appkiro.comPlaceholder Generator creates simple filler images at any size you need. Set the dimensions, pick colors, add optional label text, and download a PNG or SVG — all in the browser, with no account or upload required.
A placeholder image is a blank, labeled graphic used to hold space in a layout before real content is ready. This tool generates them on demand: you define the width, height, background color, text color, and an optional label, then export as a raster PNG or a scalable SVG. The preview updates live as you change any setting.
Reach for this tool any time you need an image of a specific size but the real asset is not available yet. Common moments include early-stage wireframing, handing off a component to a developer before the design is finalized, building a demo or prototype for a client review, or writing documentation that needs visual examples without using real user data.
Is there a maximum image size?
The width and height inputs accept values up to 4096px. Very large PNG files may take a moment to generate since the canvas has to fill every pixel in the browser.
What does Copy Data URL do?
It copies a base64-encoded version of the image as a data URI — a self-contained string that starts with data:image/png;base64,... or data:image/svg+xml;base64,.... You can paste it directly as an image source in HTML, CSS, or design tools that accept data URIs, without needing to host the file anywhere.
Can I use a custom font or add more styling?
The tool uses a monospace font and centers the text automatically. For more complex placeholder designs — custom fonts, borders, icons — an SVG editor or a design tool would give you more control.
Why does the preview look smaller than the actual dimensions?
The preview is scaled down to fit the panel. The downloaded file is always at the exact pixel dimensions you entered — the preview is just a visual reference.
Can I use these images in production?
Technically yes, but placeholder images are meant to be temporary. They carry no licensing restrictions since they are generated entirely in your browser, but they are not a substitute for real content in a finished product.
Does the tool store or upload my images?
No. Everything is generated locally using the browser Canvas API. Nothing is sent to any server.
