Technical Details
This generator uses the HTML5 Canvas API to render placeholder images entirely in the browser. Images are drawn with a background fill, subtle cross lines for visual reference, and centered text. The Canvas toDataURL() method generates PNG data URIs for download and copying. The tool is 100% client-side with no server interaction.
Frequently Asked Questions
What is the maximum image size?
The maximum supported size is 4096×4096 pixels. Larger dimensions may work depending on your browser's Canvas limits, but are not guaranteed.
Can I use the data URI directly in my code?
Yes! Click 'Copy Data URI' to copy the base64-encoded image data URI. You can use it directly in CSS background-image properties or HTML img src attributes.
Is there a watermark on generated images?
No. Generated images contain only your custom text (or dimensions by default) on the background color. There are no watermarks or branding added.
