Question 1

What is an SVG placeholder image?

Accepted Answer

An SVG placeholder is a lightweight, scalable vector image used during development or design to represent a final image that hasn't been created yet. Because SVG is text-based, placeholders are tiny in file size and render crisp at any resolution.

Question 2

How do I use the SVG data URI in HTML?

Accepted Answer

Paste the data URI directly into the src attribute of an img tag: <img src="data:image/svg+xml;utf8,..." />. This embeds the image inline without any external HTTP request, making it ideal for mockups, emails, and rapid prototyping.

Question 3

What presets are available?

Accepted Answer

The tool includes common presets: 16:9 (1280x720), 4:3 (800x600), 1:1 square (400x400), Banner (728x90), OG Image (1200x630), and Twitter Card (1200x675). You can also enter any custom width and height.

Question 4

Can I customise the text and colours?

Accepted Answer

Yes. You can set any background colour, text colour, and custom label text. If you leave the text blank, the tool defaults to showing the image dimensions (e.g. 400x300).
