Placeholder Image Generator — Free SVG Placeholder Tool. Free online placeholder image generator. Create custom SVG placeholders with custom dimensions, colors, and text for web design and UI prototyping.
Our free placeholder image generator creates lightweight SVG placeholders instantly in your browser.
Set custom width and height, pick background and text colors, adjust font size, and add optional label text — the SVG updates in real time so you can preview the result before copying or downloading.
Use it to fill image slots in mockups, wireframes, and prototypes without touching a graphics editor. The tool outputs both raw SVG markup and a Base64 data URI, so you can paste it directly into HTML or use it as a CSS background.
Unlike raster-based dummy image services, this SVG placeholder generator produces vectors that stay crisp at any screen resolution — from mobile thumbnails to 4K hero banners.
All processing runs locally in your browser; no images or dimensions are sent to a server.
Toggle the exact-size switch to control whether the SVG uses fixed width and height attributes or a viewBox-only layout that scales with its container — useful when you need both a pixel-perfect asset and a fluid responsive placeholder from the same tool.
For additional image workflows, combine it with the Base64 File Converter or Image Compressor available on the same platform. A reliable dummy image generator is an everyday necessity for frontend developers and UI/UX designers.
This tool removes the need to install Photoshop, call an external API, or maintain a separate service just to get a placeholder rectangle.
Every placeholder you generate is instantly available as an HTML tag (src="data:image/svg+xml;base64,..."), making it trivial to embed in React, Vue, Angular, or plain HTML projects.
Bookmarking this page gives you a zero-dependency, always-available image placeholder generator that works offline.
Frequently asked questions
How do I generate a placeholder image?
Enter the Width and Height in pixels (600 by 350 by default), pick a Background Color and Text Color, and adjust the Font Size. The preview at the bottom of the page updates instantly. Then click Copy SVG, Copy Base64 or Download SVG.
What text is shown on the placeholder?
By default the image shows its own size, for example 600x350, centred in a monospace font. Type anything into the Text field to replace it with your own label, such as Hero image or Avatar; clear the field to go back to the dimensions.
What does Use Exact Size do?
When it is on, the default, the SVG gets fixed width and height attributes and always renders at that pixel size. Turn it off to output only a viewBox, so the placeholder keeps its aspect ratio but scales to fill its container, which suits responsive layouts.
How do I use the Base64 output?
The SVG in Base64 field holds a data URI that starts with data:image/svg+xml;base64. Paste it into the src attribute of an img tag or into a CSS background-image url() and the placeholder shows up without a separate file or network request.
Can I use special characters such as an ampersand in the text?
Yes. The Text field is XML-escaped before it goes into the SVG, so an ampersand, angle brackets and quotes are written as entities and appear on the image exactly as typed, for example R and D written with an ampersand or a label in angle brackets. The SVG stays valid and the preview keeps working.

Practical tips
Before copying the final result, check important details such as spacing, casing, filenames, encoding, token structure, line breaks, or output format. Small checks prevent mistakes when the result is reused in source code, API requests, documentation, spreadsheets, or shared files.
