can I download?
The tool supports JPG, PNG, WEBP (in browsers that support it), and SVG. JPG is the default because it produces small files that work everywhere. PNG supports transparency and is ideal for circle-shaped placeholders. WEBP offers superior compression for modern browsers. SVG produces a vector file that scales to any size without pixelation - useful for responsive mockups and print.
How do I create a circular placeholder image?
Switch the shape selector from Rectangle to Circle, then set the diameter. The canvas becomes a square with a filled circle. When you download as PNG or WEBP the area outside the circle is transparent; when you download as JPG the background color fills the corners automatically.
What are the most common placeholder image sizes?
The tool ships with ready-made presets for frequently used dimensions: 512 × 512 square, 1920 × 1080 (Full HD), 3840 × 2160 (4K), 1200 × 630 (Open Graph / social-media sharing image), and 32 × 32 (favicon). You can also enter any custom size up to 8192 px per side.
Can I use my own background image instead of a solid color?
Yes. Upload any image through the Background Image field and it will be drawn behind the text, scaled to cover the full canvas. This is useful for generating watermarked previews or for overlaying dimension labels on existing artwork.
How do I add custom text to a placeholder?
By default the placeholder displays the dimensions - for example 1920 × 1080. Enter any text in the Custom Text field to replace it. The text is rendered in a monospace font and automatically scaled to fit within 85 % of the canvas width, so even long strings stay readable.
Why do developers use placeholder images?
Placeholder images let front-end developers build and test layouts before real assets are available. They make it easy to verify responsive breakpoints, check image-loading behaviour, and communicate dimensions to designers. Using generated placeholders avoids the need for external services and keeps development entirely local.
What is the difference between JPG, PNG, WEBP, and SVG placeholders?
JPG files are small and universally supported but do not support transparency. PNG files support alpha transparency, making them the best choice for circle-shaped placeholders. WEBP files combine small file sizes with transparency support but are not supported in older browsers. SVG files are vector-based, resolution-independent, and ideal for documentation or print mockups.
Is this placeholder image generator free?
Yes, the tool is completely free and runs entirely in your browser. No files are uploaded to any server, no account is required, and there are no watermarks on the generated images. Your data stays on your device.
Can I copy the placeholder as a data URL?
Yes. Open the download dropdown next to the main Download JPG button and select Copy JPG Data URL. The base64-encoded JPG data URL is copied to your clipboard and can be pasted directly into CSS, HTML <img> tags, or code editors.
