About Placeholder Image Generator
This placeholder image generator makes blank dummy images at any dimension for mockups, wireframes, email templates, and web layouts. Set a width and height (or pick a preset like 1200×630, 1080×1080, or a standard ad banner size), choose background and text colors, and type any label you want. If you leave the label blank it shows the pixel dimensions, the way most placeholder services do.
Everything is drawn locally with the browser's Canvas API — no image is ever uploaded and nothing leaves your device. You can download the result as a PNG, JPG, WebP, or a scalable SVG, copy an inline data-URI string to paste straight into HTML or CSS, or copy a ready-made <img> tag with the correct width, height, and alt attributes.
Because it renders client-side, there is no external server and no hotlink URL: the file you download is self-contained. Raster formats (PNG/JPG/WebP) are fixed at the pixel size you set, while SVG stays sharp at any scale. Very large sizes are capped at 6000 px per side to keep the browser responsive.
Frequently asked questions
- What is a placeholder image used for?
- Placeholder (or dummy) images fill space in a design before the real photos exist — in website mockups, wireframes, email templates, app prototypes, and print layouts. They let you see how a layout flows at the correct dimensions without waiting on final assets.
- Can I set any width and height?
- Yes. Enter any custom pixel dimensions up to 6000×6000, or pick a preset such as 1200×630 (social/OG), 1080×1920 (story/reel), or common ad banner sizes like 728×90 and 300×250. Use the Swap button to flip width and height.
- Which file formats can I download?
- PNG (lossless), JPG (smaller, no transparency), WebP (modern and compact), and SVG (vector that scales to any size without blurring). You can also copy a data-URI string or a complete <img> tag instead of downloading a file.
- Is my image uploaded anywhere?
- No. The image is generated entirely in your browser using the Canvas API. Nothing is sent to a server, so it works offline and keeps your text and colors private.
- How do I use the data URI it copies?
- The 'Copy data URI' button gives you an inline data: string. Paste it into an HTML img src, a CSS background-image, or an email template and the image displays with no external file — useful for self-contained mockups.
- Can I change the label text and font size?
- Yes. Type any text in the label field (leave it blank to show the dimensions), and set a fixed font size or leave it at 0 to auto-fit the text to the image.
